[self presentViewController:picker animated:YES completion:^(void) {}];
}

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


if (mediaItemCollection)

    NSMutableArray *medialibraryArray;
    medialibraryArray=[[NSMutableArray alloc]init];
    [medialibraryArray addObject:mediaItemCollection.items];// Modified

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

    if (mediaItemCollection)
    {
        NSArray *items = [mediaItemCollection items];
        for( int n=0; n < items.count; n++ )    {
            MPMediaItem *mediaItem = [items objectAtIndex:n];
            NSLog(@"%@=========>",[mediaItem valueForProperty:MPMediaItemPropertyTitle]);
        }

        MPMusicPlayerController *musicPlayer = [MPMusicPlayerController iPodMusicPlayer];
        [musicPlayer setQueueWithItemCollection: mediaItemCollection];
        NSLog(@"==>%@",musicPlayer);


    }
    [self dismissViewControllerAnimated:YES completion:^(void) {}];
}

您将使用它来获取库中的所有歌曲，因此打印输出可能需要一段时间！阅读 MPMediaItem 类参考和媒体查询，了解如何获取整个音乐库的子集。
