objective c - disable autorotate on a single UIViewController in iOS6

Question

I have a project using UINavigationController and segues working properly good, all of them rotate correctly, the thing is... I just want to disable autorotation on a specific UIViewController. I tried this:

- (BOOL)shouldAutorotateToInterfaceOrientation:
                               (UIInterfaceOrientation)interfaceOrientation {    
    return NO;
}

// New Autorotation support for iOS 6.
- (BOOL)shouldAutorotate NS_AVAILABLE_IOS(6_0){
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

but it's not working, my UIViewController keeps rotating automatically, any help will be welcome :)

Per the View Controller Programing Guide

If you want to temporarily disable automatic rotation, avoid manipulating the orientation masks to do this. Instead, override the shouldAutorotate method on the initial view controller. This method is called before performing any autorotation. If it returns NO, then the rotation is suppressed.

So you need to subclass 'UINavigationController', implement shouldAutorotate and use your navigation controller class in your storyboard.

- (BOOL)shouldAutorotate
{
    id currentViewController = self.topViewController;

    if ([currentViewController isKindOfClass:[DetailViewController class]])
        return NO;

    return YES;
}
