First of all, this isn\'t a duplicate. I\'ve looked at all of the questions related to this on SO and none of them work for me. Hopefully it\'s just because I\'m new to iOS

    For those of you using Swift 2, you can follow Andre's answer, but in step one, use the code below in your AppDelegate.swift:

    class AppDelegate: UIResponder, UIApplicationDelegate {
    
    
    var blockRotation: Bool = false
    
    func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
    
        if (self.blockRotation) {
            print("supportedInterfaceOrientations - PORTRAIT")
            return UIInterfaceOrientationMask.Portrait
        } else {
            print("supportedInterfaceOrientations - ALL")
            return UIInterfaceOrientationMask.All
        }
    }
    

    supportedInterfaceOrientationsForWindow: now returns a UIInterfaceOrientationMask instead of an Int.

    Thanks to @ozgur for the fix which worked for me. I would 'vote up', but apparently I'm not good enough (whatever!) to vote whether a fix works or not. Anyway, here it is in Swift:

    In AppDelegate.swift:

    class AppDelegate: UIResponder, UIApplicationDelegate {
    
    
    var blockRotation: Bool = false
    
    func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> Int {
    
        if (self.blockRotation) {
            println("supportedInterfaceOrientations - PORTRAIT")
            return Int(UIInterfaceOrientationMask.Portrait.rawValue)
        } else {
            println("supportedInterfaceOrientations - ALL")
            return Int(UIInterfaceOrientationMask.All.rawValue)
        }
    }
    

    In the ViewController that you want to block rotation, add UIApplicationDelegate to your class...

    class LoginViewController: UIViewController, UITextFieldDelegate, UIApplicationDelegate {
    

    and then create a reference to the AppDelegate...

    var appDelegate = UIApplication.sharedApplication().delegate as AppDelegate
    

    In viewDidLoad, set appDelegate.blockRotation = true:

    override func viewDidLoad() {
        super.viewDidLoad()
    
        // Do any additional setup after loading the view.
    
        appDelegate.blockRotation = true
    
    }
    

    In viewWillAppear, set the orientation to force the device to the chosen orientation (Portrait in this example):

    override func viewWillAppear(animated: Bool) {
    
        let value = UIInterfaceOrientation.Portrait.rawValue
        UIDevice.currentDevice().setValue(value, forKey: "orientation")
    
    }
    

    Then in viewWillDisappear, or in prepareForSegue, set appDelegate.blockRotation = false:

    override func viewWillDisappear(animated: Bool) {
        appDelegate.blockRotation = false
    }
    

    This worked for me in this exact (multiple view controllers in a Navigation Controller) scenario, after many hours of reading other solutions on this site. Thanks again to @ozgur - I'd up-vote your answer if I could!

    Happy trails!

    Add your AppDelegate.h

    @property (nonatomic , assign) bool blockRotation;
    

    AppDelegate.m

    -(NSUInteger)application:(UIApplication *)application       supportedInterfaceOrientationsForWindow:(UIWindow *)window
    {
    if (self.blockRotation) {
        return UIInterfaceOrientationMaskPortrait;
    }
    return UIInterfaceOrientationMaskAll;
    }
    

    In view Controller that you want to disable rotation

    - (void)viewDidLoad
    {
     [super viewDidLoad];
        AppDelegate* shared=[UIApplication sharedApplication].delegate;
        shared.blockRotation=YES;
    }
    
    -(void)viewWillDisappear:(BOOL)animated{
      AppDelegate* shared=[UIApplication sharedApplication].delegate;
      shared.blockRotation=NO;
    
      }
    

    Swift 4.2 and later:

    In your AppDelegate.swift:

    var blockRotation = false
    
    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        if blockRotation {
            return .portrait
        }
        return .all
    }
    

    In your viewController:

    override func viewDidLoad() {
        super.viewDidLoad()
        AppDelegate.shared.blockRotation = true
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        AppDelegate.shared.blockRotation = false
    }

    My case has 3 view controller:
    - first view controller: portrait
    - second view controller: landscape right (has navigation controller and was presented by first view controller)
    - third view controller: portrait (has navigation controller and was pushed by second view controller )
    And this is my solution in swift 3:
    ------------------------------------
    At AppDelegate:
    - Add this property to save your setting

    private var orientation: UIInterfaceOrientationMask = .portrait
    

    -Then create a function to set rotate for your device:

    func rotateScreen(orientation: UIInterfaceOrientationMask) {
        self.orientation = orientation
        var value = 0;
        if orientation == .landscapeRight {
            value = UIInterfaceOrientation.landscapeRight.rawValue
        }else {
            value = UIInterfaceOrientation.portrait.rawValue
        }
        UIDevice.current.setValue(value, forKey: "orientation")
    }
    

    - Finally, implement support orientation method:

    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        return self.orientation
    }
    

    --------------------------------
    Then you can call like this before display destination view controller

    (UIApplication.shared.delegate as! AppDelegate).rotateScreen(orientation: .landscapeRight)
    

    For example, in my case: When user tap on button at the First to present the Second, I'll do like this

    (UIApplication.shared.delegate as! AppDelegate).rotateScreen(orientation: .landscapeRight)
    self.present(navigation, animated: true, completion: nil)
    

    And the close button at the Second I'll do like this

    (UIApplication.shared.delegate as! AppDelegate).rotateScreen(orientation: .portrait)
    self.dismiss(animated: true, completion: nil)
    

    That's all! You could never mind using navigation controller or not. Hope this helps you guys ^__^!

    UINavigationController+Rotation Category

    When u usign navigation controller SupportedInterfaceOrientaions of ViewController will not work adding this category to ur Project will get the response from your viewController also instead of NavigationController alone.

    In my case I have the view controller embedded in a navigation controller, and most of the solutions don't work because the viewcontroller depends on the navigation controller orientation. For this when you create the instance of the view controller you have to cast it to UINavigationController :

        let theViewController = UIViewController()
        if let navController = theViewController as? UINavigationController {
            navController.delegate = self
        }
    

    And then add this extension: extension PlaySplashViewController: UINavigationControllerDelegate {

    func navigationControllerSupportedInterfaceOrientations(_ navigationController: UINavigationController) -> UIInterfaceOrientationMask {
        return UIInterfaceOrientationMask.portrait
    }
    

    }

    In this case this going to set portrait orientation for the navigation controller so the view controller going to use this orientation too.
