Adds a view to the end of the receiver’s list of subviews.
- iOS 2.0+
- tvOS 9.0+
The view to be added. After being added, this view appears on top of any other subviews.
This method establishes a strong reference to
view and sets its next responder to the receiver, which is its new superview.
Views can have only one superview. If
view already has a superview and that view is not the receiver, this method removes the previous superview before making the receiver its new superview.
