ios – 显示Spotify现在在控制中心播放项目信息

2023年5月4日 252次阅读

我在我的iOS应用程序中使用了新的Spotify SDK.在这里,我使用以下代码播放Spotify中的歌曲.我能够播放这首歌.但我无法看到正在播放的项目歌曲信息,无法控制iOS控制中心的歌曲.我需要将歌曲信息更新到控制中心.

[SPTTrack trackWithURI:appDelegate.player.currentTrackURI
               session:auth.session
              callback:^(NSError *error, SPTTrack *track) {

                  self.trackTitle.text = track.name;

                  SPTPartialArtist *artist = [track.artists objectAtIndex:0];
                  self.trackArtist.text = artist.name;

                  appDelegate.currentPlayingSongName = track.name;
                  appDelegate.currentPlayingArtistName = artist.name;

                  //[MPNowPlayingInfoCenter defaultCenter].nowPlayingInfo = [NSDictionary dictionaryWithObject:track.name forKey: MPMediaItemPropertyTitle];

                  Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter");

                  if (playingInfoCenter) {

                      NSMutableDictionary *songInfo = [[NSMutableDictionary alloc] init];

                      [songInfo setObject:@"Audio Title" forKey:MPMediaItemPropertyTitle];
                      [songInfo setObject:@"Audio Author" forKey:MPMediaItemPropertyArtist];
                      [songInfo setObject:@"Audio Album" forKey:MPMediaItemPropertyAlbumTitle];
                      [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:songInfo];


                  }

}];

感谢您阅读我的问题.提前致谢

最佳答案 我发现你的帖子时,我昨天正在查找相同的信息.从那以后我就弄明白了.但这很快.我刚开始学习xcode和swift.所以不知道如何在objc中翻译它.希望这可以帮助 😉

//show now playing info:

var player: SPTAudioStreamingController?
let songInfo = [
                MPMediaItemPropertyTitle:  self.player!.currentTrackMetadata[SPTAudioStreamingMetadataTrackName] as! String,
                MPMediaItemPropertyArtist: self.player!.currentTrackMetadata[SPTAudioStreamingMetadataArtistName] as! String,
                MPMediaItemPropertyArtwork: albumArt,
                MPNowPlayingInfoPropertyElapsedPlaybackTime: self.player!.currentPlaybackPosition,
                MPMediaItemPropertyPlaybackDuration: self.player!.currentTrackDuration,
                MPNowPlayingInfoPropertyPlaybackRate:  1.0
            ]
            MPNowPlayingInfoCenter.defaultCenter().nowPlayingInfo = songInfo


//setup and receive remote control events:

UIApplication.sharedApplication().beginReceivingRemoteControlEvents()

// then 

override func remoteControlReceivedWithEvent(event: UIEvent?) {
    if event!.type == UIEventType.RemoteControl {
        if event!.subtype == UIEventSubtype.RemoteControlPlay {
            togglePlay()
//etc...
