How to detect if an MPMediaItem represents a DRM-protected audio track on iOS

Question

I would like to know if an MPMediaItem that represents a music track is for a Fairplay/DRM-protected item. Any way to do this?

Answer 1

From iOS 4.2 the AVAsset class has a property hasProtectedContent so you can check:

NSURL *assetURL = [item valueForProperty:MPMediaItemPropertyAssetURL];
AVAsset *asset = [AVAsset assetWithURL:assetURL];

if ([asset hasProtectedContent] == NO) {..do your stuff..}
