  addObserver: self

      selector:@selector(orientationChanged)

     name:UIDeviceOrientationDidChangeNotificationobject:

     nil];


/*

*/

- (void) orientationChanged

{

     UIDeviceOrientation deviceOrientation = [[UIDevice currentDevice] orientation];//获取当前设备的方向

}

 

/*

 设备可能的方向

*/

typedefenum {

    UIDeviceOrientationUnknown,

    UIDeviceOrientationPortrait,            // Device oriented vertically, home button on the bottom

    UIDeviceOrientationPortraitUpsideDown// Device oriented vertically, home button on the top

    UIDeviceOrientationLandscapeLeft,       // Device oriented horizontally, home button on the right

    UIDeviceOrientationLandscapeRight,      // Device oriented horizontally, home button on the left

    UIDeviceOrientationFaceUp,              // Device oriented flat, face up

    UIDeviceOrientationFaceDown             // Device oriented flat, face down
