The UIInterfaceOrientation represents the rotation of the user interface and, in portrait modes, is the opposite of the Orientation property. For instance, if the device is rotated 90 degrees clockwise from normal portrait mode such that the home button is to the left, the InterfaceOrientation property will be LandscapeLeft but the Orientation property will be LandscapeRight.
