强制方向在 iOS 10 台设备中不起作用

Question

目前，当 AVPlayer 全屏按钮 pressed.I 尝试了类似的东西时，我正在强制改变方向

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")
        }
    }

}

以上代码在 iOS 11 中工作正常，但相同的代码在 iOS 10 及以下版本中不起作用

我们终于通过以下方式修复了它...

我们在 AppDelegate 上采用了一个 Bool 变量来检测方向变化。

var isLandScapeManualCheck = Bool()

接下来我们实现了以下应用delegate

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

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

            return UIInterfaceOrientationMask.landscapeRight
        }
//        return UIInterfaceOrientationMask.portrait

    }

基于 bool 值，我们有 return out orientation 模式。

iOS 10及以下版本应该这样..

在您的播放器控制器视图中..（指您的家庭控制器）

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
                    }

                }
            }
        }
    }

iOS11

之后

你应该打电话进来 viewDidLayoutSubviews

    UIViewController.attemptRotationToDeviceOrientation()

所以最后你的子 class 代码如下

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")
        }

    }

}
