是否可以在CAKeyFrameAnimation中向后播放路径？ [英] Is it possible to play a path backwards in a CAKeyFrameAnimation?

问题描述

我想基于CGPath设置CALayer的位置动画，但我想向后播放它。

I want to animate the position of a CALayer based on a CGPath, but I want to play it backwards.

有没有办法让路径向后动画，或者反转CGPath？

Is there any way to animate a path backwards, or reverse a CGPath?

推荐答案

animation.speed = -1;

？
