+/**
+ `AFHTTPSessionManager` is a subclass of `AFURLSessionManager` with convenience methods for making HTTP requests. When a `baseURL` is provided, requests made with the `GET` / `POST` / et al. convenience methods can be made with relative paths.
+
+ ## Subclassing Notes
+
+ Developers targeting iOS 7 or Mac OS X 10.9 or later that deal extensively with a web service are encouraged to subclass `AFHTTPSessionManager`, providing a class method that returns a shared singleton object on which authentication and other configuration can be shared across the application.
+
+ ## Methods to Override
+
+ To change the behavior of all data task operation construction, which is also used in the `GET` / `POST` / et al. convenience methods, override `dataTaskWithRequest:uploadProgress:downloadProgress:completionHandler:`.
+
+ ## Serialization
+
+ Requests created by an HTTP client will contain default headers and encode parameters according to the `requestSerializer` property, which is an object conforming to `<AFURLRequestSerialization>`.
+
+ Responses received from the server are automatically validated and serialized by the `responseSerializers` property, which is an object conforming to `<AFURLResponseSerialization>`
+
+ ## URL Construction Using Relative Paths
+
+ For HTTP convenience methods, the request serializer constructs URLs from the path relative to the `-baseURL`, using `NSURL +URLWithString:relativeToURL:`, when provided. If `baseURL` is `nil`, `path` needs to resolve to a valid `NSURL` object using `NSURL +URLWithString:`.
+
+ Below are a few examples of how `baseURL` and relative paths interact:
+
+    NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
+    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
+    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
+    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
+    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
+    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
+    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/
+
+ Also important to note is that a trailing slash will be added to any `baseURL` without one. This would otherwise cause unexpected behavior when constructing URLs using paths without a leading slash.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

+ Creates an `NSMutableURLRequest` object with the specified HTTP method and URLString, and constructs a `multipart/form-data` HTTP body, using the specified parameters and multipart form data block. See http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.2
+
+ Multipart form requests are automatically streamed, reading files directly from disk along with in-memory data in a single HTTP body. The resulting `NSMutableURLRequest` object has an `HTTPBodyStream` property, so refrain from setting `HTTPBodyStream` or `HTTPBody` on this request object, as it will clear out the multipart form body stream.
+
+ @param method The HTTP method for the request. This parameter must not be `GET` or `HEAD`, or `nil`.
+ @param URLString The URL string used to create the request URL.
+ @param parameters The parameters to be encoded and set in the request HTTP body.
+ @param block A block that takes a single argument and appends data to the HTTP body. The block argument is an object adopting the `AFMultipartFormData` protocol.
+ @param error The error that occurred while constructing the request.

+
+ @discussion There is a bug in `NSURLSessionTask` that causes requests to not send a `Content-Length` header when streaming contents from an HTTP body, which is notably problematic when interacting with the Amazon S3 webservice. As a workaround, this method takes a request constructed with `multipartFormRequestWithMethod:URLString:parameters:constructingBodyWithBlock:error:`, or any other request with an `HTTPBodyStream`, writes the contents to the specified file and returns a copy of the original request with the `HTTPBodyStream` property set to `nil`. From here, the file can either be passed to `AFURLSessionManager -uploadTaskWithRequest:fromFile:progress:completionHandler:`, or have its contents read into an `NSData` that's assigned to the `HTTPBody` property of the request.

+/**
+ `AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+ ## Subclassing Notes
+
+ This is the base class for `AFHTTPSessionManager`, which adds functionality specific to making HTTP requests. If you are looking to extend `AFURLSessionManager` specifically for HTTP, consider subclassing `AFHTTPSessionManager` instead.
+
+ ## NSURLSession & NSURLSessionTask Delegate Methods
+
+ `AFURLSessionManager` implements the following delegate methods:
+
+ ### `NSURLSessionDelegate`
+
+ - `URLSession:didBecomeInvalidWithError:`
+ - `URLSession:didReceiveChallenge:completionHandler:`
+ - `URLSessionDidFinishEventsForBackgroundURLSession:`
+
+ ### `NSURLSessionTaskDelegate`
+
+ - `URLSession:willPerformHTTPRedirection:newRequest:completionHandler:`
+ - `URLSession:task:didReceiveChallenge:completionHandler:`
+ - `URLSession:task:didSendBodyData:totalBytesSent:totalBytesExpectedToSend:`
+ - `URLSession:task:needNewBodyStream:`
+ - `URLSession:task:didCompleteWithError:`
+
+ ### `NSURLSessionDataDelegate`
+
+ - `URLSession:dataTask:didReceiveResponse:completionHandler:`
+ - `URLSession:dataTask:didBecomeDownloadTask:`
+ - `URLSession:dataTask:didReceiveData:`
+ - `URLSession:dataTask:willCacheResponse:completionHandler:`
+
+ ### `NSURLSessionDownloadDelegate`
+
+ - `URLSession:downloadTask:didFinishDownloadingToURL:`
+ - `URLSession:downloadTask:didWriteData:totalBytesWritten:totalBytesExpectedToWrite:`
+ - `URLSession:downloadTask:didResumeAtOffset:expectedTotalBytes:`
+
+ If any of these methods are overridden in a subclass, they _must_ call the `super` implementation first.
+
+ ## Network Reachability Monitoring
+
+ Network reachability status and change monitoring is available through the `reachabilityManager` property. Applications may choose to monitor network reachability conditions in order to prevent or suspend any outbound requests. See `AFNetworkReachabilityManager` for more details.
+
+ ## NSCoding Caveats
+
+ - Encoded managers do not include any block properties. Be sure to set delegate callback blocks when using `-initWithCoder:` or `NSKeyedUnarchiver`.
+
+ ## NSCopying Caveats
+
+ - `-copy` and `-copyWithZone:` return a new manager with a new `NSURLSession` created from the configuration of the original.
+ - Operation copies do not include any delegate callback blocks, as they often strongly captures a reference to `self`, which would otherwise have the unintuitive side-effect of pointing to the _original_ session manager when copied.
+
+ @warning Managers for background sessions must be owned for the duration of their use. This can be accomplished by creating an application-wide or shared singleton instance.

If you want AFNetworking to handle the authentication challenge, just return `@(NSURLSessionAuthChallengePerformDefaultHandling)`. For example, you certainly want AFNetworking to handle certificate validation (i.e. authentication method == `NSURLAuthenticationMethodServerTrust`) as defined by the security policy. If you want to handle the challenge yourself, you have four options:
+ 
+ 1. Return `nil` from the authentication challenge handler. You **MUST** call the completion handler with a disposition and credentials yourself. Use this if you need to present a user interface to let the user enter their credentials.
+ 2. Return an `NSError` object from the authentication challenge handler. You **MUST NOT** call the completion handler when returning an `NSError `. The returned error will be reported in the completion handler of the task. Use this if you need to abort an authentication challenge with a specific error.
+ 3. Return an `NSURLCredential` object from the authentication challenge handler. You **MUST NOT** call the completion handler when returning an `NSURLCredential`. The returned credentials will be used to fulfil the challenge. Use this when you can get credentials without presenting a user interface.
+ 4. Return an `NSNumber` object wrapping an `NSURLSessionAuthChallengeDisposition`. Supported values are `@(NSURLSessionAuthChallengePerformDefaultHandling)`, `@(NSURLSessionAuthChallengeCancelAuthenticationChallenge)` and `@(NSURLSessionAuthChallengeRejectProtectionSpace)`. You **MUST NOT** call the completion handler when returning an `NSNumber`.
+ 
+ If you return anything else from the authentication challenge handler, an exception will be thrown.

