iOS上获取iTunes音乐权限

方法一：

MPMediaQuery *mysongsQuery = [MPMediaQuerysongsQuery];

    _songsArray = [mysongsQuery items];

    

    for (MPMediaItem *songin _songsArray) {

        NSString *songTitle = [songvalueForProperty:MPMediaItemPropertyTitle];

        NSString *assetUrl = [songvalueForProperty:MPMediaItemPropertyAssetURL];

        NSLog (@"%@ %@", songTitle,assetUrl);

    }

    

    MPMediaQuery *playlistQuery = [MPMediaQueryplaylistsQuery];

    for (MPMediaPlaylist *playlistin playlistQuery.items)

    {

        NSString *playlistName = [playlistvalueForProperty:MPMediaPlaylistPropertyName];

        NSLog (@"%@", playlistName);

    }

    

    MPMediaQuery *albumQuery = [MPMediaQueryalbumsQuery];

方法二：

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

        vc.delegate = self;

        [selfpresentViewController:vc animated:YEScompletion:^{

            

        }];

并实现代理方法：

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

{

    MPMediaItem *item = mediaItemCollection.items.firstObject;

    NSString *songTitle = [itemvalueForProperty:MPMediaItemPropertyTitle];

    NSURL *assetUrl = [itemvalueForProperty:MPMediaItemPropertyAssetURL];

    NSLog (@"%@ %@", songTitle,assetUrl);

    

    [mediaPicker dismissViewControllerAnimated:YEScompletion:^{

        

    }];

    

    MPMusicPlayerController* mDRMAudioPlayer = [MPMusicPlayerControllerapplicationMusicPlayer];

    [mDRMAudioPlayer setQueueWithItemCollection:mediaItemCollection];

    [mDRMAudioPlayer play];

}

- (void)mediaPickerDidCancel:(MPMediaPickerController *)mediaPicker

{

    [mediaPicker dismissViewControllerAnimated:YEScompletion:^{

        

    }];

}
