The best way for iOS6 specifically is noted in "iOS6 By Tutorials" by the Ray Wenderlich team - http://www.raywenderlich.com/ and is better than subclassing UINavigationController for most cases.

I'm using iOS6 with a storyboard that includes a UINavigationController set as the initial view controller.

//AppDelegate.m - this method is not available pre-iOS6 unfortunately

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
NSUInteger orientations = UIInterfaceOrientationMaskAllButUpsideDown;

if(self.window.rootViewController){
    UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
    orientations = [presentedViewController supportedInterfaceOrientations];
}

return orientations;
}

//MyViewController.m - return whatever orientations you want to support for each UIViewController

- (NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskPortrait;
}
