Question

I have tried AVPlayer for playing online http streamed music file, it works fine.

What is the way to get the current playing audio track name,artist etc?
Is there any way to adjust the volume of AVPlayer while playing music (using UISlider )?

Answer 1

您可以通过以下方式调节音量：

player.volume = slider.value;

Answer 2

MPMediaItem *currentItem = self.musicPlayer.nowPlayingItem;

//Display the artist, album, and song name for the now-playing media item.
//These are all UILabels.
self.songLabel.text   = [currentItem valueForProperty:MPMediaItemPropertyTitle];
self.artistLabel.text = [currentItem valueForProperty:MPMediaItemPropertyArtist];
self.albumLabel.text  = [currentItem valueForProperty:MPMediaItemPropertyAlbumTitle];
