在 NSNotificationCenter 和 playerItemDidReachEnd 的帮助下，我循环播放了使用 AVFoundation 视频播放的视频：

    AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
    self.playerItem = [AVPlayerItem playerItemWithAsset:asset];
    self.avPlayer = [AVPlayer playerWithPlayerItem:self.playerItem];

    [self.avPlayer      addObserver:self forKeyPath:@"status"
                        options:0 context:AVMoviePlayerViewControllerStatusObservationContext];
    [[NSNotificationCenter defaultCenter]           addObserver:self
                                                    selector:@selector(playerItemDidReachEnd:)
                                                    name:AVPlayerItemDidPlayToEndTimeNotification
                                                    object:[self.avPlayer currentItem]];

    [self.VideoView setPlayer:self.avPlayer];

和

- (void)playerItemDidReachEnd:(NSNotification *)notification {        
        [notification.object seekToTime:kCMTimeZero];
        [self startVideoLoop];
}

效果很好 - 但不幸的是不可靠。有时没有任何逻辑原因（在我看来）播放器在电影结束时停止而没有再次重新启动。

NSNotificationCenter 是否有可能错过了电影的结尾或方法 playerItemDidReachEnd 错过了通知消息？愚蠢的问题。但我无法确定它的头或尾......

答案是

self.avPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone;  // default: AVPlayerActionAtItemEndPause
