我想创建一种动画，以一种时钟方式为CAShapeLayer的笔触着色，然后，一个动画以相同的方向消除笔触颜色。这样可以有效地放置和删除笔划。
到目前为止，它看起来很像想要的东西，只是在第二次调用CALayer之前，笔画闪烁为“满”，然后消失了，然后动画再次播放。 / p>
我同意我的代码到目前为止还不是最好的，但是我一直在寻找解释，但没有找到任何有用的答案。
有人可以向我解释那里发生了什么吗？以及如何避免呢？
这是我的游乐场文件
fullAnimate答案 0 :(得分：1)
在空的动画块中添加以下两行，您可以轻松找出原因。
func emptyAnimate(completion: @escaping ()->Void) {
self.state = .progress
circleProgressLayer.removeAllAnimations()
CATransaction.begin()
. .....
animation.fillMode = .forwards
animation.isRemovedOnCompletion = false
......
}
