iphone - 如何获取CATransition/Animation的结束事件？

Question

我的代码如下:

CATransition *transition = [CATransition animation];
transition.duration = duration 

我希望得到CATransition/Animation的结束事件。可能吗？

Answer 1

CAAnimation(CATransition 是其子类)具有您可以使用的委托(delegate)方法 animationDidStop:finished:。

设置委托(delegate)属性并实现方法:

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...
}
