supportedInterfaceOrientations method not working on iOS 6 UIViewController

The method shouldAutorotateToInterfaceOrientation: is NOT supported in iOS 6. Its deprecated.

Apple provides a new method to get this thing done, in a much cleaner. You use supportedInterfaceOrientations instead. It returns all of the interface orientations that the view controller supports, a mask of interface orientation values.

In iOS 5, I used the method to change my orientation:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

return (UIInterfaceOrientationIsPortrait(interfaceOrientation));

}

In iOS 6 , I’m using:

-(NSUInteger)supportedInterfaceOrientations

{

return UIInterfaceOrientationMaskPortrait;

}

Also, in your delegate, I replaced this: [window addSubview:viewController.view];

With this: [window setRootViewController:viewController];
