What, exactly, are you trying to do?

The Obj-C runtime supports introspection and you can grab the method 
signature and then rip it apart to deduce parameter and return 
types.  To a degree;  you lose with complex C types and certain other 
parameter types.

I would suggest poking through the source code for one of the various 
Obj-C bridges to see the full details;  PyObjC, F-Script (Smalltalk-
esque), RubyCocoa, and CamelBones (Perl-ObjC) all introspect to do 
cross language method dispatches.
