丰富推送通知 - 视频无法在通知内容扩展中播放

Question

我正在处理丰富的通知Notification Content Extension,并且能够加载images并gif成功地喜欢以下屏幕截图:

现在我正在尝试播放视频,我正在按照代码播放它.

- (void)didReceiveNotification:(UNNotification *)notification {
    //self.label.text = @"HELLO world";//notification.request.content.body;

    if(notification.request.content.attachments.count > 0)
    {

        UNNotificationAttachment *Attachen = notification.request.content.attachments.firstObject;


        NSLog(@"====url %@",Attachen.URL);
        AVAsset *asset = [AVAsset assetWithURL:Attachen.URL];
        AVPlayerItem *item = [AVPlayerItem playerItemWithAsset:asset];

        AVPlayer  *player = [AVPlayer playerWithPlayerItem:item];
        AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
        playerLayer.contentsGravity = AVLayerVideoGravityResizeAspect;
        player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
        playerLayer.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);

            [self.VideoPlayerView.layer addSublayer:playerLayer];
        [player play];
    }
}

在NSLog中,我也获得了视频的文件URL.但那不会玩.如果任何人有这个解决方案,请帮助.

谢谢.

我在代码中犯了一个非常小的错误。我们必须检查startAccessingSecurityScopedResource我是否执行如下代码

- (void)didReceiveNotification:(UNNotification *)notification {

    if(notification.request.content.attachments.count > 0)
    {
            UNNotificationAttachment *Attachen = notification.request.content.attachments.firstObject;

            if(Attachen.URL.startAccessingSecurityScopedResource)
            {

                NSLog(@"====url %@",Attachen.URL);
                AVAsset *asset = [AVAsset assetWithURL:Attachen.URL];
                AVPlayerItem *item = [AVPlayerItem playerItemWithAsset:asset];

                AVPlayer  *player = [AVPlayer playerWithPlayerItem:item];
                AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
                playerLayer.contentsGravity = AVLayerVideoGravityResizeAspect;
                player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
                playerLayer.frame = CGRectMake(0, 0, self.VideoPlayerView.frame.size.width, self.VideoPlayerView.frame.size.height);

                [self.VideoPlayerView.layer addSublayer:playerLayer];
                [player play];

            }                
        }
}

视频正在播放。嘘……
