iphone - Difference between addSubview and insertSubview in UIView class

Question

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

Answer 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:).
