UPDATE Check out JSCocoa, a bridge from Javascript to Cocoa. It uses libffi to call ObjC, C, use C structs, and define your own classes. If you need FFI sample code check out the JSCocoa source.

libffi can call any function provided you know its definition. (Thanks BridgeSupport !)

Compiling

Define MACOSX or libffi will bail with #error "Unsupported OS type".

#define MACOSX
#import <ffi/ffi.h>

Linking

To your project's build configuration, add -lffi as Other Linker Flags.

Sample usage

Get the source and check the folder testsuite/libffi.call.

There you go ! Quick post because I had trouble using it, it's the first time I link to a library. Frameworks are easier as you can drag and drop them.
