我正在处理丰富的通知的Notification Content Extension，并且能够成功加载images和gif，如以下屏幕截图所示:
现在，我正在尝试播放视频，并且正在执行以下代码来播放视频。
- (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。但是那不会玩。如果有人有该解决方案，请提供帮助。
谢谢。
最佳答案
我对代码犯了一个很小的错误。如果我做如下代码，我们必须检查startAccessingSecurityScopedResource
- (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。 ......
