avfoundation - iOS: AVPlayerViewController enable fullscreen rotation in portrait oriented application -

-

i have uiviewcontroller, contains avplayerviewcontroller avplayer. want enable rotation avplayerviewcontroller(when video on fullscreen) , disable rotation uiviewcontroller. how can enable rotation videos(on fullscreen) in app?

swift 2.2 in appdelegate allow rotation player:

func application(application: uiapplication, supportedinterfaceorientationsforwindow window: uiwindow?) -> uiinterfaceorientationmask {         guard let vc = (window?.rootviewcontroller?.presentedviewcontroller) else {             return .portrait         }          if (vc.iskindofclass(nsclassfromstring("avfullscreenviewcontroller")!)) {             return .allbutupsidedown         }          return .portrait     }

than create , use subclass of avplayerviewcontroller portrait mode when player exit full screen mode:

class yourvideoplayer: avplayerviewcontroller {      override func viewdidlayoutsubviews() {         super.viewdidlayoutsubviews()         if view.bounds == contentoverlayview?.bounds { uidevice.currentdevice().setvalue(uiinterfaceorientation.portrait.rawvalue, forkey: "orientation")         }     }
