# UIInterfaceOrientation

The initial orientation of the app’s user interface.

## Possible Values

UIInterfaceOrientationPortrait: The device is in portrait mode, with the device upright and the Home button on the bottom. UIInterfaceOrientationPortraitUpsideDown: The device is in portrait mode but is upside down, with the device upright and the Home button at the top. UIInterfaceOrientationLandscapeLeft: The device is in landscape mode, with the device upright and the Home button on the left. UIInterfaceOrientationLandscapeRight: The device is in landscape mode, with the device upright and the Home button on the right.

## Discussion

Discussion The default value is UIInterfaceOrientationPortrait. If you add the UISupportedInterfaceOrientations key to the information property list, the system ignores this key. For more information, see UIInterfaceOrientation.
