Difference between addSubview and insertSubview in UIView class

Question

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

Solution 1

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:).

Solution 2

Using insertSubView: you can specify the index, which determines z-order of views. A view with a higher index lies above those with lower indices.

Solution 3

I don't think there is a difference. addSubview: is simple a convenient method for

[view insertSubview:aView atIndex:[view.subviews count]]
