CAGradientLayer不会改变 [英] CAGradientLayer bounds not changing

问题描述

我将 CAGradientLayer 添加到 UIVIew ，当我向设备旋转视图时添加到大小增加（使用自动布局）但是CA层不会更改其大小。

I have a CAGradientLayer which is added to a UIVIew, when I rotate the device the view that it is added to increases in size (with autolayout) however the CA layer doesn't change its size.

我已尝试实现 viewDidLayoutSubviews 方法并在那里设置图层框架，但它没有任何区别。

I have tried implementing the viewDidLayoutSubviews method and setting the layers frame in there but it doesn't make any difference.

如果我离开视图然后导航设备回到它然后正确绘制图层。

Once the device is rotated if I navigate away from the view and then back to it then the layer gets drawn correctly.

推荐答案

你可以覆盖 - （void）layoutSubviews 在你的UIView子类中，然后更新图层框架。

You could override - (void)layoutSubviews in your UIView subclass and then update the layers frame.
