if (!artwork)
- (void)handleNowPlayingItemChanged:(id)notification {
MPMediaItem *item = self.musicPlayer.nowPlayingItem;
CGSize albumCoverSize = self.albumCover.bounds.size;
MPMediaItemArtwork *artwork =
[item valueForProperty:MPMediaItemPropertyArtwork];
if (artwork) {
self.albumCover.image = [artwork imageWithSize:albumCoverSize];
} else {
self.albumCover.image = nil;
}
}

MPMediaItemArtwork *artworkItem = [self.musicPlayer.nowPlayingItem valueForProperty: MPMediaItemPropertyArtwork]; if ([artworkItem imageWithSize:CGSizeMake(320, 320)]) { [self.currentlyPlayingArtworkView setImage:[artworkItem imageWithSize:CGSizeMake (320, 320)]]; } else { [self.currentlyPlayingArtworkView setImage:[UIImage imageNamed:@\"NoArtworkImage\"]]; }babsoft
