iOS6: supportedInterfaceOrientations not working (is invoked but the interface still rotates)

Question

In my app I have multiple views, some views need to support both portrait and landscape, while other views need to support portrait only. Thus, in the project summary, I ha

As stated by others if you're using a UINavigationController and you want to customize various views you'll want to subclass the UINavigationController and make sure you have these two components:

@implementation CustomNavigationController

// -------------------------------------------------------------------------------
//  supportedInterfaceOrientations:
//  Overridden to return the supportedInterfaceOrientations of the view controller
//  at the top of the navigation stack.
//  By default, UIViewController (and thus, UINavigationController) always returns
//  UIInterfaceOrientationMaskAllButUpsideDown when the app is run on an iPhone.
// -------------------------------------------------------------------------------
- (NSUInteger)supportedInterfaceOrientations
{
    return [self.topViewController supportedInterfaceOrientations]; 
}

// -------------------------------------------------------------------------------
//  shouldAutorotate
//  Overridden to return the shouldAutorotate value of the view controller
//  at the top of the navigation stack.
//  By default, UIViewController (and thus, UINavigationController) always returns
//  YES when the app is run on an iPhone.
// -------------------------------------------------------------------------------
- (BOOL)shouldAutorotate
{
    return [self.topViewController shouldAutorotate];
}

Then in any view that is a portrait only you would include:

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

And in any view that is everything but upside down:

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}
