Question

好的所以我有一个视图控制器，它是一个AVPlayer。我希望该控制器能够自由旋转到横向模式和肖像

import Foundation
import UIKit
import AVFoundation
import AVKit

class EventPromoVideoPlayer: UIViewController {
    public var eventKey = ""

    override var prefersStatusBarHidden: Bool {
        return true
    }
    //URL of promo video that is about to be played
    private var videoURL: URL
    // Allows you to play the actual mp4 or video
    var player: AVPlayer?
    // Allows you to display the video content of a AVPlayer
    var playerController : AVPlayerViewController?

    init(videoURL: URL) {
        self.videoURL = videoURL
        super.init(nibName: nil, bundle: nil)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.backgroundColor = UIColor.gray
        let downSwipe = UISwipeGestureRecognizer(target: self, action: #selector(swipeAction(_:)))
        downSwipe.direction = .down
        view.addGestureRecognizer(downSwipe)


        //Setting the video url of the AVPlayer
        player = AVPlayer(url: videoURL)
        playerController = AVPlayerViewController()

        guard player != nil && playerController != nil else {
            return
        }
        playerController!.showsPlaybackControls = false
        // Setting AVPlayer to the player property of AVPlayerViewController
        playerController!.player = player!
        self.addChildViewController(playerController!)
        self.view.addSubview(playerController!.view)
        playerController!.view.frame = view.frame
        // Added an observer for when the video stops playing so it can be on a continuous loop
        NotificationCenter.default.addObserver(self, selector: #selector(playerItemDidReachEnd), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: self.player!.currentItem)
        //TODO: Need to fix frame of x and y
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        player?.play()
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        navigationController?.navigationBar.isHidden = true
        tabBarController?.tabBar.isHidden = true
    }

    override var supportedInterfaceOrientations:UIInterfaceOrientationMask {
        return UIInterfaceOrientationMask.all
    }
    // Allows the video to keep playing on a loop
    @objc fileprivate func playerItemDidReachEnd(_ notification: Notification) {
        if self.player != nil {
            self.player!.seek(to: kCMTimeZero)
            self.player!.play()
        }
    }

    @objc func cancel() {
        dismiss(animated: true, completion: nil)
    }

    @objc func swipeAction(_ swipe: UIGestureRecognizer){
        if let swipeGesture = swipe as? UISwipeGestureRecognizer {
            switch swipeGesture.direction {
            case UISwipeGestureRecognizerDirection.right:
                print("Swiped right")
                break
            case UISwipeGestureRecognizerDirection.down:
                print("Swiped Down")
                dismiss(animated: true, completion: nil)
                break
            case UISwipeGestureRecognizerDirection.left:
                print("Swiped left")
                break
            case UISwipeGestureRecognizerDirection.up:
                print("Swiped up")
                break
            default:
                break
            }
        }
    }
}

当我关闭屏幕时，我仍然需要先前的控制器处于纵向状态。这不应该是一个问题，因为纵向模式被锁定为我设置中的唯一方向，我想保持这种方式。但是我希望这个屏幕能够自由移动。任何想法和提示将不胜感激。

app delegate方法对我不起作用。在函数

中覆盖shouldAutoRotate或supportedInterfaceOrientations也没有

您可以在app delegate中使用以下方法。

在视图控制器中添加以下方法，将其显示为横向。

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    if let rootViewController = UIApplication.topViewController() {
        if (rootViewController.responds(to: Selector(("canRotate")))) || String(describing: type(of: rootViewController)) == "AVFullScreenViewController" {
            // Unlock landscape view orientations for this view controller
            return .allButUpsideDown;
        }
    }
    // Only allow portrait (standard behaviour)
    return .portrait
}

允许一个控制器能够旋转到横向模式
