Discussion
See the boundsRotation method description for more information. This method neither redisplays the view nor marks it as needing display. You must do this yourself by calling the display() method or setting the needsDisplay property.
This method posts an boundsDidChangeNotification to the default notification center if the view is configured to do so.
