Honestly, I can't say I fully agree---having full symbol information for
every method/function in a program makes reverse-engineering much, much
simpler.

However, if it is important to you, you can get a lot of mileage out of
strategic #defines to rename your classes, methods and categories to
meaningless names. Obviously you can't do this if you are implementing
delegate methods or subclassing built-in methods, but you can still
obscure your tracks relatively well. e.g. imagine a header, included
everywhere, that did:

#define MyBigClass _1
#define MyOtherClass _2
#define updateMyObject _3
#define withSomeOtherValue _4
#define myInfo a0
#define setMyInfo setA0
#define otherInfo a1
#define setOtherInfo setA1

etc.
I've never actually done this in ObjC but I've done it with C and had
good results. I guess the biggest constraint is that you have to still
honor KVO/KVC naming conventions, etc., so you'll still need "set" in
front of some names.
