横向时 BAD_ACCESS

Question

I want to keep my view landscape. For that i am using this code but BAD_ACCESS is coming. Here I am writing this code for camera overlayView.

 -(void)viewDidLoad
 {
     [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeLeft];
     //Set Notifications so that when user rotates phone, the orientation is reset to landscape.
     [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
     //Refer to the method didRotate:   
     [[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(didRotate:)
              name:@"UIDeviceOrientationDidChangeNotification" object:nil];
     [super viewDidLoad];
 }

 - (void) didRotate:(NSNotification *)notification
 {
        //Maintain the camera in Landscape orientation
        [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeLeft];
 } 

Why it is giving BAD ACCESS?

Answer 1

To keep your view landscape, just return NO in your shouldAutorotateToInterfaceOrientation: method for portrait orientations, like tihs:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
