将UIView的子视图放在其CALayer前面？ [英] put subviews of a UIView in front of its CALayer?

问题描述

这可能吗？基本上，我想给UIView一个子视图，并使该子视图在视图层的前面（更具体地说，在该层的边界的前面）。

Is this possible? Basically, I want to give my UIView a subview, and have that subview be in front of the view's layer (more specifically, in front of said layer's border).

Of当然，我可以通过在视图的超级视图中创建两个子视图，一个在另一个子视图之上，来达到我想要的效果。但是，我宁愿避免这种情况。

Of course I could achieve the effect I want by making two subviews of the view's superview, one on top of the other. But I'd rather avoid that if possible.

推荐答案

我自己寻找了一段时间。我不认为有可能。正如您所暗示的，我通过将子视图和父视图添加到同一容器父视图来解决了该问题。然后，只需对两个子视图进行排序即可，以便您的子视图位于另一个视图及其边框之上。

I looked for this for a while myself; i don't believe it is possible. I solved the issue by, as you hint at, adding the subview and the parent to the same 'container' superview. Then its just a matter of ordering the two subviews, so that your subview is above the other and its border.
