How to protect resources for .ipa file

Hi,

We know that the security issue is a big problem for apple. Anyone can access your resources, including images and sounds,

by using a tool such as iPhone Explorer to connect to your device. However, I saw some compressed(or encrypted) resources

in a .ipa and nobody could get those resources. Does anyone know how to protected resources and load the compressed resources

dynamically in a game ?

One approach:
