力方向iOS中不工作10設備

目前我在做力方向變化時AVPlayer全屏按鈕pressed.I試過類似力方向iOS中不工作10設備

final class NewMoviePlayerViewController: AVPlayerViewController { 
    override func viewDidLayoutSubviews() { 
     super.viewDidLayoutSubviews() 
     if contentOverlayView?.bounds == UIScreen.main.bounds{ 
      DispatchQueue.main.async { 
       let value = UIInterfaceOrientation.landscapeRight.rawValue 
       UIDevice.current.setValue(value, forKey: "orientation") 
      } 
      print("full screen") 
     }else{ 
      DispatchQueue.main.async { 
      let value = UIInterfaceOrientation.portrait.rawValue 
      UIDevice.current.setValue(value, forKey: "orientation") 
      } 
      print("half screen") 
     } 
    } 

}

上面的代碼在iOS的11個工作精細的東西，但相同的代碼不在iOS的10及以下

版本工作

'contentOverlayView .bounds == UIScreen.main.bounds'爲真在IOS 10（及以下）或問題是內部'UIDevice.current.setValue（值，forKey：「取向」）？' ？ –

@AlbertoCantallops裏面的條件，但強制方向代碼不工作 – karthikeyan

看看https://stackoverflow.com/questions/26357162/how-to-force-view-controller-orientation-in-ios-8有一堆不同的方法。注意接受的答案是你是如何做到的，但https://stackoverflow.com/a/28220616/7064692也許可以幫助 –

我們終於用下面的方式固定它...

我們已經採取了一個Bool變量上APPD elegate檢測方向變化。

var isLandScapeManualCheck = Bool()

接下來，我們已經實現以下應用委託

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

     if isLandScapeManualCheck == false{ 
     return UIInterfaceOrientationMask.portrait 
     }else{ 

      return UIInterfaceOrientationMask.landscapeRight 
     } 
//  return UIInterfaceOrientationMask.portrait 

    }

基於我們回到了方向模式布爾值。

iOS的10及以下版本應該遵循這樣..

在您的PlayerController視圖。（意思是你的家控制器）

if #available(iOS 11, *) { 

       }else{ 
        playerVwController.contentOverlayView!.addObserver(self, forKeyPath: "bounds", options: NSKeyValueObservingOptions.new, context: nil) 
       } 



override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { 
     if keyPath == "bounds"{ 
      let rect = change![.newKey] as! NSValue 

      if let playerRect: CGRect = rect.cgRectValue as CGRect { 
       if playerRect.size == UIScreen.main.bounds.size { 
        print("Player in full screen") 
        let value = UIInterfaceOrientation.landscapeLeft.rawValue 
        UIDevice.current.setValue(value, forKey: "orientation") 
        isLandScapeManualCheck = true 
       } else { 
        DispatchQueue.main.async { 
        let value = UIInterfaceOrientation.portrait.rawValue 
        UIDevice.current.setValue(value, forKey: "orientation") 
        print("Player not in full screen") 
        isLandScapeManualCheck = false 
        } 

       } 
      } 
     } 
    }

後的iOS 11

你應該viewDidLayoutSubviews調用

UIViewController.attemptRotationToDeviceOrientation()

因此，最後你的子類代碼像belo瓦特

final class NewMoviePlayerViewController: AVPlayerViewController { 
    override func viewDidLayoutSubviews() { 
     UIViewController.attemptRotationToDeviceOrientation() 
     super.viewDidLayoutSubviews() 
     if contentOverlayView?.bounds == UIScreen.main.bounds{ 
      DispatchQueue.main.async { 
       let value = UIInterfaceOrientation.landscapeRight.rawValue 
       UIDevice.current.setValue(value, forKey: "orientation") 
      } 
//   self.contentOverlayView?.transform = CGAffineTransform(rotationAngle: CGFloat(Double.pi/2)) 
      print("full screen") 
     }else{ 
      DispatchQueue.main.async { 
      let value = UIInterfaceOrientation.portrait.rawValue 
      UIDevice.current.setValue(value, forKey: "orientation") 
      } 
//   self.contentOverlayView?.transform = CGAffineTransform.identity 

      print("half screen") 
     } 

    } 

}
