要获取deinit,您的对象必须是AVPlayerItem

为此,只需在deinit上使用deinit属性

现在,一旦视频结束,您将收到通知!

看我的例子:

let videoPlayer = AVPlayer(URL: url)       

NSNotificationCenter.defaultCenter().addObserver(self, selector: "playerDidFinishPlaying:",
        name: AVPlayerItemDidPlayToEndTimeNotification, object: videoPlayer.currentItem)

func playerDidFinishPlaying(note: NSNotification) {
    print("Video Finished")
}

斯威夫特3

let videoPlayer = AVPlayer(URL: url)       

NotificationCenter.default.addObserver(self, selector: Selector(("playerDidFinishPlaying:")), 
       name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: videoPlayer.currentItem)

func playerDidFinishPlaying(note: NSNotification) {
    print("Video Finished")
}

不要忘记删除deinit中的观察者

NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: .AVPlayerItemDidPlayToEndTime, object: nil)

Swift 3.0

let videoPlayer = AVPlayer(URL: url)

NotificationCenter.default.addObserver(self, selector:#selector(self.playerDidFinishPlaying(note:)),name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem)

@objc func playerDidFinishPlaying(note: NSNotification){
        print("Video Finished")
    }

Swift 4.2版本:

var player: AVPlayer!
  //
  //
// Configure Player
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    let filepath: String? = Bundle.main.path(forResource: "selectedFileName", ofType: "mp4")
    if let filepath = filepath {
        let fileURL = URL.init(fileURLWithPath: filepath)
        player = AVPlayer(url: fileURL)
        let playerLayer = AVPlayerLayer(player: player)
        // Register for notification
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(playerItemDidReachEnd),
                                                         name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
                                                         object: nil) // Add observer

        playerLayer.frame = self.view.bounds
        self.view.layer.addSublayer(playerLayer)
        player.play()
    }
}
// Notification Handling
@objc func playerItemDidReachEnd(notification: NSNotification) {
    player.seek(to: CMTime.zero)
    player.play()
}
// Remove Observer
deinit {
    NotificationCenter.default.removeObserver(self)
}

对于SWIFT 3.0这很好

class PlayVideoViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(PlayVideoViewController.finishVideo), name: NSNotification.Name.AVPlayerItemDidPlayToEndTimeNotification, object: nil)
    }

    func finishVideo()
    {
        print("Video Finished")
    }
}

Swift 4.0

这对我有用。 感谢@Channel

    private func playVideo(fileURL: String) {

            // Create RUL object
            let url = URL(string: fileURL)

            // Create Player Item object
            let playerItem: AVPlayerItem = AVPlayerItem(url: url!)
            // Assign Item to Player
            let player = AVPlayer(playerItem: playerItem)

            // Prepare AVPlayerViewController
            let videoPlayer = AVPlayerViewController()
            // Assign Video to AVPlayerViewController
            videoPlayer.player = player

            NotificationCenter.default.addObserver(self, selector: #selector(myViewController.finishVideo), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: nil)

            // Present the AVPlayerViewController
            present(videoPlayer, animated: true, completion: {
                    // Play the Video
                    player.play()
            })

    }

    @objc func finishVideo()
    {
            print("Video Finished")
    }

    //Called when player finished playing

对于SWIFT 3.0

这里的“ fullUrl”是视频的URL,并确保URL中没有空格。您应将“ Space”替换为“%20”,以便URL可以正常工作。

  let videoURL = NSURL(string: fullUrl)
  let player = AVPlayer(url: videoURL! as URL)

  playerViewController.delegate = self
  playerViewController.player = player
  self.present(playerViewController, animated: false) {

    self.playerViewController.player!.play()

    NotificationCenter.default.addObserver(self, selector: #selector(yourViewControllerName.playerDidFinishPlaying), name: Notification.Name.AVPlayerItemDidPlayToEndTime, object: self.player?.currentItem)
  }

在视图控制器中的给定方法下面添加此方法。

func playerDidFinishPlaying(){    
print("Video Finished playing in style")
}

在Swift 3和RxSwift 3.5中,您要做的就是:

override func viewDidLoad() {
    super.viewDidLoad()

    NotificationCenter.default.rx.notification(Notification.Name.AVPlayerItemDidPlayToEndTime)
        .asObservable().subscribe(onNext: { [weak self] notification in

            //Your action

        }).addDisposableTo(disposeBag)
}

我知道这里有很多公认的答案...

但是,另一种方法可能是向AVPlayer添加边界时间观察者。 您必须具有视频的时长,可以从player.currentItem中获取视频的时长,然后将其添加为所需的时间范围。

fileprivate var videoEndObserver: Any?

func addVideoEndObserver() {
    guard let player = YOUR_VIDEO_PLAYER else { return }

    // This is just in case you are loading a video from a URL.
    guard let duration = player.currentItem?.duration, duration.value != 0 else {
        DispatchQueue.main.asyncAfter(deadline: .now() + 0.5, execute: { [weak self] in
            self?.addVideoEndObserver()
        })

        return
    }

    let endTime = NSValue(time: duration - CMTimeMakeWithSeconds(0.1, duration.timescale))
    videoEndObserver = player.addBoundaryTimeObserver(forTimes: [endTime], queue: .main, using: {
        self.removeVideoEndObserver()

        // DO YOUR STUFF HERE...
    })
}

func removeVideoEndObserver() {
    guard let observer = videoEndObserver else { return }

    videoPlayer.player?.removeTimeObserver(observer)
    videoEndObserver = nil
}

真的很简单

    NotificationCenter.default.addObserver(
        self,
        selector: #selector(fileComplete),
        name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
        object: nil)

(该对象可以为零。)

然后

@objc func fileComplete() {
    print("IT'S DONE!")
}
