 [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:)            name:UIDeviceOrientationDidChangeNotification object:nil]; 
    //Whenever the device orientation changes, orientationChanged will be called

및 orientationChanged의 몸을 아래로있는 viewDidLoad에서 코드를 작성하고하는 것은 : 방법 나는이 방법의 행동을 이해 할 수없는 오전

 - (void)orientationChanged:(NSNotification *)notification 
    { 
     UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation; 

     NSLog(@"Method is Called"); 

     self.view.frame = CGRectMake(0, 0, 480, 320); 
     //self.view.superview.frame = CGRectMake(-50, -70, 800, 900); 

     //Based upon which orientation the device is in, update your View rotations. 
     //A simple view.transform = CGAffineTransformMakeRotation(whatever); will work well. 
    }

을 따르고, 어떤 시체는 것을 말해 줄 수 이 두 라인이 어떤 작업을 수행하는지는 self.view.frame의 첫 번째 변화 프레임, 그리고 내가 주석 않았다 수퍼에 대한 두 번째.
