Replaying a Core Animation animation?

Question

I was wondering, what if I want to replay an animation I have already added to the layer? Do I need to add the animation to the layer each and every time I want it to play, or there's a way to replay an animation I have already added?

Thanks, iLyrical.

Answer 1

Once animation gets finished then to repeat animation u will have to add new animation like this:

[yourView.layer removeAllAnimations];
[yourView.layer addAnimation:yourAnimation forKey:@"Key here"];

您可以使用repeatCount属性将动画配置为在完成动画之前重复一定次数，但是如果要重复已经完成的动画，则必须再次将其添加到图层。
