力方向iOS中不工作10设备

问题描述：

目前我在做力方向变化时AVPlayer全屏按钮pressed.I试过类似力方向iOS中不工作10设备

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") 
     } 
    } 

}

上面的代码在iOS的11个工作精细的东西，但相同的代码不在iOS的10及以下

版本工作

'contentOverlayView .bounds == UIScreen.main.bounds'为真在IOS 10（及以下）或问题是内部'UIDevice.current.setValue（值，forKey： “取向”）？' ？ –

@AlbertoCantallops里面的条件，但强制方向代码不工作 – karthikeyan

看看https://*.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://*.com/a/28220616/7064692也许可以帮助 –

我们终于用下面的方式固定它...

我们已经采取了一个Bool变量上APPD elegate检测方向变化。

var isLandScapeManualCheck = Bool()

接下来，我们已经实现以下应用委托

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

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

      return UIInterfaceOrientationMask.landscapeRight 
     } 
//  return UIInterfaceOrientationMask.portrait 

    }

基于我们回到了方向模式布尔值。

iOS的10及以下版本应该遵循这样..

在您的PlayerController视图。（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 
        } 

       } 
      } 
     } 
    }

后的iOS 11

你应该viewDidLayoutSubviews调用

UIViewController.attemptRotationToDeviceOrientation()

因此，最后你的子类代码像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") 
     } 

    } 

}
