动画结束回调CALayer？ [英] Animation End Callback for CALayer?

问题描述

使用iPhone CALayer，我想要一个旋转动画我的精神层，但我还想要一个回调的动画结束，热，这样做？

我想也许我应该使用CABasicAnimation，但我不知道如何使用CABasicAnimation旋转，任何想法？

感谢

解决方案

如果为CAAnimation设置了委托，可以添加回调方法：

   - （void）animationDidStop：（CAAnimation *）theAnimation finished：（BOOL）flag 
  pre> 
 
 
动画完成时调用。通过CGAffineTransform转换矩阵查找旋转动画的示例，如以下链接所示：

Using iPhone CALayer, I want a rotation animation for my spirit layer, but I also want a callback for the animation end, hot to do that? 

I think maybe I should use CABasicAnimation, but I don't know how to do rotation using CABasicAnimation, any idea?

Thanks
解决方案
If you set a delegate for a CAAnimation, you can add the callback method:
- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag
That gets called when the animation is complete.   Look for examples of rotating animations via a CGAffineTransform transformation matrix, as per this link:
