将 UIButton 带到顶层

问题描述

我知道有一种方法可以将子视图带到层次结构的前面.但是，有没有一种方法可以将我放置在故事中的按钮调用并调用一个函数，该函数将使该按钮成为顶层，因此它不会被故事板中未添加的任何其他元素隐藏.

I know there is a way of bringing a subview to the front of the hierarchy. However is there a way of bringing a button that i have placed on a story and calling a function that will make that button the top layer so its not hidden by any other elements that are added that aren't in the story board.

谢谢，

推荐答案

这个问题我迟到了，但用 Swift 3 来回答还不算太晚

I am late for this question, but not too late to answer it by Swift 3

 view.bringSubview(toFront: theButton)
