iOS Allow different screen orientation withouth autorotation

Question

I want to keep a portrait orientation even if user rotate the phone. At the same time, I want to change the orientation with a button. If I put only portrait as supported orientation in plist and then rotate, application gives me error. If I put all the supported orientation but shouldAutorotate method to NO, Application crashes. So, basically as I can see I can only support multiple orientation if I let the application to autorotate.

Can I achieve what I need?

Answer 1

shouldAutorotate

this is a get-only property.

what you can do is:

override var shouldAutorotate: Bool {
    return false
}

Answer 2

May be the following line of code will work for you. set orientation programmatically.

1. In your Appdelegate class write this code:

   var orientationLock = UIInterfaceOrientationMask.all

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

2.Make custom helper class as follows:

struct AppUtility {

    static func lockOrientation(_ orientation: UIInterfaceOrientationMask) {

        if let delegate = UIApplication.shared.delegate as? AppDelegate {
            delegate.orientationLock = orientation
        }
    }

    /// OPTIONAL Added method to adjust lock and rotate to the desired orientation
    static func lockOrientation(_ orientation: UIInterfaceOrientationMask, andRotateTo rotateOrientation:UIInterfaceOrientation) {

        self.lockOrientation(orientation)

        UIDevice.current.setValue(rotateOrientation.rawValue, forKey: "orientation")
    }

}

3. then use it in your desire viewcontroller like:

   override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated)

    AppUtility.lockOrientation(.portrait) // Or to rotate and lock // AppUtility.lockOrientation(.portrait, andRotateTo: .portrait) 

   }

   override func viewWillDisappear(_ animated: Bool){ super.viewWillDisappear(animated)

    // Don't forget to reset when view is being removed AppUtility.lockOrientation(.all) 

   }

note: keep remember Require Full Screen option is checked from target settings.
