推荐答案

您可以通过调用MPNowPlayingInfoCenter更改正在播放的标签的文本，这还允许您修改歌曲名称，专辑，艺术家和专辑插图在锁定屏幕上.

You can change the text of the now playing label by calling the MPNowPlayingInfoCenter, this will also allow you to modify the song name, album, artist, and album artwork on the lock screen.

#import <MediaPlayer/MPNowPlayingInfoCenter.h>
#import <MediaPlayer/MPMediaItem.h>

MPMediaItemArtwork *albumArt;


- (void)changeTrackTitles
{
  Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter");

    if (playingInfoCenter) 
    {
        albumArt = [[MPMediaItemArtwork alloc] initWithImage: [UIImage imageNamed:@"HexagonArtwork"]];
        NSMutableDictionary *songInfo = [[NSMutableDictionary alloc] init];
        [songInfo setObject:@"SongName" forKey:MPMediaItemPropertyTitle];
        [songInfo setObject:@"AlbumName" forKey:MPMediaItemPropertyAlbumTitle];
        [songInfo setObject:@"ArtistName" forKey:MPMediaItemPropertyArtist];
        [songInfo setObject:albumArt forKey:MPMediaItemPropertyArtwork];
        [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:songInfo];
    }
}
