  • 0

I am trying to create a very simple music player (for small children) in Monotouch and have most of it working just great.

However when I iterate through MPMediaItems in a playlist and try to get their artwork I always get an image with size 55 x 55 pixels. When I listen to the songs in the builtin IPod application I can see that the stored artwork is larger than that.

Platform: Latest monodevelop and monotouch. iOS 4.2.3 on device

Code to get artwork of the first song in a playlist:

MPMediaItem[] songs = foundPlaylist.Items;
MPMediaItemArtwork artwork = (MPMediaItemArtwork)songs[0].ValueForProperty(MPMediaItemProperty.Artwork);
var imageRect = artwork.ImageCropRectangle;
UIImage artWorkImage = artwork.ImageWithSize (imageRect);

Am pretty stumped here. Any ideas?

Best regards

Soren

    Oki, got it figured out.
    Big thanks to Kangaroo on the monotouch chat!

    There is a binding error in the imageWithSize method on MPMediaItemArtwork, so you need to message the selector directly. This is done in this way (to get a 256×256 image):

    UIImage artWorkImage = (UIImage) Runtime.GetNSObject (Messaging.IntPtr_objc_msgSend_SizeF (artwork.Handle, Selector.GetHandle ("imageWithSize:"), new SizeF (256, 256)));
