推荐答案

CAAnimation（CATransition是其子类）具有委托方法 animationDidStop：完成：您可以使用。

CAAnimation (which CATransition is a subclass of) has the delegate method animationDidStop:finished: which you can use.

设置委托属性并实现方法：

Set the delegate property and implement the method:

CATransition *transition = [CATransition animation];
transition.duration = duration;
transition.delegate = self;
//other settings...
//call addAnimation...

...

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag
{
    //do what you need to do when animation ends...
}
