如何从ipod图书馆歌曲的歌曲歌词

Question

我正在访问iphone应用程序中的ipod库并显示专辑的标题，歌词和艺术品。我还想展示歌曲的歌词。我在itunes中添加了歌词，并与设备同步。但是我的代码没有显示歌词…

从这里的例子和代码来获得歌词是:-

- (void)handleNowPlayingItemChanged:(id)notification {
    // Ask the music player for the current song.
    MPMediaItem *currentItem = self.musicPlayer.nowPlayingItem;
    // Display the artist, album, and song name for the now-playing media item.
    // These are all UILabels.
    self.songLabel.text   = [currentItem valueForProperty:MPMediaItemPropertyTitle];
    self.artistLabel.text = [currentItem valueForProperty:MPMediaItemPropertyAlbumArtist];
    self.albumLabel.text  = [[currentItem valueForProperty:MPMediaItemPropertyLyrics]retain];    

}

请帮助。由于

NSURL* songURL = [mediaItem valueForProperty:MPMediaItemPropertyAssetURL] 
AVAsset* songAsset = [AVURLAsset URLAssetWithURL:songURL options:nil]; 
NSString* lyrics = [songAsset lyrics];
