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.

##Usage Demo

• TYTabPagerView

  - (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

  @interface TabPagerControllerDemoController : TYTabPagerController
  
  - (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view.
  self.title = @"TabPagerControllerDemoController";

  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) {
