Question

我已经搜索了所有关于airplay的设置歌曲信息，看起来很简单，但我仍然无法使我的应用程序正常运行。
我使用MPMoviePlayerController播放音频。我还在developer.apple.com上阅读了AirPlay概述。

我在视图中设置了以下代码

- (BOOL) canBecomeFirstResponder {return YES;}
- (void) viewDidAppear: (BOOL) animated {
    [super viewDidAppear:animated];
    [ [UIApplication sharedApplication] beginReceivingRemoteControlEvents];
    [self becomeFirstResponder];
}
- (void) remoteControlReceivedWithEvent: (UIEvent *) receivedEvent {
    if (receivedEvent.type == UIEventTypeRemoteControl) {
        switch (receivedEvent.subtype) {
            case UIEventSubtypeRemoteControlTogglePlayPause:
               // [self playPauseToggle: nil]
                break;
            case UIEventSubtypeRemoteControlNextTrack:
                [self nextTrack: nil]
                break;
     }
}

并且在播放音乐之前设置了nowplayinginfo（在播放音乐之后尝试设置了这个）

NSMutableDictionary *airPlaySongInfo = [[NSMutableDictionary alloc]init];
        [airPlaySongInfo setObject:@"hihi title"] forKey:MPMediaItemPropertyTitle];
        [airPlaySongInfo setObject:@"hihi artist"forKey:MPMediaItemPropertyArtist];
        [airPlaySongInfo setObject:@"hihi album" forKey:MPMediaItemPropertyAlbumTitle];
        [airPlaySongInfo setObject:albumArt forKey:MPMediaItemPropertyArtwork];
        [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:airPlaySongInfo];

我已经设置了在plist中播放音频的背景模式但我的电视上没有标题，艺术家和专辑信息。我错过了什么？或者有什么冲突？

设置nowplayingInfo显示歌曲标题，艺术家在airplay（苹果电视），不工作
