[英]How do I know when an AVPlayer video has ended?
場景:iOS設備在進入AVPlayerViewController后自動通過AVPlayer播放視頻。
如何檢測AVPlayer何時完成?
您可以注冊以在播放器項目完成播放后接收AVPlayerItemDidPlayToEndTimeNotification
通知。
NSNotificationCenter.defaultCenter().addObserver(self, selector: "playerItemDidReachEnd:", name: AVPlayerItemDidPlayToEndTimeNotification, object: self.playerItem)
以防萬一它可以幫助某人。 我在Obj-C中知道它,但是我不得不將其添加到一些舊代碼中;)
- (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.
}
}
