iOS 7: How to allow only portrait orientation for VC [duplicate]

Answer 1

If you want different orientation for view controllers, In AppDelegate add this method -

- (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;
}

and in your ViewController -

-(BOOL)shouldAutorotate{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations{
    return (UIInterfaceOrientationMaskAll);//Change this according to your need
}

Hope this will help.
