Remarks
AddSubview(UIView) appends the view to the end of this UIView's Subviews. The methods InsertSubview(UIView, nint), InsertSubviewBelow(UIView, UIView), and InsertSubviewAbove(UIView, UIView) can be used to control the order.
To remove a UIView from Subviews, call RemoveFromSuperview() on the child UIView.
Since UIViews can only have direct ancestor, this will overwrite the existing Superview of the view.
A number of methods are called when a subview is added or removed:
- WillMoveToSuperview(UIView) :
- WillMoveToWindow(UIWindow) :
- WillRemoveSubview(UIView) :
- SubviewAdded(UIView) :
- MovedToSuperview() :
- MovedToWindow() :
The following diagram shows the sequence of calls resulting from a call to AddSubview(UIView). Note that the calls to WillMoveToWindow(UIWindow) and MovedToWindow() occur shortly after AddSubview(UIView) has completed.
