Objective-C Code Obfuscation

I am trying to build an iOS package that can be reused in multiple applications. I would like to be able to link it for others to easily insert and use, and I would like to confuse the code so that no one can read it.

What would you recommend between creating a framework, a static library, or another solution for this, and why?
