The Relationship of the Frame, Bounds, and Center Properties
A view object tracks its size and location using its frame, bounds, and center properties:
● The frame property contains the frame rectangle, which specifies the size and location of the view in its
superview’s coordinate system.
● The bounds property contains the bounds rectangle, which specifies the size of the view (and its content
origin) in the view’s own local coordinate system.
● The center property contains the known center point of the view in the superview’s coordinate system.
