Setting device orientation in Swift iOS

Question

I am working on a swift app for iPhone. There is a modal view in my application that I want only to be in portrait view.

My question is, how do I programmatically force the phone to not allow rotation? In other words, I am looking for code that will not allow a modal view to be displayed in landscape mode (turning on portrait rotation lock).

This is just for 1 modal view, so I can't turn off rotation for the entire app, otherwise I would just disable rotation altogether.

I found code in my research here But it is in objective C, in case that helps. Thanks!

Hi for LandscapeLeft and LandscapeRight (Update Swift 2.0)

And you have this in info

And UIController

override func shouldAutorotate() -> Bool {     return true }  override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {     return [UIInterfaceOrientationMask.LandscapeLeft,UIInterfaceOrientationMask.LandscapeRight] } 

For PortraitUpsideDown and Portrait use that

override func shouldAutorotate() -> Bool {     if (UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeLeft ||         UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeRight ||         UIDevice.currentDevice().orientation == UIDeviceOrientation.Unknown) {             return false     }     else {         return true     } }  override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {     return [UIInterfaceOrientationMask.Portrait ,UIInterfaceOrientationMask.PortraitUpsideDown] }

Edit :

Other solution :

extension UINavigationController {     public override func shouldAutorotate() -> Bool {         if visibleViewController is MyViewController {             return true   // rotation         } else {             return false  // no rotation         }     }      public override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {         return (visibleViewController?.supportedInterfaceOrientations())!     } }

You can paste these methods in the ViewController of each view that needs to be portrait:

override func shouldAutorotate() -> Bool {     return false }  override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {     return UIInterfaceOrientationMask.Portrait }
