Rotation only in one ViewController

Question

I am trying to rotate one view while all other views (5) are fixed to portrait. The reason is that in that one view I want the user to watch pictures which he saved before.

Answer 1

Just wanted to share my solution as someone who has spent too much time rotating one view controller in the app:

var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation { get }

overriding this UIViewController method helped me do what I need.

1. On the view controller that you want to rotate do this for landscape left rotation:

override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation { return UIInterfaceOrientation.landscapeLeft }

2. Make sure you enable rotation in the desired directions from the project settings:

3. And add this to AppDelegate to disable other screens' rotation:

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