+         iOS 7 and iOS 8 differ in NSURLSessionTask implementation, which makes the next bit of code a bit tricky.
+         Many Unit Tests have been built to validate as much of this behavior has possible.
+         Here is what we know:
+            - NSURLSessionTasks are implemented with class clusters, meaning the class you request from the API isn't actually the type of class you will get back.
+            - Simply referencing `[NSURLSessionTask class]` will not work. You need to ask an `NSURLSession` to actually create an object, and grab the class from there.
+            - On iOS 7, `localDataTask` is a `__NSCFLocalDataTask`, which inherits from `__NSCFLocalSessionTask`, which inherits from `__NSCFURLSessionTask`.
+            - On iOS 8, `localDataTask` is a `__NSCFLocalDataTask`, which inherits from `__NSCFLocalSessionTask`, which inherits from `NSURLSessionTask`.
+            - On iOS 7, `__NSCFLocalSessionTask` and `__NSCFURLSessionTask` are the only two classes that have their own implementations of `resume` and `suspend`, and `__NSCFLocalSessionTask` DOES NOT CALL SUPER. This means both classes need to be swizzled.
+            - On iOS 8, `NSURLSessionTask` is the only class that implements `resume` and `suspend`. This means this is the only class that needs to be swizzled.
+            - Because `NSURLSessionTask` is not involved in the class hierarchy for every version of iOS, its easier to add the swizzled methods to a dummy class and manage them there.
+        
+         Some Assumptions:
+            - No implementations of `resume` or `suspend` call super. If this were to change in a future version of iOS, we'd need to handle it.
+            - No background task classes override `resume` or `suspend`
+         
+         The current solution:
+            1) Grab an instance of `__NSCFLocalDataTask` by asking an instance of `NSURLSession` for a data task.
+            2) Grab a pointer to the original implementation of `af_resume`
+            3) Check to see if the current class has an implementation of resume. If so, continue to step 4.
+            4) Grab the super class of the current class.
+            5) Grab a pointer for the current class to the current implementation of `resume`.
+            6) Grab a pointer for the super class to the current implementation of `resume`.
+            7) If the current class implementation of `resume` is not equal to the super class implementation of `resume` AND the current implementation of `resume` is not equal to the original implementation of `af_resume`, THEN swizzle the methods
+            8) Set the current class to the super class, and repeat steps 3-8

+
+AFNetworking is a delightful networking library for iOS, macOS, watchOS, and tvOS. It's built on top of the [Foundation URL Loading System](https://developer.apple.com/documentation/foundation/url_loading_system), extending the powerful high-level networking abstractions built into Cocoa. It has a modular architecture with well-designed, feature-rich APIs that are a joy to use.
+
+Perhaps the most important feature of all, however, is the amazing community of developers who use and contribute to AFNetworking every day. AFNetworking powers some of the most popular and critically-acclaimed apps on the iPhone, iPad, and Mac.
+
+## How To Get Started
+
+- [Download AFNetworking](https://github.com/AFNetworking/AFNetworking/archive/master.zip) and try out the included Mac and iPhone example apps
+- Read the ["Getting Started" guide](https://github.com/AFNetworking/AFNetworking/wiki/Getting-Started-with-AFNetworking), [FAQ](https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-FAQ), or [other articles on the Wiki](https://github.com/AFNetworking/AFNetworking/wiki)

+
+## Installation
+AFNetworking supports multiple methods for installing the library in a project.
+
+## Installation with CocoaPods
+
+To integrate AFNetworking into your Xcode project using CocoaPods, specify it in your `Podfile`:
+
+```ruby
+pod 'AFNetworking', '~> 4.0'
+```
+
+### Installation with Swift Package Manager
+
+Once you have your Swift package set up, adding AFNetworking as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.
+
+```swift
+dependencies: [
+    .package(url: "https://github.com/AFNetworking/AFNetworking.git", .upToNextMajor(from: "4.0.0"))
+]
+```
+
+> Note: AFNetworking's Swift package does not include it's UIKit extensions.
+
+### Installation with Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate AFNetworking, add the following to your `Cartfile`.
+
+```ogdl
+github "AFNetworking/AFNetworking" ~> 4.0
+```

+
+## Usage
+
+### AFURLSessionManager
+
+`AFURLSessionManager` creates and manages an `NSURLSession` object based on a specified `NSURLSessionConfiguration` object, which conforms to `<NSURLSessionTaskDelegate>`, `<NSURLSessionDataDelegate>`, `<NSURLSessionDownloadDelegate>`, and `<NSURLSessionDelegate>`.
+
+#### Creating a Download Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
+    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
+    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
+} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
+    NSLog(@"File downloaded to: %@", filePath);
+}];
+[downloadTask resume];
+```
+
+#### Creating an Upload Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
+NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"Success: %@ %@", response, responseObject);
+    }
+}];
+[uploadTask resume];
+```
+
+#### Creating an Upload Task for a Multi-Part Request, with Progress
+
+```objective-c
+NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
+        [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
+    } error:nil];
+
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
+
+NSURLSessionUploadTask *uploadTask;
+uploadTask = [manager
+              uploadTaskWithStreamedRequest:request
+              progress:^(NSProgress * _Nonnull uploadProgress) {
+                  // This is not called back on the main queue.
+                  // You are responsible for dispatching to the main queue for UI updates
+                  dispatch_async(dispatch_get_main_queue(), ^{
+                      //Update the progress view
+                      [progressView setProgress:uploadProgress.fractionCompleted];
+                  });
+              }
+              completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
+                  if (error) {
+                      NSLog(@"Error: %@", error);
+                  } else {
+                      NSLog(@"%@ %@", response, responseObject);
+                  }
+              }];
+
+[uploadTask resume];
+```
+
+#### Creating a Data Task
+
+```objective-c
+NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
+AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
+
+NSURL *URL = [NSURL URLWithString:@"http://httpbin.org/get"];
+NSURLRequest *request = [NSURLRequest requestWithURL:URL];
+
+NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
+    if (error) {
+        NSLog(@"Error: %@", error);
+    } else {
+        NSLog(@"%@ %@", response, responseObject);
+    }
+}];
+[dataTask resume];
+```
+
+---
+
+### Request Serialization
+
+Request serializers create requests from URL strings, encoding parameters as either a query string or HTTP body.
+
+```objective-c
+NSString *URLString = @"http://example.com";
+NSDictionary *parameters = @{@"foo": @"bar", @"baz": @[@1, @2, @3]};
+```
+
+#### Query String Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:URLString parameters:parameters error:nil];
+```
+
+    GET http://example.com?foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### URL Form Parameter Encoding
+
+```objective-c
+[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
+```
+
+    POST http://example.com/
+    Content-Type: application/x-www-form-urlencoded
+
+    foo=bar&baz[]=1&baz[]=2&baz[]=3
+
+#### JSON Parameter Encoding
+
+```objective-c
+[[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
+```
+
+    POST http://example.com/
+    Content-Type: application/json
+
+    {"foo": "bar", "baz": [1,2,3]}
+
+---
+
+### Network Reachability Manager
+
+`AFNetworkReachabilityManager` monitors the reachability of domains, and addresses for both WWAN and WiFi network interfaces.
+
+* Do not use Reachability to determine if the original request should be sent.
+	* You should try to send it.
+* You can use Reachability to determine when a request should be automatically retried.
+	* Although it may still fail, a Reachability notification that the connectivity is available is a good time to retry something.
+* Network reachability is a useful tool for determining why a request might have failed.
+	* After a network request has failed, telling the user they're offline is better than giving them a more technical but accurate error, such as "request timed out."
+
+See also [WWDC 2012 session 706, "Networking Best Practices."](https://developer.apple.com/videos/play/wwdc2012-706/).
+
+#### Shared Network Reachability
+
+```objective-c
+[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
+    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));
+}];
+
+[[AFNetworkReachabilityManager sharedManager] startMonitoring];
+```
+
+---
+
+### Security Policy
+
+`AFSecurityPolicy` evaluates server trust against pinned X.509 certificates and public keys over secure connections.
+
+Adding pinned SSL certificates to your app helps prevent man-in-the-middle attacks and other vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged to route all communication over an HTTPS connection with SSL pinning configured and enabled.
+
+#### Allowing Invalid SSL Certificates
+
+```objective-c
+AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
+manager.securityPolicy.allowInvalidCertificates = YES; // not recommended for production
+```
+
+---
+
+## Unit Tests
+
+AFNetworking includes a suite of unit tests within the Tests subdirectory. These tests can be run simply be executed the test action on the platform framework you would like to test.

+/**
+ `AFNetworkActivityIndicatorManager` manages the state of the network activity indicator in the status bar. When enabled, it will listen for notifications indicating that a session task has started or finished, and start or stop animating the indicator accordingly. The number of active requests is incremented and decremented much like a stack or a semaphore, and the activity indicator will animate so long as that number is greater than zero.
+
+ You should enable the shared instance of `AFNetworkActivityIndicatorManager` when your application finishes launching. In `AppDelegate application:didFinishLaunchingWithOptions:` you can do so with the following code:
+
+    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
+
+ By setting `enabled` to `YES` for `sharedManager`, the network activity indicator will show and hide automatically as requests start and finish. You should not ever need to call `incrementActivityCount` or `decrementActivityCount` yourself.
+
+ See the Apple Human Interface Guidelines section about the Network Activity Indicator for more information:
+ http://developer.apple.com/library/iOS/#documentation/UserExperience/Conceptual/MobileHIG/UIElementGuidelines/UIElementGuidelines.html#//apple_ref/doc/uid/TP40006556-CH13-SW44

+ Asynchronously downloads an image from the specified URL request, and sets it as the image for the specified state once the request is finished. Any previous image request for the receiver will be cancelled.
+
+ If the image is cached locally, the image is set immediately, otherwise the specified placeholder image will be set immediately, and then the remote image will be set once the request is finished.
+
+ If a success block is specified, it is the responsibility of the block to set the image of the button before returning. If no success block is specified, the default behavior of setting the image with `setBackgroundImage:forState:` is applied.
+
+ @param state The control state.
+ @param urlRequest The URL request used for the image request.
+ @param placeholderImage The background image to be set initially, until the background image request finishes. If `nil`, the button will not change its background image until the background image request finishes.
+ @param success A block to be executed when the image data task finishes successfully. This block has no return value and takes three arguments: the request sent from the client, the response received from the server, and the image created from the response data of request. If the image was returned from cache, the response parameter will be `nil`.
+ @param failure A block object to be executed when the image data task finishes unsuccessfully, or that finishes successfully. This block has no return value and takes three arguments: the request sent from the client, the response received from the server, and the error object describing the network or parsing error that occurred.

+# BRPickerView
+
+BRPickerView 封装的是iOS中常用的选择器组件，主要包括：**`BRDatePickerView`** 日期选择器（支持年月日、年月等15种日期样式选择，支持设置星期、至今等）、**`BRTextPickerView`** 文本选择器（支持单列、多列、省市区、省市、省、自定义多级联动选择）。支持自定义主题样式，适配深色模式，支持将选择器组件添加到指定容器视图。
+
+⚠️【特别说明】
+
+>- 从 `V2.9.0` 版本起，新增了`BRTextPickerView` 组件，用于替代 `BRAddressPickerView` 和 `BRStringPickerView` 两个旧组件（目前这两个旧组件做了兼容，可以继续使用，后续会废弃掉，建议使用 `BRTextPickerView` 新组件进行替代）
+>- `V2.8.8`之前老版本，在iOS18+系统上，会因 `maskView` 命名出现崩溃问题，请及时升级到最新版本。
+>- 如果不能找到最新版本，请先执行一下 `pod repo update ` 更新本地仓库，使 CocoaPods 能识别最新可用的库版本。

+
+# 安装
+
+#### CocoaPods
+
+1. 在 Podfile 中添加 `pod 'BRPickerView'`
+2. 执行 `pod install` 或 `pod update` 
+3. 导入头文件 ` #import <BRPickerView.h>`
+
+>安装说明：
+>
+>**pod 'BRPickerView'** ：默认是安装全部组件（包含：`BRDatePickerView` 、 `BRTextPickerView` ，和废弃的`BRAddressPickerView` 、`BRStringPickerView` 组件），等价于：`pod 'BRPickerView/All'`
+>
+>**pod 'BRPickerView/Default'** ：仅安装`BRDatePickerView` 和 `BRTextPickerView` 组件
+
+
+#### 手动导入
+
+1. 将与 `README.md` 同级目录下的 `BRPickerView` 文件夹拽入项目中
+
+2. 导入头文件 ` #import "BRPickerView.h"`。
+
+
+# 系统要求
+
+- iOS 9.0+
+- ARC
+
+# 使用
+
+### 时间选择器：`BRDatePickerView`
+
+查看 BRDatePickerView.h 头文件，里面提供了两种使用方式，参见源码。
+
+```objective-c

+NSArray *unitArr = @[@"年", @"月", @"日"];
+for (NSInteger i = 0; i < unitArr.count; i++) {
+    CGFloat width = SCREEN_WIDTH / unitArr.count;
+    CGFloat orginX = i * (SCREEN_WIDTH / unitArr.count);
+    UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(orginX, 0, width, 36)];
+    label.backgroundColor = [UIColor clearColor];
+    label.textAlignment = NSTextAlignmentCenter;
+    label.font = [UIFont systemFontOfSize:16.0f];

+
+
+
+### 文本选择器：`BRTextPickerView`
+
+查看 BRTextPickerView.h 头文件，提供了三种类型：
+
+```objective-c
+/// 文本选择器类型
+typedef NS_ENUM(NSInteger, BRTextPickerMode) {
+    /** 单列选择器 */
+    BRTextPickerComponentSingle,
+    /** 多列选择器 */
+    BRTextPickerComponentMulti,
+    /** 多列联动选择器 */
+    BRTextPickerComponentCascade
+};
+```
+
+#### 1. 单列文本选择器
+
+- 使用示例：
+
+```objective-c
+/// 单列文本选择器
+BRTextPickerView *textPickerView = [[BRTextPickerView alloc]initWithPickerMode:BRTextPickerComponentSingle];
+textPickerView.title = @"学历";
+// 设置数据源
+textPickerView.dataSourceArr = @[@"大专以下", @"大专", @"本科", @"硕士", @"博士", @"博士后"];
+textPickerView.selectIndex = self.mySelectIndex;
+textPickerView.singleResultBlock = ^(BRTextModel * _Nullable model, NSInteger index) {
+  	NSLog(@"选择的值：%@", model.text);
+    self.mySelectIndex = index;
+    textField.text = model.text;
+};
+[textPickerView show];
+```
+
+- 设置数据源有3种方式
+
+```objective-c
+// 方式1：传字符串数组
+textPickerView.dataSourceArr = @[@"大专以下", @"大专", @"本科", @"硕士", @"博士", @"博士后"];
+```
+
+```objective-c
+// 方式2：直接传入 plist 文件名（可以将上面的字符串数组放到本地plist文件中，如：education_data.plist）
+textPickerView.fileName = @"education_data.plist";
+```
+
+```objective-c
+// 方式3：传入一维模型数组(NSArray <BRTextModel *>*)
+NSArray *dataArr = @[@{@"code": @"1", @"text": @"大专以下"},
+                     @{@"code": @"2", @"text": @"大专"},
+                     @{@"code": @"3", @"text": @"本科"},
+                     @{@"code": @"4", @"text": @"硕士"},
+                     @{@"code": @"5", @"text": @"博士"},
+                     @{@"code": @"6", @"text": @"博士后"}];
+// 将上面数组 转为 模型数组（组件内封装的工具方法）
+NSArray<BRTextModel *> *modelArr = [NSArray br_modelArrayWithJson:dataArr mapper:nil];
+textPickerView.dataSourceArr = modelArr;
+```
+
+说明：当字典key 与 BRTextModel模型的属性不匹配时，需要指定模型属性与字典key的映射关系
+
+```objective-c
+/// 单列文本选择器
+BRTextPickerView *textPickerView = [[BRTextPickerView alloc]initWithPickerMode:BRTextPickerComponentSingle];
+textPickerView.title = @"融资情况";
+// 方式3：传入一维模型数组(NSArray <BRTextModel *>*)
+NSArray *dataArr = @[@{@"key": @"1001", @"value": @"无融资", @"remark": @""},
+                     @{@"key": @"2001", @"value": @"天使轮", @"remark": @""},
+                     @{@"key": @"3001", @"value": @"A轮", @"remark": @""},
+                     @{@"key": @"4001", @"value": @"B轮", @"remark": @""},
+                     @{@"key": @"5001", @"value": @"C轮以后", @"remark": @""},
+                     @{@"key": @"6001", @"value": @"已上市", @"remark": @""}];
+// 指定 BRTextModel模型的属性 与 字典key 的映射关系
+NSDictionary *mapper = @{ @"code": @"key", @"text": @"value", @"extras": @"remark" };
+// 将上面数组 转为 模型数组（组件内封装的工具方法）
+NSArray<BRTextModel *> *modelArr = [NSArray br_modelArrayWithJson:dataArr mapper:mapper];
+textPickerView.dataSourceArr = modelArr;
+textPickerView.singleResultBlock = ^(BRTextModel * _Nullable model, NSInteger index) {
+  	NSLog(@"选择的值：%@", model.text);
+};
+[textPickerView show];
+```

+
+
+
+#### 2. 多列文本选择器
+
+- 使用示例：
+
+```objective-c
+/// 多列文本选择器
+BRTextPickerView *textPickerView = [[BRTextPickerView alloc]initWithPickerMode:BRTextPickerComponentMulti];
+textPickerView.title = @"多列文本选择器";
+// 设置数据源
+textPickerView.dataSourceArr = @[@[@"语文", @"数学", @"英语"], @[@"优秀", @"良好"]];
+textPickerView.selectIndexs = self.mySelectIndexs;
+textPickerView.multiResultBlock = ^(NSArray<BRTextModel *> * _Nullable models, NSArray<NSNumber *> * _Nullable indexs) {
+		self.mySelectIndexs = indexs;
+    // 将模型数组元素的 text 属性值，通过分隔符-连接成字符串（组件内封装的工具方法）
+    NSString *selectText = [models br_joinText:@"-"];
+    NSLog(@"选择的结果：%@", selectText);
+};
+[textPickerView show];
+```
+
+- 多列文本选择器设置数据源同单列一样，也有3种方式：
+
+```objective-c
+// 方式1：多维字符串数组
+textPickerView.dataSourceArr = @[@[@"语文", @"数学", @"英语"], @[@"优秀", @"良好"]];
+```
+
+```objective-c
+// 方式2：直接传入 plist 文件名（可以将上面的数组放到本地plist文件中，如：grade_level_data.plist）
+textPickerView.fileName = @"grade_level_data.plist";
+```
+
+```objective-c
+// 方式3：传入多维模型数组
+NSArray *subjectDataArr = @[@{@"subject_id": @"11", @"subject": @"语文"}, @{@"subject_id": @"12", @"subject": @"数学"}, @{@"subject_id": @"13", @"subject": @"英语"}];
+NSArray *gradeDataArr = @[@{@"grade_id": @"1", @"grade": @"优秀"}, @{@"grade_id": @"2", @"grade": @"良好"}];
+// 将上面数组 转为 模型数组（组件内封装的工具方法）
+NSArray *subjectModelArr = [NSArray br_modelArrayWithJson:subjectDataArr mapper:@{ @"code": @"subject_id", @"text": @"subject" }];
+NSArray *gradeModelArr = [NSArray br_modelArrayWithJson:gradeDataArr mapper:@{ @"code": @"grade_id", @"text": @"grade" }];
+textPickerView.dataSourceArr = @[subjectModelArr, gradeModelArr];
+```
+
+- 另外还可以设置更多自定义样式
+
+```objective-c
+/// 多列文本选择器
+BRTextPickerView *textPickerView = [[BRTextPickerView alloc]initWithPickerMode:BRTextPickerComponentMulti];
+textPickerView.title = @"自定义多列字符串";
+textPickerView.dataSourceArr = @[@[@"01", @"02", @"03", @"04", @"05", @"06", @"07", @"08", @"09", @"10", @"11", @"12"], @[@"00", @"10", @"20", @"30", @"40", @"50"]];
+textPickerView.selectIndexs = self.mySelectIndexs;
+textPickerView.multiResultBlock = ^(NSArray<BRTextModel *> * _Nullable models, NSArray<NSNumber *> * _Nullable indexs) {
+  	self.mySelectIndexs = indexs;
+    // 将模型数组元素的 text 属性值，通过:分隔符 连接成字符串（组件内封装的工具方法）
+    NSString *selectText = [models br_joinText:@":"];
+    NSLog(@"选择的结果：%@", selectText);
+};
+
+// 设置自定义样式
+BRPickerStyle *customStyle = [[BRPickerStyle alloc]init];
+// 设置 picker 的列宽
+customStyle.columnWidth = 30;
+// 设置 picker 的列间隔
+customStyle.columnSpacing = 60;
+// 设置圆角矩形背景
+// 方式1：使用系统自带样式，保留iOS14之后系统默认的圆角样式。
+customStyle.clearPickerNewStyle = NO;
+// 方式2：可以使用UIView自定义一个圆角矩形视图rectView，并添加到 alertView 上也能实现同样的效果（[textPickerView.alertView addSubview:rectView];）
+// 设置选择器中间选中行的样式
+customStyle.selectRowTextFont = [UIFont boldSystemFontOfSize:20.0f];
+customStyle.selectRowTextColor = [UIColor blueColor];
+textPickerView.pickerStyle = customStyle;
+
+[textPickerView show];
+```

+
+
+
+#### 3. 多列联动文本选择器
+
+- 使用示例：
+
+```objective-c
+/// 多列联动文本选择器
+BRTextPickerView *textPickerView = [[BRTextPickerView alloc]initWithPickerMode:BRTextPickerComponentCascade];
+textPickerView.title = @"多列联动文本选择器";
+NSArray *dataArr = @[
+    @{
+        @"text" : @"浙江省",
+        @"children" : @[
+            @{ @"text": @"杭州市", @"children": @[@{ @"text": @"西湖区" }, @{ @"text": @"滨江区" }] },
+            @{ @"text": @"宁波市", @"children": @[@{ @"text": @"海曙区" }, @{ @"text": @"江北区" }] },
+            @{ @"text": @"温州市", @"children": @[@{ @"text": @"鹿城区" }, @{ @"text": @"龙湾区" }] }
+      ]
+    },
+    @{
+        @"text" : @"江苏省",
+        @"children" : @[
+            @{ @"text": @"南京市", @"children": @[@{ @"text": @"玄武区" }, @{ @"text": @"秦淮区" }] },
+            @{ @"text": @"苏州市", @"children": @[@{ @"text": @"虎丘区" }, @{ @"text": @"吴中区" }] }
+      ]
+    },
+    @{
+        @"text" : @"辽宁省",
+        @"children" : @[
+            @{ @"text": @"沈阳市", @"children": @[@{ @"text": @"沈河区" }, @{ @"text": @"和平区" }] },
+            @{ @"text": @"大连市", @"children": @[@{ @"text": @"中山区" }, @{ @"text": @"金州区" }] }
+      ]
+    }
+];
+// 设置数据源：传树状结构模型数组(NSArray <BRTextModel *>*)
+textPickerView.dataSourceArr = [NSArray br_modelArrayWithJson:dataArr mapper:nil];
+textPickerView.selectIndexs = self.mySelectIndexs;
+textPickerView.multiResultBlock = ^(NSArray<BRTextModel *> * _Nullable models, NSArray<NSNumber *> * _Nullable indexs) {
+    self.mySelectIndexs = indexs;
+  	// 将模型数组元素的 text 属性值，通过-分隔符 连接成字符串（组件内封装的工具方法）
+    NSString *selectText = [models br_joinText:@"-"];
+    NSLog(@"选择的结果：%@", selectText);
+};
+[textPickerView show];
+```
+
+
+
+- 实现省、市、区/县选择（使用本地数据源：region_tree_data.json）
+
+```objective-c
+// 地区
+BRTextPickerView *textPickerView = [[BRTextPickerView alloc]initWithPickerMode:BRTextPickerComponentCascade];
+textPickerView.title = @"请选择地区";
+// 设置数据源：传入本地json文件名（可以下载Demo中的 region_tree_data.json 文件放到自己的项目中，该数据源来源于高德地图最新数据）
+textPickerView.fileName = @"region_tree_data.json";
+// 设置选择器显示的列数(即层级数)，默认是根据数据源层级动态计算显示。如：设置1则只显示前1列数据（即只显示省）；设置2则只显示前2列数据（即只显示省、市）；设置3则只显示前3列数据（即显示省、市、区）
+textPickerView.showColumnNum = 3;
+textPickerView.selectIndexs = self.addressSelectIndexs;
+textPickerView.multiResultBlock = ^(NSArray<BRTextModel *> * _Nullable models, NSArray<NSNumber *> * _Nullable indexs) {
+    self.addressSelectIndexs = indexs;
+    // 将模型数组元素的 text 属性值，通过-分隔符 连接成字符串（组件内封装的工具方法）
+    NSString *selectText = [models br_joinText:@"-"];
+    NSLog(@"选择的结果：%@", selectText);
+    textField.text = selectText;
+};
+[textPickerView show];

+
+```objective-c
+/// 扩展一：添加选择器到指定容器视图上
+/// 应用场景：可将中间的滚轮选择器 pickerView 视图（不包含蒙层及标题栏）添加到任何自定义视图上（会自动填满容器视图），也方便自定义更多的弹框样式
+/// 补充说明：如果是自定义确定按钮，需要回调默认选择的值：只需在自定义确定按钮的点击事件方法里执行一下 doneBlock 回调（目的是去触发组件内部执行 resultBlock 回调，进而回调默认选择的值）
+/// @param view 容器视图

+CircleProgressBar
+=================
+
+Circle Progress Bar iOS Control.
+
+Require iOS 7.0+ or tvOS 9.0+
+
+![CircleProgressBar Screenshot-iOS-Example](https://raw.githubusercontent.com/Eclair/CircleProgressBar/master/Screenshots/ios-screen01.png)
+![CircleProgressBar Screenshot-iOS-Example2](https://raw.githubusercontent.com/Eclair/CircleProgressBar/master/Screenshots/ios-screen02.png)
+
+Installation
+============
+
+You can install this control in two ways:
+
+1. Using CocoaPods:
+
+```ruby
+pod 'CircleProgressBar', '~> 0.32’
+```
+
+2. Manually:
+
+  Download source from this repository and copy CircleProgressBarDemo/CircleProgressBar folder to your project.
+
+	Don't forget to add _*UIKit*_ and _*QuartzCore*_ frameworks to your project.
+
+How to use
+==========
+
+_NOTE: If you installed this control manually - please be sure that you've added UIKit and QuartzCore frameworks to your project._
+
+_NOTE: If you're using rectangular view for CircleProgressBar control instead of square, ProgressBar will fit available area and will be drawn in center of it._
+
+You can simply add UIView in Interface Builder to your controller and change it's class to "CircleProgressBar" (overridden _initWithCoder_ method will be called) or create CircleProgressBar programmatically using _init_ or _initWithFrame_ methods.
+
+Using Interface Builder you'll take advantage of Xcode 6 new live rendering feature to customize control according to your needs on the fly (will be explained below in "Customization" section).
+
+To change progress, simply call "setProgress:animated:" method of CircleProgressBar instance:
+
+```objective-c
+[_circleProgressBar setProgress:(CGFloat)progress animated:(BOOL)animated];
+```
+
+or "setProgress:animated:duration:" method to define custom animation time:
+
+```objective-c
+[_circleProgressBar setProgress:(CGFloat)progress animated:(BOOL)animated duration:(CGFloat)duration];
+```
+
+To check if there is ongoing animation use `isAnimating` property.
+To stop an ongoing animation, you can use `stopAnimation` method. In this case it will set the progress to animation end value:
+
+```objective-c
+[_circleProgressBar stopAnimation];
+```
+
+Customization
+=============
+
+CircleProgressBar provides many customization properties:
+
+```objective-c
+// Progress Bar Customization
+@property (nonatomic) CGFloat progressBarWidth;
+@property (nonatomic) UIColor *progressBarProgressColor;
+@property (nonatomic) UIColor *progressBarTrackColor;
+@property (nonatomic) CGFloat startAngle;
+
+// Hint View Customization (inside progress bar)
+@property (nonatomic) BOOL hintHidden;
+@property (nonatomic) CGFloat hintViewSpacing;
+@property (nonatomic) UIColor *hintViewBackgroundColor;
+@property (nonatomic) UIFont *hintTextFont;
+@property (nonatomic) UIColor *hintTextColor;
+```
+
+Using these customization properties you can define Progress Bar's width, color of filled part, color of empty part, Progress Bar's start angle, Hint View's spacing (between progress bar and hint view), background color, hint text color and hint text font.
+
+If you want to hide HintView you can simply set hintHidden property to NO.
+
+To customize text inside HintView you can simply set TextGenerationBlock:
+
+```objective-c
+- (void)setHintTextGenerationBlock:(StringGenerationBlock)generationBlock;
+```
+
+For example this way:
+
+```objective-c
+[_circleProgressBar setHintTextGenerationBlock:^NSString *(CGFloat progress) {
+  return [NSString stringWithFormat:@"%.0f / 255", progress * 255];
+}];
+```
+
+If you want to use NSAttributedString you can set instead HintAttributedGenerationBlock:
+
+```objective-c
+- (void)setHintAttributedGenerationBlock:(AttributedStringGenerationBlock)generationBlock;
+```
+
+If you using Interface Builder, you can take an advantage of Xcode 6 live render with IBDesignable and IBInspectable features to customize control:

+# FDFullscreenPopGesture
+An UINavigationController's category to enable fullscreen pop gesture in an iOS7+ system style with AOP.
+
+# Overview
+
+![snapshot](https://raw.githubusercontent.com/forkingdog/FDFullscreenPopGesture/master/Snapshots/snapshot0.gif)
+
+这个扩展来自 @J_雨 同学的这个很天才的思路，他的文章地址：[http://www.jianshu.com/p/d39f7d22db6c](http://www.jianshu.com/p/d39f7d22db6c)
+
+# Usage
+
+**AOP**, just add 2 files and **no need** for any setups, all navigation controllers will be able to use fullscreen pop gesture automatically.  
+
+To disable this pop gesture of a navigation controller:  
+
+``` objc
+navigationController.fd_fullscreenPopGestureRecognizer.enabled = NO;
+```
+
+To disable this pop gesture of a view controller:  
+
+``` objc
+viewController.fd_interactivePopDisabled = YES;
+```
+
+Require at least iOS **7.0**.
+
+# View Controller Based Navigation Bar Appearance
+
+It handles navigation bar transition properly when using fullscreen gesture to push or pop a view controller:  
+
+- with bar -> without bar
+- without bar -> with bar
+- without bar -> without bar
+
+![snapshot with bar states](https://raw.githubusercontent.com/forkingdog/FDFullscreenPopGesture/master/Snapshots/snapshot1.gif)
+
+This opmiziation is enabled by default, from now on you don't need to call **UINavigationController**'s `-setNavigationBarHidden:animated:` method, instead, use view controller's specific API to hide its bar:  
+
+``` objc
+- (void)viewDidLoad {
+    [super viewDidLoad];
+    self.fd_prefersNavigationBarHidden = NO;
+}
+```
+
+And this property is **YES** by default.
+
+# Installation
+
+Use cocoapods  
+
+``` ruby
+pod 'FDFullscreenPopGesture', '1.1'
+```
+# Release Notes
+
+**1.1** - View controller based navigation bar appearance and transition.  
+**1.0** - Fullscreen pop gesture.

+# FMDB v2.7
+<!--[![Platform](https://img.shields.io/cocoapods/p/FMDB.svg?style=flat)](http://cocoadocs.org/docsets/Alamofire)-->
+[![CocoaPods Compatible](https://img.shields.io/cocoapods/v/FMDB.svg)](https://img.shields.io/cocoapods/v/FMDB.svg)
+[![Carthage Compatible](https://img.shields.io/badge/Carthage-compatible-4BC51D.svg?style=flat)](https://github.com/Carthage/Carthage)
+
+This is an Objective-C wrapper around [SQLite](https://sqlite.org/).
+
+## The FMDB Mailing List:
+https://groups.google.com/group/fmdb
+
+## Read the SQLite FAQ:
+https://www.sqlite.org/faq.html
+
+Since FMDB is built on top of SQLite, you're going to want to read this page top to bottom at least once.  And while you're there, make sure to bookmark the SQLite Documentation page: https://www.sqlite.org/docs.html
+
+## Contributing
+Do you have an awesome idea that deserves to be in FMDB?  You might consider pinging ccgus first to make sure he hasn't already ruled it out for some reason.  Otherwise pull requests are great, and make sure you stick to the local coding conventions.  However, please be patient and if you haven't heard anything from ccgus for a week or more, you might want to send a note asking what's up.
+
+## Installing
+
+### CocoaPods
+
+FMDB can be installed using [CocoaPods](https://cocoapods.org/).
+
+If you haven't done so already, you might want to initialize the project, to have it produce a `Podfile` template for you:
+
+```
+$ pod init
+```
+
+Then, edit the `Podfile`, adding `FMDB`:
+
+```ruby
+# Uncomment the next line to define a global platform for your project
+# platform :ios, '12.0'
+
+target 'MyApp' do
+    # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
+    use_frameworks!
+
+    # Pods for MyApp2
+
+    pod 'FMDB'
+    # pod 'FMDB/FTS'   # FMDB with FTS
+    # pod 'FMDB/standalone'   # FMDB with latest SQLite amalgamation source
+    # pod 'FMDB/standalone/FTS'   # FMDB with latest SQLite amalgamation source and FTS
+    # pod 'FMDB/SQLCipher'   # FMDB with SQLCipher
+end
+```
+
+Then install the pods:
+
+```
+$ pod install
+```
+
+Then open the `.xcworkspace` rather than the `.xcodeproj`.
+
+For more information on Cocoapods visit https://cocoapods.org.
+
+**If using FMDB with [SQLCipher](https://www.zetetic.net/sqlcipher/) you must use the FMDB/SQLCipher subspec. The FMDB/SQLCipher subspec declares SQLCipher as a dependency, allowing FMDB to be compiled with the `-DSQLITE_HAS_CODEC` flag.**
+
+### Carthage
+
+Once you make sure you have [the latest version of Carthage](https://github.com/Carthage/Carthage/releases), you can open up a command line terminal, navigate to your project's main directory, and then do the following commands:
+
+```
+$ echo ' github "ccgus/fmdb" ' > ./Cartfile
+$ carthage update
+```
+
+You can then configure your project as outlined in Carthage's [Getting Started](https://github.com/Carthage/Carthage#getting-started) (i.e. for iOS, adding the framework to the "Link Binary with Libraries" in your target and adding the `copy-frameworks` script; in macOS, adding the framework to the list of "Embedded Binaries").
+
+### Swift Package Manager
+
+Declare FMDB as a package dependency.
+```swift
+.package(
+    name: "FMDB", 
+    url: "https://github.com/ccgus/fmdb", 
+    .upToNextMinor(from: "2.7.12")),
+```
+
+Use FMDB in target dependencies
+```swift
+.product(name: "FMDB", package: "FMDB")
+```
+
+## FMDB Class Reference:
+https://ccgus.github.io/fmdb/html/index.html
+
+## Automatic Reference Counting (ARC) or Manual Memory Management?
+You can use either style in your Cocoa project.  FMDB will figure out which you are using at compile time and do the right thing.
+
+## What's New in FMDB 2.7
+
+FMDB 2.7 attempts to support a more natural interface. This represents a fairly significant change for Swift developers (audited for nullability; shifted to properties in external interfaces where possible rather than methods; etc.). For Objective-C developers, this should be a fairly seamless transition (unless you were using the ivars that were previously exposed in the public interface, which you shouldn't have been doing, anyway!). 
+
+### Nullability and Swift Optionals
+
+FMDB 2.7 is largely the same as prior versions, but has been audited for nullability. For Objective-C users, this simply means that if you perform a static analysis of your FMDB-based project, you may receive more meaningful warnings as you review your project, but there are likely to be few, if any, changes necessary in your code.
+
+For Swift users, this nullability audit results in changes that are not entirely backward compatible with FMDB 2.6, but is a little more Swifty. Before FMDB was audited for nullability, Swift was forced to defensively assume that variables were optional, but the library now more accurately knows which properties and method parameters are optional, and which are not.
+
+This means, though, that Swift code written for FMDB 2.7 may require changes. For example, consider the following Swift 3/Swift 4 code for FMDB 2.6:
+
+```swift
+queue.inTransaction { db, rollback in
+    do {
+        guard let db == db else {
+            // handle error here
+            return
+        }
+
+        try db.executeUpdate("INSERT INTO foo (bar) VALUES (?)", values: [1])
+        try db.executeUpdate("INSERT INTO foo (bar) VALUES (?)", values: [2])
+    } catch {
+        rollback?.pointee = true
+    }
+}
+```
+
+Because FMDB 2.6 was not audited for nullability, Swift inferred that `db` and `rollback` were optionals. But, now, in FMDB 2.7, Swift now knows that, for example, neither `db` nor `rollback` above can be `nil`, so they are no longer optionals. Thus it becomes:
+
+```swift
+queue.inTransaction { db, rollback in
+    do {
+        try db.executeUpdate("INSERT INTO foo (bar) VALUES (?)", values: [1])
+        try db.executeUpdate("INSERT INTO foo (bar) VALUES (?)", values: [2])
+    } catch {
+        rollback.pointee = true
+    }
+}
+```
+
+### Custom Functions
+
+In the past, when writing custom functions, you would have to generally include your own `@autoreleasepool` block to avoid problems when writing functions that scanned through a large table. Now, FMDB will automatically wrap it in an autorelease pool, so you don't have to.
+
+Also, in the past, when retrieving the values passed to the function, you had to drop down to the SQLite C API and include your own `sqlite3_value_XXX` calls. There are now `FMDatabase` methods, `valueInt`, `valueString`, etc., so you can stay within Swift and/or Objective-C, without needing to call the C functions yourself. Likewise, when specifying the return values, you no longer need to call `sqlite3_result_XXX` C API, but rather you can use `FMDatabase` methods, `resultInt`, `resultString`, etc. There is a new `enum` for `valueType` called `SqliteValueType`, which can be used for checking the type of parameter passed to the custom function.
+
+Thus, you can do something like (as of Swift 3):
+
+```swift
+db.makeFunctionNamed("RemoveDiacritics", arguments: 1) { context, argc, argv in
+    guard db.valueType(argv[0]) == .text || db.valueType(argv[0]) == .null else {
+        db.resultError("Expected string parameter", context: context)
+        return
+    }
+
+    if let string = db.valueString(argv[0])?.folding(options: .diacriticInsensitive, locale: nil) {
+        db.resultString(string, context: context)
+    } else {
+        db.resultNull(context: context)
+    }
+}
+```
+
+And you can then use that function in your SQL (in this case, matching both "Jose" and "José"):
+
+```sql
+SELECT * FROM employees WHERE RemoveDiacritics(first_name) LIKE 'jose'
+```
+
+Note, the method `makeFunctionNamed:maximumArguments:withBlock:` has been renamed to `makeFunctionNamed:arguments:block:`, to more accurately reflect the functional intent of the second parameter.
+
+### API Changes
+
+In addition to the `makeFunctionNamed` noted above, there are a few other API changes. Specifically, 
+
+ - To become consistent with the rest of the API, the methods `objectForColumnName` and `UTF8StringForColumnName` have been renamed to `objectForColumn` and `UTF8StringForColumn`.
+
+ - Note, the `objectForColumn` (and the associted subscript operator) now returns `nil` if an invalid column name/index is passed to it. It used to return `NSNull`.
+
+ - To avoid confusion with `FMDatabaseQueue` method `inTransaction`, which performs transactions, the `FMDatabase` method to determine whether you are in a transaction or not, `inTransaction`, has been replaced with a read-only property, `isInTransaction`. 
+
+ - Several functions have been converted to properties, namely, `databasePath`, `maxBusyRetryTimeInterval`, `shouldCacheStatements`, `sqliteHandle`, `hasOpenResultSets`, `lastInsertRowId`, `changes`, `goodConnection`, `columnCount`, `resultDictionary`, `applicationID`, `applicationIDString`, `userVersion`, `countOfCheckedInDatabases`, `countOfCheckedOutDatabases`, and `countOfOpenDatabases`. For Objective-C users, this has little material impact, but for Swift users, it results in a slightly more natural interface. Note: For Objective-C developers, previously versions of FMDB exposed many ivars (but we hope you weren't using them directly, anyway!), but the implmentation details for these are no longer exposed.
+
+### URL Methods
+
+In keeping with Apple's shift from paths to URLs, there are now `NSURL` renditions of the various `init` methods, previously only accepting paths. 
+
+## Usage
+There are three main classes in FMDB:
+
+1. `FMDatabase` - Represents a single SQLite database.  Used for executing SQL statements.
+2. `FMResultSet` - Represents the results of executing a query on an `FMDatabase`.
+3. `FMDatabaseQueue` - If you're wanting to perform queries and updates on multiple threads, you'll want to use this class.  It's described in the "Thread Safety" section below.
+
+### Database Creation
+An `FMDatabase` is created with a path to a SQLite database file.  This path can be one of these three:
+
+1. A file system path.  The file does not have to exist on disk.  If it does not exist, it is created for you.
+2. An empty string (`@""`).  An empty database is created at a temporary location.  This database is deleted when the `FMDatabase` connection is closed.
+3. `NULL`.  An in-memory database is created.  This database will be destroyed when the `FMDatabase` connection is closed.
+
+(For more information on temporary and in-memory databases, read the sqlite documentation on the subject: https://www.sqlite.org/inmemorydb.html)
+
+```objc
+NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:@"tmp.db"];
+FMDatabase *db = [FMDatabase databaseWithPath:path];
+```
+
+### Opening
+
+Before you can interact with the database, it must be opened.  Opening fails if there are insufficient resources or permissions to open and/or create the database.
+
+```objc
+if (![db open]) {
+    // [db release];   // uncomment this line in manual referencing code; in ARC, this is not necessary/permitted
+    db = nil;
+    return;
+}
+```
+
+### Executing Updates
+
+Any sort of SQL statement which is not a `SELECT` statement qualifies as an update.  This includes `CREATE`, `UPDATE`, `INSERT`, `ALTER`, `COMMIT`, `BEGIN`, `DETACH`, `DELETE`, `DROP`, `END`, `EXPLAIN`, `VACUUM`, and `REPLACE` statements (plus many more).  Basically, if your SQL statement does not begin with `SELECT`, it is an update statement.
+
+Executing updates returns a single value, a `BOOL`.  A return value of `YES` means the update was successfully executed, and a return value of `NO` means that some error was encountered.  You may invoke the `-lastErrorMessage` and `-lastErrorCode` methods to retrieve more information.
+
+### Executing Queries
+
+A `SELECT` statement is a query and is executed via one of the `-executeQuery...` methods.
+
+Executing queries returns an `FMResultSet` object if successful, and `nil` upon failure.  You should use the `-lastErrorMessage` and `-lastErrorCode` methods to determine why a query failed.
+
+In order to iterate through the results of your query, you use a `while()` loop.  You also need to "step" from one record to the other.  With FMDB, the easiest way to do that is like this:
+
+```objc
+FMResultSet *s = [db executeQuery:@"SELECT * FROM myTable"];
+while ([s next]) {
+    //retrieve values for each record
+}
+```
+
+You must always invoke `-[FMResultSet next]` before attempting to access the values returned in a query, even if you're only expecting one:
+
+```objc
+FMResultSet *s = [db executeQuery:@"SELECT COUNT(*) FROM myTable"];
+if ([s next]) {
+    int totalCount = [s intForColumnIndex:0];
+}
+[s close];  // Call the -close method on the FMResultSet if you cannot confirm whether the result set is exhausted.
+```
+
+`FMResultSet` has many methods to retrieve data in an appropriate format:
+
+- `intForColumn:`
+- `longForColumn:`
+- `longLongIntForColumn:`
+- `boolForColumn:`
+- `doubleForColumn:`
+- `stringForColumn:`
+- `dateForColumn:`
+- `dataForColumn:`
+- `dataNoCopyForColumn:`
+- `UTF8StringForColumn:`
+- `objectForColumn:`
+
+Each of these methods also has a `{type}ForColumnIndex:` variant that is used to retrieve the data based on the position of the column in the results, as opposed to the column's name.
+
+Typically, there's no need to `-close` an `FMResultSet` yourself, since that happens when either the result set is exhausted. However, if you only pull out a single request or any other number of requests which don't exhaust the result set, you will need to call the `-close` method on the `FMResultSet`.
+
+### Closing
+
+When you have finished executing queries and updates on the database, you should `-close` the `FMDatabase` connection so that SQLite will relinquish any resources it has acquired during the course of its operation.
+
+```objc
+[db close];
+```
+
+### Transactions
+
+`FMDatabase` can begin and commit a transaction by invoking one of the appropriate methods or executing a begin/end transaction statement.
+
+### Multiple Statements and Batch Stuff
+
+You can use `FMDatabase`'s executeStatements:withResultBlock: to do multiple statements in a string:
+
+```objc
+NSString *sql = @"create table bulktest1 (id integer primary key autoincrement, x text);"
+                 "create table bulktest2 (id integer primary key autoincrement, y text);"
+                 "create table bulktest3 (id integer primary key autoincrement, z text);"
+                 "insert into bulktest1 (x) values ('XXX');"
+                 "insert into bulktest2 (y) values ('YYY');"
+                 "insert into bulktest3 (z) values ('ZZZ');";
+
+success = [db executeStatements:sql];
+
+sql = @"select count(*) as count from bulktest1;"
+       "select count(*) as count from bulktest2;"
+       "select count(*) as count from bulktest3;";
+
+success = [self.db executeStatements:sql withResultBlock:^int(NSDictionary *dictionary) {
+    NSInteger count = [dictionary[@"count"] integerValue];
+    XCTAssertEqual(count, 1, @"expected one record for dictionary %@", dictionary);
+    return 0;
+}];
+```
+
+### Data Sanitization
+
+When providing a SQL statement to FMDB, you should not attempt to "sanitize" any values before insertion.  Instead, you should use the standard SQLite binding syntax:
+
+```sql
+INSERT INTO myTable VALUES (?, ?, ?, ?)
+```
+
+The `?` character is recognized by SQLite as a placeholder for a value to be inserted.  The execution methods all accept a variable number of arguments (or a representation of those arguments, such as an `NSArray`, `NSDictionary`, or a `va_list`), which are properly escaped for you.
+
+And, to use that SQL with the `?` placeholders from Objective-C:
+
+```objc
+NSInteger identifier = 42;
+NSString *name = @"Liam O'Flaherty (\"the famous Irish author\")";
+NSDate *date = [NSDate date];
+NSString *comment = nil;
+
+BOOL success = [db executeUpdate:@"INSERT INTO authors (identifier, name, date, comment) VALUES (?, ?, ?, ?)", @(identifier), name, date, comment ?: [NSNull null]];
+if (!success) {
+    NSLog(@"error = %@", [db lastErrorMessage]);
+}
+```
+
+> **Note:** Fundamental data types, like the `NSInteger` variable `identifier`, should be as a `NSNumber` objects, achieved by using the `@` syntax, shown above. Or you can use the `[NSNumber numberWithInt:identifier]` syntax, too.
+>
+> Likewise, SQL `NULL` values should be inserted as `[NSNull null]`. For example, in the case of `comment` which might be `nil` (and is in this example), you can use the `comment ?: [NSNull null]` syntax, which will insert the string if `comment` is not `nil`, but will insert `[NSNull null]` if it is `nil`.
+
+In Swift, you would use `executeUpdate(values:)`, which not only is a concise Swift syntax, but also `throws` errors for proper error handling:
+
+```swift
+do {
+    let identifier = 42
+    let name = "Liam O'Flaherty (\"the famous Irish author\")"
+    let date = Date()
+    let comment: String? = nil
+
+    try db.executeUpdate("INSERT INTO authors (identifier, name, date, comment) VALUES (?, ?, ?, ?)", values: [identifier, name, date, comment ?? NSNull()])
+} catch {
+    print("error = \(error)")
+}
+```
+
+> **Note:** In Swift, you don't have to wrap fundamental numeric types like you do in Objective-C. But if you are going to insert an optional string, you would probably use the `comment ?? NSNull()` syntax (i.e., if it is `nil`, use `NSNull`, otherwise use the string).
+
+Alternatively, you may use named parameters syntax:
+
+```sql
+INSERT INTO authors (identifier, name, date, comment) VALUES (:identifier, :name, :date, :comment)
+```
+
+The parameters *must* start with a colon. SQLite itself supports other characters, but internally the dictionary keys are prefixed with a colon, do **not** include the colon in your dictionary keys.
+
+```objc
+NSDictionary *arguments = @{@"identifier": @(identifier), @"name": name, @"date": date, @"comment": comment ?: [NSNull null]};
+BOOL success = [db executeUpdate:@"INSERT INTO authors (identifier, name, date, comment) VALUES (:identifier, :name, :date, :comment)" withParameterDictionary:arguments];
+if (!success) {
+    NSLog(@"error = %@", [db lastErrorMessage]);
+}
+```
+
+The key point is that one should not use `NSString` method `stringWithFormat` to manually insert values into the SQL statement, itself. Nor should one Swift string interpolation to insert values into the SQL. Use `?` placeholders for values to be inserted into the database (or used in `WHERE` clauses in `SELECT` statements).
+
+<h2 id="threads">Using FMDatabaseQueue and Thread Safety.</h2>
+
+Using a single instance of `FMDatabase` from multiple threads at once is a bad idea.  It has always been OK to make a `FMDatabase` object *per thread*.  Just don't share a single instance across threads, and definitely not across multiple threads at the same time.  Bad things will eventually happen and you'll eventually get something to crash, or maybe get an exception, or maybe meteorites will fall out of the sky and hit your Mac Pro.  *This would suck*.
+
+**So don't instantiate a single `FMDatabase` object and use it across multiple threads.**
+
+Instead, use `FMDatabaseQueue`. Instantiate a single `FMDatabaseQueue` and use it across multiple threads. The `FMDatabaseQueue` object will synchronize and coordinate access across the multiple threads. Here's how to use it:
+
+First, make your queue.
+
+```objc
+FMDatabaseQueue *queue = [FMDatabaseQueue databaseQueueWithPath:aPath];
+```
+
+Then use it like so:
+
+
+```objc
+[queue inDatabase:^(FMDatabase *db) {
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", @1];
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", @2];
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", @3];
+
+    FMResultSet *rs = [db executeQuery:@"select * from foo"];
+    while ([rs next]) {
+        …
+    }
+}];
+```
+
+An easy way to wrap things up in a transaction can be done like this:
+
+```objc
+[queue inTransaction:^(FMDatabase *db, BOOL *rollback) {
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", @1];
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", @2];
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", @3];
+
+    if (whoopsSomethingWrongHappened) {
+        *rollback = YES;
+        return;
+    }
+
+    // etc ...
+}];
+```
+
+The Swift equivalent would be:
+
+```swift
+queue.inTransaction { db, rollback in
+    do {
+        try db.executeUpdate("INSERT INTO myTable VALUES (?)", values: [1])
+        try db.executeUpdate("INSERT INTO myTable VALUES (?)", values: [2])
+        try db.executeUpdate("INSERT INTO myTable VALUES (?)", values: [3])
+
+        if whoopsSomethingWrongHappened {
+            rollback.pointee = true
+            return
+        }
+
+        // etc ...
+    } catch {
+        rollback.pointee = true
+        print(error)
+    }
+}
+```
+
+(Note, as of Swift 3, use `pointee`. But in Swift 2.3, use `memory` rather than `pointee`.)
+
+`FMDatabaseQueue` will run the blocks on a serialized queue (hence the name of the class).  So if you call `FMDatabaseQueue`'s methods from multiple threads at the same time, they will be executed in the order they are received.  This way queries and updates won't step on each other's toes, and every one is happy.
+
+**Note:** The calls to `FMDatabaseQueue`'s methods are blocking.  So even though you are passing along blocks, they will **not** be run on another thread.
+
+## Making custom sqlite functions, based on blocks.
+
+You can do this!  For an example, look for `-makeFunctionNamed:` in main.m
+
+## Swift
+
+You can use FMDB in Swift projects too.
+
+To do this, you must:
+
+1. Copy the relevant `.m` and `.h` files from the FMDB `src` folder into your project.
+
+ You can copy all of them (which is easiest), or only the ones you need. Likely you will need [`FMDatabase`](https://ccgus.github.io/fmdb/html/Classes/FMDatabase.html) and [`FMResultSet`](https://ccgus.github.io/fmdb/html/Classes/FMResultSet.html) at a minimum. [`FMDatabaseAdditions`](https://ccgus.github.io/fmdb/html/Categories/FMDatabase+FMDatabaseAdditions.html) provides some very useful convenience methods, so you will likely want that, too. If you are doing multithreaded access to a database, [`FMDatabaseQueue`](https://ccgus.github.io/fmdb/html/Classes/FMDatabaseQueue.html) is quite useful, too. If you choose to not copy all of the files from the `src` directory, though, you may want to update `FMDB.h` to only reference the files that you included in your project.
+
+ Note, if you're copying all of the files from the `src` folder into to your project (which is recommended), you may want to drag the individual files into your project, not the folder, itself, because if you drag the folder, you won't be prompted to add the bridging header (see next point).
+
+2. If prompted to create a "bridging header", you should do so. If not prompted and if you don't already have a bridging header, add one.
+
+ For more information on bridging headers, see [Swift and Objective-C in the Same Project](https://developer.apple.com/library/ios/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html#//apple_ref/doc/uid/TP40014216-CH10-XID_76).
+
+3. In your bridging header, add a line that says:
+    ```objc
+    #import "FMDB.h"
+    ```
+
+4. Use the variations of `executeQuery` and `executeUpdate` with the `sql` and `values` parameters with `try` pattern, as shown below. These renditions of `executeQuery` and `executeUpdate` both `throw` errors in true Swift fashion.
+
+If you do the above, you can then write Swift code that uses `FMDatabase`. For example, as of Swift 3:
+
+```swift
+let fileURL = try! FileManager.default
+    .url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
+    .appendingPathComponent("test.sqlite")
+
+let database = FMDatabase(url: fileURL)
+
+guard database.open() else {
+    print("Unable to open database")
+    return
+}
+
+do {
+    try database.executeUpdate("create table test(x text, y text, z text)", values: nil)
+    try database.executeUpdate("insert into test (x, y, z) values (?, ?, ?)", values: ["a", "b", "c"])
+    try database.executeUpdate("insert into test (x, y, z) values (?, ?, ?)", values: ["e", "f", "g"])
+
+    let rs = try database.executeQuery("select x, y, z from test", values: nil)
+    while rs.next() {
+        if let x = rs.string(forColumn: "x"), let y = rs.string(forColumn: "y"), let z = rs.string(forColumn: "z") {
+            print("x = \(x); y = \(y); z = \(z)")
+        }
+    }
+} catch {
+    print("failed: \(error.localizedDescription)")
+}
+
+database.close()
+```

+## History
+
+The history and changes are availbe on its [GitHub page](https://github.com/ccgus/fmdb) and are summarized in the "CHANGES_AND_TODO_LIST.txt" file.
+
+## Contributors
+
+The contributors to FMDB are contained in the "Contributors.txt" file.
+
+## Additional projects using FMDB, which might be interesting to the discerning developer.
+
+ * FMDBMigrationManager, A SQLite schema migration management system for FMDB: https://github.com/layerhq/FMDBMigrationManager
+ * FCModel, An alternative to Core Data for people who like having direct SQL access: https://github.com/marcoarment/FCModel
+
+## Quick notes on FMDB's coding style
+
+Spaces, not tabs.  Square brackets, not dot notation.  Look at what FMDB already does with curly brackets and such, and stick to that style.
+
+## Reporting bugs
+
+Reduce your bug down to the smallest amount of code possible.  You want to make it super easy for the developers to see and reproduce your bug.  If it helps, pretend that the person who can fix your bug is active on shipping 3 major products, works on a handful of open source projects, has a newborn baby, and is generally very very busy.
+
+And we've even added a template function to main.m (FMDBReportABugFunction) in the FMDB distribution to help you out:
+
+* Open up fmdb project in Xcode.
+* Open up main.m and modify the FMDBReportABugFunction to reproduce your bug.
+    * Setup your table(s) in the code.
+    * Make your query or update(s).
+    * Add some assertions which demonstrate the bug.
+
+Then you can bring it up on the FMDB mailing list by showing your nice and compact FMDBReportABugFunction, or you can report the bug via the github FMDB bug reporter.
+
+**Optional:**
+
+Figure out where the bug is, fix it, and send a patch in or bring that up on the mailing list.  Make sure all the other tests run after your modifications.
+
+## Support
+
+The support channels for FMDB are the mailing list (see above), filing a bug here, or maybe on Stack Overflow.  So that is to say, support is provided by the community and on a voluntary basis.
+
+FMDB development is overseen by Gus Mueller of Flying Meat.  If FMDB been helpful to you, consider purchasing an app from FM or telling all your friends about it.
+
+## License
+
+The license for FMDB is contained in the "License.txt" file.
+
+If you happen to come across either Gus Mueller or Rob Ryan in a bar, you might consider purchasing a drink of their choosing if FMDB has been useful to you.
+
+(The drink is for them of course, shame on you for trying to keep it.)

This method also cannot be used in conjunction with `pragma` statements and the like. Second, note the lack of quotation marks in the SQL.

+/** To perform queries and updates on multiple threads, you'll want to use @c FMDatabaseQueue .
+
+ Using a single instance of @c FMDatabase from multiple threads at once is a bad idea.  It has always been OK to make a @c FMDatabase  object *per thread*.  Just don't share a single instance across threads, and definitely not across multiple threads at the same time.
+
+ Instead, use @c FMDatabaseQueue . Here's how to use it:
+
+ First, make your queue.
+
+@code
+FMDatabaseQueue *queue = [FMDatabaseQueue databaseQueueWithPath:aPath];
+@endcode
+
+ Then use it like so:
+
+@code
+[queue inDatabase:^(FMDatabase *db) {
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:1]];
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:2]];
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:3]];
+
+    FMResultSet *rs = [db executeQuery:@"select * from foo"];
+    while ([rs next]) {
+        //…
+    }
+}];
+@endcode
+
+ An easy way to wrap things up in a transaction can be done like this:
+
+@code
+[queue inTransaction:^(FMDatabase *db, BOOL *rollback) {
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:1]];
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:2]];
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:3]];
+
+    // if (whoopsSomethingWrongHappened) {
+    //     *rollback = YES;
+    //     return;
+    // }
+
+    // etc…
+    [db executeUpdate:@"INSERT INTO myTable VALUES (?)", [NSNumber numberWithInt:4]];
+}];
+@endcode
+
+ @c FMDatabaseQueue will run the blocks on a serialized queue (hence the name of the class).  So if you call @c FMDatabaseQueue 's methods from multiple threads at the same time, they will be executed in the order they are received.  This way queries and updates won't step on each other's toes, and every one is happy.
+
+ @warning Do not instantiate a single @c FMDatabase  object and use it across multiple threads. Use @c FMDatabaseQueue  instead.
+ 
+ @warning The calls to @c FMDatabaseQueue 's methods are blocking.  So even though you are passing along blocks, they will **not** be run on another thread.
