ios - 如何获取在 MPMediaPickerController 中选择的播放列表的名称

Question

    MPMediaQuery *myPlaylistsQuery = [MPMediaQuery playlistsQuery];
    NSArray *playlists = [myPlaylistsQuery collections];
    for (MPMediaPlaylist *playlist in playlists) {
        NSLog (@"%@", [playlist valueForProperty: MPMediaPlaylistPropertyName]);
        NSArray *songs = [playlist items];
        for (MPMediaItem *song in songs) {
            NSString *songTitle = [song valueForProperty: MPMediaItemPropertyTitle];
            NSLog (@"\t\t%@", songTitle);
        }
    }

此代码仅提供所有播放列表和歌曲的名称，但我想获取用户从中选择歌曲的播放列表的名称。
