iOS 6 Tab Bar App: shouldAutorotate not working

Question

I momently developing a application with a tab bar and some navigation view controllers in Storyboard using iOS 6 and Xcode 4.5

Usually the app should support all interface orientations but I have two views that only should support portrait mode.

So I added the following code to the view controllers:

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationPortrait;
}

On a other app I developed without storyboard and navigation view controller on iOS 6 it works but her NOT! :/

I hope someone can help, because I found some other post that where not helpful...

With best regards from Germany

EDIT:

I also tried - Doesn't work! :

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;

}

Excellent answer by Jonathan.

I modified his code little bit to handle navigation controller in a single snippet.

- (BOOL)shouldAutorotate {
    if (self.selectedViewController) {
        if ([self.selectedViewController isKindOfClass:[UINavigationController class]]) {
            return [[[(UINavigationController*)self.selectedViewController viewControllers] lastObject] shouldAutorotate];
        }
        return [self.selectedViewController shouldAutorotate];
    } else {
        return YES;
    }
}

- (NSUInteger)supportedInterfaceOrientations {
    if (self.selectedViewController) {
        if ([self.selectedViewController isKindOfClass:[UINavigationController class]]) {
            return [[[(UINavigationController*)self.selectedViewController viewControllers] lastObject] supportedInterfaceOrientations];
        }
        return [self.selectedViewController supportedInterfaceOrientations];
    } else {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    }
}
