In my iphone project i have a set of 20 mp3 audio files in it.now the whole project is working fine.
but client has come up with a problem that whenever he installs the app file ,the mp3 files get added to the itunes list..
this should not occur as these should be bought only by inapp purchase...
I had added all mp3 files into the xcode app bundle itself.(by dragging into the resources folder)
Should anything else be done so that mp3 files stay in app itself?
If I understand you right, you have 20 .mp3 files in your app bundle, which can be unlocked by inApp purchase? This is far to easy to crack, as one can just look into the bundle and extract the files, as a bundle is basically a folder.
I can't post a complete solution, but consider encrypting the files and set up a web service, which delivers a token to unlock the files after being purchased via inApp purchase.
