CALayers没有根据UIView的界限变化调整大小。为什么？ [英] CALayers didn't get resized on its UIView's bounds change. Why?

问题描述

我有一个 UIView ，它在其图层中添加了大约8个不同的 CALayer 子图层。
如果我修改了视图的边界（动画），那么视图本身会缩小（我用 backgroundColor 检查了它），但子图层的大小保持不变。

I have a UIView which has about 8 different CALayer sublayers added to its layer. If I modify the view's bounds (animated), then the view itself shrinks (I checked it with a backgroundColor), but the sublayers' size remains unchanged.

如何解决这个问题？

推荐答案

我使用的是Solin使用的相同方法，但该代码中存在拼写错误。该方法应该是：

I used the same approach that Solin used, but there's a typo in that code. The method should be:

- (void)layoutSubviews {
  // resize your layers based on the view's new bounds
  mylayer.frame = self.bounds;
}

出于我的目的，我一直希望子图层的大小完整父视图。将该方法放在视图类中。

For my purposes, I always wanted the sublayer to be the full size of the parent view. Put that method in your view class.
