TYPagerController v2.0

TYPagerController 简单，强大，高度定制，页面控制器,水平滚动内容和标题栏,包含多种barStyle。
TYPagerController v2.0 重构优化代码，分离出TYPagerViewLayout布局类,添加更多功能，更加强大。
如果还想使用以前的版本可以查看分支v1.0.6 和 pod 'TYPagerController', '~> 1.0.6'

• TYPagerViewLayout 水平滚动页面的layout类，只需要initWithScrollView:即可实现水平滚动页面.
• TYPagerView 包含TYPagerViewLayout的水平滚动页面View
• TYPagerController 包含TYPagerViewLayout的水平滚动页面Controller。
• TYTabPagerBar Pager的标题 tabBar
• TYTabPagerView 包含TabBar的TYPagerView
• TYTabPagerController 包含TabBar的TYPagerController

注意：获取数据后必须调用reloadData.

Class

• TYPagerViewLayout ```objc @interface TYPagerViewLayout<__covariant ItemType> : NSObject

@property (nonatomic, weak, nullable) id dataSource; @property (nonatomic, weak, nullable) id delegate;

// strong,will control the delegate,don't set delegate on other place. @property (nonatomic, strong, readonly) UIScrollView *scrollView; // if viewcontroller's automaticallyAdjustsScrollViewInsets YES ,will cause frame problems, you can set YES, default YES @property (nonatomic, assign) BOOL adjustScrollViewInset;

@property (nonatomic, assign, readonly) NSInteger countOfPagerItems; @property (nonatomic, assign, readonly) NSInteger curIndex;// default -1

@property (nonatomic, strong, readonly) NSCache *memoryCache;; // will cache pagerView,you can set countLimit @property (nonatomic, assign) BOOL autoMemoryCache; // default YES

@property (nonatomic, assign) NSInteger prefetchItemCount;// preload left and right item's count , default 0

@property (nonatomic, strong, nullable, readonly) NSArray * visibleIndexs; @property (nonatomic, strong, nullable, readonly) NSArray * visibleItems;

// default YES, if NO,will not call delegate transitionFromIndex:toIndex:progress:,but will call transitionFromIndex:toIndex: @property (nonatomic, assign) BOOL progressAnimateEnabel;

// default NO, when scroll visible range change will add item.If YES add item only when scroll animate end, suggest set prefetchItemCount 1 or more @property (nonatomic, assign) BOOL addVisibleItemOnlyWhenScrollAnimatedEnd;

// default 0.5,when scroll progress percent will change index, only progressAnimateEnabel is NO or don't implement delegate transitionFromIndex: toIndex: progress: @property (nonatomic, assign) CGFloat changeIndexWhenScrollProgress;

  ##Usage Demo
  * TYTabPagerView
  ```objc
  - (void)addTabPagerView {
  TYTabPagerView *pagerView = [[TYTabPagerView alloc]init];
  pagerView.tabBar.layout.barStyle = TYPagerBarStyleCoverView;
  pagerView.tabBar.progressView.backgroundColor = [UIColor lightGrayColor];
  pagerView.dataSource = self;
  pagerView.delegate = self;
  [self.view addSubview:pagerView];
  _pagerView = pagerView;
  }
  
  #pragma mark - TYTabPagerViewDataSource
  
  - (NSInteger)numberOfViewsInTabPagerView {
  return _datas.count;
  }
  
  - (UIView *)tabPagerView:(TYTabPagerView *)tabPagerView viewForIndex:(NSInteger)index prefetching:(BOOL)prefetching {
  UIView *view = [[UIView alloc]initWithFrame:[tabPagerView.layout frameForItemAtIndex:index]];
  view.backgroundColor = [UIColor colorWithRed:arc4random()%255/255.0 green:arc4random()%255/255.0 blue:arc4random()%255/255.0 alpha:arc4random()%255/255.0];
  //NSLog(@"viewForIndex:%ld prefetching:%d",index,prefetching);
  return view;
  }
  
  - (NSString *)tabPagerView:(TYTabPagerView *)tabPagerView titleForIndex:(NSInteger)index {
  NSString *title = _datas[index];
  return title;
  }
  

• TYTabPagerController ```objc @interface TabPagerControllerDemoController : TYTabPagerController

• (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. self.title = @"TabPagerControllerDemoController"; self.tabBar.layout.barStyle = TYPagerBarStyleProgressView; self.dataSource = self; self.delegate = self;

  [self loadData]; }

• (void)loadData { _datas = [datas copy]; // must call reloadData [self reloadData]; }

#pragma mark - TYTabPagerControllerDataSource

• (NSInteger)numberOfControllersInTabPagerController { return _datas.count; }

• (UIViewController *)tabPagerController:(TYTabPagerController *)tabPagerController controllerForIndex:(NSInteger)index prefetching:(BOOL)prefetching { if (index%3 == 0) {

  CustomViewController *VC = [[CustomViewController alloc]init];
  VC.text = [@(index) stringValue];
  return VC;
  

  }else if (index%3 == 1) {

  ListViewController *VC = [[ListViewController alloc]init];
  VC.text = [@(index) stringValue];
  return VC;
  

  }else {

  CollectionViewController *VC = [[CollectionViewController alloc]init];
  VC.text = [@(index) stringValue];
  return VC;
  

  } }

• (NSString *)tabPagerController:(TYTabPagerController *)tabPagerController titleForIndex:(NSInteger)index { NSString *title = _datas[index]; return title; } ```
