Disable rotation for View Controller in Navigation Controller

Question

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

Answer 1

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 ^__^!
