UIView类中addSubview和insertSubview之间的区别 [英] Difference between addSubview and insertSubview in UIView class

问题描述

以编程方式添加视图时， addSubview 和 insertSubView 方法有什么区别？

What is the difference between addSubview and insertSubView methods when a view is added programmatically?

推荐答案

唯一的区别在于添加视图的位置：它是否是最前面的视图（ addSubview：），或者它在第5个子视图之前，（ insertSubview：atIndex：）或者它是否紧跟在另一个子视图之后（ insertSubview：aboveSubview ：）。

The only difference is in where the view is added: whether it is the frontmost view (addSubview:), or it is before the 5th subview, (insertSubview:atIndex:) or if it is immediately behind another subview (insertSubview:aboveSubview:).
