方法一：

MPMediaQuery *mysongsQuery = [MPMediaQuery songsQuery];

_songsArray = [mysongsQuery items];

for (MPMediaItem *song in _songsArray) {

NSString *songTitle = [song valueForProperty:MPMediaItemPropertyTitle];

NSString *assetUrl = [song valueForProperty:MPMediaItemPropertyAssetURL];

NSLog (@"%@ %@", songTitle,assetUrl);

}

MPMediaQuery *playlistQuery = [MPMediaQuery playlistsQuery];

for (MPMediaPlaylist *playlist in playlistQuery.items)

{

NSString *playlistName = [playlist valueForProperty:MPMediaPlaylistPropertyName];

NSLog (@"%@", playlistName);

}

MPMediaQuery *albumQuery = [MPMediaQuery albumsQuery];

方法二：

MPMediaPickerController *vc = [[MPMediaPickerController alloc] initWithMediaTypes:MPMediaTypeMusic];

vc.delegate = self;

[self presentViewController:vc animated:YES completion:^{

}];

并实现代理方法：

- (void)mediaPicker:(MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection*)mediaItemCollection

{

MPMediaItem *item = mediaItemCollection.items.firstObject;

NSString *songTitle = [item valueForProperty:MPMediaItemPropertyTitle];

NSURL *assetUrl = [item valueForProperty:MPMediaItemPropertyAssetURL];

NSLog (@"%@ %@", songTitle,assetUrl);

[mediaPicker dismissViewControllerAnimated:YES completion:^{

}];

MPMusicPlayerController* mDRMAudioPlayer = [MPMusicPlayerController applicationMusicPlayer];

[mDRMAudioPlayer setQueueWithItemCollection:mediaItemCollection];

[mDRMAudioPlayer play];

}

- (void)mediaPickerDidCancel:(MPMediaPickerController *)mediaPicker

{

[mediaPicker dismissViewControllerAnimated:YES completion:^{

}];

}
