IPod Library Path to NSData

Question

How to convert iPod library to NSData. Url:

ipod-library://item/item.mp3?id=1258203422631791096 

Getting error, but I can play the song using AVPlayer.

  NSURL *url = [curItem valueForProperty: MPMediaItemPropertyAssetURL]; NSError *error = nil; NSData *data = [NSData dataWithContentsOfFile:[url absoluteString] options:NSDataReadingMappedAlways error:&error]; NSLog(@"Error : %@",error); 

curItem is MPMediaItem

 Error Domain=NSCocoaErrorDomain Code=260 "The file "item.mp3?id=1258203422631791096" couldn't be opened because there is no such file." UserInfo={NSFilePath=ipod-library://item/item.mp3?id=1258203422631791096, NSUnderlyingError=0x15ff23420 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}

You cannot access the URL of the media content directly, as it is located outside the application sandbox.

You need to get the asset using AVAssetExportSession, which saves it to a URL in your sandbox. You can get NSData from here - see this SO iOS 6 question . Convert MPMediaItem to NSData
