Return Value

Discussion
Always specify at least one size characteristic when calling this method. Pass nil or leave out a characteristic to indicate that the frame should adopt this view’s sizing behavior, constrained by the other non-nil arguments.
Any non-nil minimum, ideal, or maximum parameters specified for each dimension must be in ascending order.
