Obj C and class-dump protection

Question

I understand that it is easy to hack Mach-O executable, I just want simple protection against "class-dump" tool. Is there any tool or XCode plugin that can change all classes names and class functions to something not very readable (like random combination of symbols and numbers)?

Frankly that's all protection I need.

Answer 1

I wrote a bit about this in this blog post, but to summarise: you can avoid having methods appearing in class-dump by registering them at runtime, or just keeping them as functions.

If really all you want to do is rename the classes/methods, you can use the tops command-line tool or Xcode's refactoring feature.

Answer 2

Are you looking for Objective C obfuscators?

This page has a great discussion on Obfuscating Cocoa.
