I'm not sure what is faster.  A full parser for Objective-C should include
a full parser for C -- I actually expect the C parser to be most of the
work.  So maybe you want to start from some free software C parser on the
net, and just extend it to support Objective-C.

I believe NeXT/Apple's manual on Objective-C (available free on the web)
contains a grammar for Objective-C at the end.  I'd say that the
definitive source is actually the GCC bison grammar itself.

Hope that helps.
