Orientation does not change after pressing (push segue) a View of UINavigationViewController

Question

I put a UIViewControllerin UINavigationController. The view orientation of this controller is set to Portait. When I click a new view on this UIViewController, which is only a landscape, the portrait is also displayed on the new view, and not on its orientation landscape.

I tried to subclass UINavigationController and added the following methods:

- (BOOL)shouldAutorotate {
    return self.topViewController.shouldAutorotate;
}

- (NSUInteger)supportedInterfaceOrientations {
    return self.topViewController.supportedInterfaceOrientations;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return self.topViewController.preferredInterfaceOrientationForPresentation;
}

In rootViewController (LoginViewController) I did this:

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

- (BOOL)shouldAutorotate
{
    return YES;
}

In pushViewController (custom ViewController) I did this:

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

-(BOOL)shouldAutorotate {
    return YES;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft;
}

:

AppDelegate.m .

#pragma mark Orientation Code
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    NSUInteger orientations = UIInterfaceOrientationMaskAll;

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

viewController.m

#pragma mark Orientation
- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
