UIView.AddSubview appends the view to the end of this UIKit.UIView's UIView.Subviews. The methods UIView.InsertSubview, UIView.InsertSubviewBelow, and UIView.InsertSubviewAbove can be used to control the order.

To remove a UIKit.UIView from UIView.Subviews, call UIView.RemoveFromSuperview on the child UIKit.UIView.

Since UIKit.UIViews can only have direct ancestor, this will overwrite the existing UIView.Superview of the view.

A number of methods are called when a subview is added or removed:

• UIView.WillMoveToSuperview
• UIView.WillMoveToWindow
• UIView.WillRemoveSubview
• UIView.SubviewAdded
• UIView.MovedToSuperview
• UIView.MovedToWindow

The following diagram shows the sequence of calls resulting from a call to UIView.AddSubview. Note that the calls to UIView.WillMoveToWindow and UIView.MovedToWindow occur shortly after UIView.AddSubview has completed.
