我正在处理富通知的 Notification Content Extension
,并且能够成功加载 images
和 gif
,如下图所示:
现在我正在尝试播放视频,并且正在执行以下播放代码。
- (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 中我也得到了视频的文件 url。但那不会玩。如果有人有该解决方案,请提供帮助。
谢谢。
最佳答案
这是我用那个代码做的非常小的错误。我们必须检查 startAccessingSecurityScopedResource
如果我执行如下代码
- (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。呜呜……
关于ios - 丰富的推送通知 - 视频不会在通知内容扩展中播放,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/42579421/
