Is there any way to obfuscate Objective-C Code ?
Thanks
The selectors are still plaintext - otool -o will dump out all your objects and the methods they define. You can also dump out all internal and external selectors accessed in the code with a one-liner that follows. Obfuscating method and parameter names at the source level would probably be easiest, though doing it at the object level will also obfuscate in a language-independent way at the expense of some linker table manipulation.
otool -s __TEXT __objc_methname yourapp.app/executable_file |expand -8 | cut -c17- | sed -n 3,$p | perl -n -e print join("
",split(/x00/,scalar reverse (reverse unpack("(a4)*",pack("(H8)*",split(/s/,$_)))))) |less
Objective c is a straight superset of C, therefore all normal C obfuscation techniques work. If you want to work with cocoa, however, you re going to have a bit of an obstacle because the method names are fairly self-documenting.
For your own methods, you just have to self-document the methods incorrectly. e.g.
-(void) doSomethingInnocent:(BOOL)animated withObject:passwords;
when you would normally have written:
-(void) sendObjectToMyServer:(BOOL)coverupAnimation;
