实例讲解iOS中的CATransition转场动画使用

#import <QuatzCore/CAAnimation.h> 
CATransition *myTransition=[CATransition animation];//创建CATransition 
myTransition.duration=0.3;//持续时长0.3秒 
myTransition.timingFunction=UIViewAnimationCurveEaseInOut;//计时函数，从头到尾的流畅度 
myTransition.type=kCATransionPush;//动画类型 
myTransition.subtype=kCATransitionFromLeft;//子类型 
//要令一个转场生效，组要将动画添加到将要变为动画视图所附着的图层。例如在两个视图控制器之间进行转场，那就将动画添加到窗口的图层中： 
[[self.view.superview layer]addAnimation:myTransition forKey:nil ]; 
//如果是将控制器内的子视图转场到另一个子视图，就将动画加入到视图控制器的图层。还有一种选择，用视图控制器内部的视图作为替代，将你的子视图作为主视图的子图层： 
 [ self.view.layer addAnimation:myTransition forKey:nil ]; 
[ self.view addSubView:newView ]; 
[oldView removeFromSuperview]; 
//如果你使用的是导航控制器，可以将动画加到导航控制器的视图图层中。 
[ navigationController.view.layer addAnimation:myTransition forKey:nil  ];
