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，稳定，已经在项目中使用
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.
