将先前添加的视图置于最前面 [英] Bring previously added view to front

问题描述

我的问题如下:

我有一个视图，并向该视图中依次添加了3个subViews(view1，view2，view3).视图略有重叠.我想将第一个视图显示在顶部，但我无法使其正常工作.

I have a view and to that view I add 3 subViews(view1,view2,view3) in that order. The views slightly overlap. I want to bring the first view to the top but I just can't get it to work.

我尝试使用insertSubview:atIndex:添加视图并为view1提供更大的索引，然后尝试使用addSubview:然后再带SubSubviewToTop，但似乎没有任何作用.

I tried adding the views with insertSubview:atIndex: and giving view1 a larger index and I tried using addSubview: and then bringSubviewToTop but nothing seems to work.

有什么想法吗?

P.S.我不能以其他顺序添加视图.必须按此顺序添加它们.

P.S. I can't add the views in a different order. They have to be added in this order.

推荐答案

bringSubviewToFront应该可以工作，只需确保正确使用即可.用法是.

bringSubviewToFront should work, just make sure you're using it correctly. The usage is.

[parentView bringSubviewToFront:view1];
