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也没有答案 0 :(得分：0)
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
}
