Allow all orientations for only one view controller

Question

I know this question was already asked in here, here and here. I tried all possible ways but wasn't successful.

I'm trying to develop an application in Swift (iOS 8), in which only one view controller can be viewed in all orientations others in only portrait.

For this, I have enabled only Portrait mode in Target->General->Device Orientation (because I want the application to operate only in portrait mode except one view controller).

I have added below code to the view controller that I want to operate in all orientations:

override func supportedInterfaceOrientations() -> Int {
    return Int(UIInterfaceOrientationMask.All.rawValue)
}

override func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation {
    return UIInterfaceOrientation.LandscapeLeft;
}

override func shouldAutorotate() -> Bool {
    return true;
}

But couldn't rotate it in landscape mode.

Answer 1

Do the following:

1. enable the desired orientations in the General Info Screen

2. in each ViewController, override the autorotation function with either true or false
   (true for the one that should rotate, false for the others):

   override var shouldAutorotate: Bool {
       return true
   }
   

Hope that helps :)
