将-removeAllAnimations发送到一个层也会传播到它的所有子层吗？ [英] Will sending -removeAllAnimations to a layer also propagate to all it's sublayers?

问题描述

我想知道如果我将-removeAllAnimations发送到父图层，子图层动画是否会继续播放。

I wonder if sublayer animations would continue to play if I send -removeAllAnimations to a parent layer.

推荐答案

按照 removeAllAnimations 的文档：

删除附加到 接收器 。

Remove all animations attached to the receiver.

您需要遍历子图层并从中删除动画：

You'll need to iterate through the sublayers and remove animations from them as well:

for (CALayer* layer in [containerLayer sublayers]) {
  [layer removeAllAnimations];
}
