How i can get list of user playlists from code? In CocoaT开发者_运维问答ouch.

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);

This is solution:

MPMediaQuery *playlistsQuery = [MPMediaQuery playlistsQuery];
NSArray *playlists = [playlistsQuery collections];
