How to bring subView to top from superview of its superview

Question

I have a view hierarchy as view 1 --> view 2 --> view 3. So, view 3 is subview of view 2 which is a subview of view 1. Now, from view 1, I want to bring view 3 to front without bringing view 2 to front. I cannot add view 3 in window due to relative positioning within view 2.

Any idea?

Answer 1

不，你不能。不应该从视图2中删除view3并添加到视图1，然后使用bringSubviewToFront:方法将其放到前面。

Answer 2

请参阅将视图移动到新的超级视图而不闪烁 ，您可以将相对帧转换为窗口，然后将视图添加到窗口，这将使视图3保持在其原始帧上

Answer 3

你可以尝试这个代码..

[self.view bringSubviewToFront:yourview];

Answer 4

You can not access view3 directly without accessing view2.

Try this :

[view2 bringSubviewToFront:view3];
[view1 bringSubviewToFront:view2];
