MPMusicPlayerController随机歌曲

Question

我有这个代码用于选择和播放ipod歌曲

- (void)mediaPicker: (MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection{
[self dismissViewControllerAnimated:YES completion:nil];
[riproduttore setQueueWithItemCollection: mediaItemCollection];
[riproduttore play];

}

如何在没有pikerview的情况下加载随机歌曲？

实施例。 rnd 1到100，result = 66，我可以在ipod库中播放索引为66的歌曲

Answer 1

尝试这样的事情：

MPMediaQuery* query = [MPMediaQuery songsQuery]; 
NSArray *songs = [query items];
MPMediaItem *randomTrack = [songs objectAtIndex:arc4random_uniform([songs count])];
// ... and then play with MPMediaPlayer, AVPlayer, etc.
