C, