我怎么知道AVPlayer视频何时结束？

Question

场景：iOS设备在进入AVPlayerViewController时通过AVPlayer自动播放视频。

如何检测AVPlayer何时完成？

Answer 1

当玩家项目完成播放时，您可以注册接收AVPlayerItemDidPlayToEndTimeNotification通知。

NSNotificationCenter.defaultCenter().addObserver(self, selector: "playerItemDidReachEnd:", name: AVPlayerItemDidPlayToEndTimeNotification, object: self.playerItem)

Answer 2

以防它帮助某人。我知道它在Obj-C中，但我不得不将其添加到一些旧代码中;）

- (void)setupVideo {

    NSString *stringVideoName = @"myVideo.mp4";
    NSString *stringVideoPath = [[NSBundle mainBundle] pathForResource:stringVideoName ofType:nil];

    NSURL *urlVideoFile = [NSURL fileURLWithPath:stringVideoPath];

    _playerViewController = [[AVPlayerViewController alloc] init];
    _playerViewController.player = [AVPlayer playerWithURL:urlVideoFile];
    _playerViewController.view.frame = self.videoView.bounds;
    _playerViewController.showsPlaybackControls = YES;

    // Identify when the player time position jumps.
    [NSNotificationCenter.defaultCenter addObserver:self selector:@selector(playerItemTimeJumped:) name:AVPlayerItemTimeJumpedNotification object:_playerViewController.player.currentItem];

    [self.videoView addSubview:_playerViewController.view];
    self.videoView.autoresizesSubviews = YES;
}

- (void)playerItemTimeJumped:(NSNotification*)notification {
    AVPlayerItem *playerItem = notification.object;

    if (playerItem.status == AVPlayerItemStatusReadyToPlay) {
        [NSNotificationCenter.defaultCenter removeObserver:self name:AVPlayerItemTimeJumpedNotification object:notification.object];
// The video play button has been pressed only once. Tell someone about it.
        }
    }

Swift 4.0

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