@在iOS7之前，View Controller的切换主要有4种：
1. Push/Pop，NavigationViewController
2. Present and dismis Modal
3. UITabBarController
4. addChildViewController(一般用于自定义的继承于 UIViewController 的容器子类)
iOS5,调用- (void)transitionFromViewController:(UIViewController *)fromViewController toViewController:(UIViewController *)toViewController duration:(NSTimeInterval)duration options:(UIViewAnimationOptions)options animations:(void (^)(void))animations completion:(void (^)(BOOL finished))completion NS_AVAILABLE_(5_0);
(1)前面3种方法这里就不多说了,很常见的方法.至于第四种,我在前面文章-剖析网易标签栏的效果中已经做了阐述,但是它提供的容器转场动画只可以实现一些简单的UIView动画，但是难以重用，耦合高.
(2)关键的API:
A.动画控制器 (Animation Controllers) 遵从 UIViewControllerAnimatedTransitioning 协议，并且负责实际执行动画。
B.交互控制器 (Interaction Controllers) 通过遵从 UIViewControllerInteractiveTransitioning 协议来控制可交互式的转场。
C.转场代理 (Transitioning Delegates) 根据不同的转场类型方便的提供需要的动画控制器和交互控制器。
其中UINavigationControllerDelegate delegate 中新增了2个方法给NavigationController
UIViewControllerTransitioningDelegate 新增transitioningDelegate 给Modal的Present和Dismis
UITabBarControllerDelegate delegate
- (id )tabBarController:(UITabBarController *)tabBarController
interactionControllerForAnimationController: (id )animationController NS_AVAILABLE_IOS(7_0);
- (id )tabBarController:(UITabBarController *)tabBarController
animationControllerForTransitionFromViewController:(UIViewController *)fromVC
toViewController:(UIViewController *)toVC NS_AVAILABLE_IOS(7_0);
D.转场上下文 (Transitioning Contexts) 定义了转场时需要的元数据，比如在转场过程中所参与的视图控制器和视图的相关属性。 转场上下文对象遵从 UIViewControllerContextTransitioning 协议，并且这是由系统负责生成和提供的。
E.转场协调器(Transition Coordinators) 可以在运行转场动画时，并行的运行其他动画。 转场协调器遵从 UIViewControllerTransitionCoordinator 协议。
(3)新的API主要提供了2种VC切换的方式:
A.非交互式切换，即定义一种从一个VC到另一个VC的动画效果，切换的时候自动播放，
B.交互式切换，这种方式同样需要定义动画效果，只是这个动画效果会根据跟随交互式手势来切换VC并同时播放动画效果。iOS7提供了一个默认的基于百分比的动画实现 UIPercentDrivenInteractiveTransition,而且根据WWDC的说明，最简单的实现交互式动画的方法就是通过继承 UIPercentDrivenInteractiveTransition。

在tabBarController模式下怎么对UIViewController刷新
在该控制类里面写一个方法：- (void)setDataSource{
tabview.dataSource =
tabview.dataSource =}在AppDelegate.m中调用：- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {
if(viewController.tabBarItem.tag == 3){
UINavigationController *navigationctr = (UINavigationController *)viewC
SecondViewController *secvc = (SecondViewController *)navigationctr.topViewC
[secvc setDataSource];
