@implementation CJProperRotationNavigationController

- (BOOL)shouldAutorotate {
    if (self.topViewController != nil)
        return [self.topViewController shouldAutorotate];
    else
        return [super shouldAutorotate];
}

- (NSUInteger)supportedInterfaceOrientations {
    if (self.topViewController != nil)
        return [self.topViewController supportedInterfaceOrientations];
    else
        return [super supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    if (self.topViewController != nil)
        return [self.topViewController preferredInterfaceOrientationForPresentation];
    else
        return [super preferredInterfaceOrientationForPresentation];
}

@end

How can we make NavController to re-evaluate its orientation when it loads another view controller?

Any Idea how to make this work if i have a UITabBarController?
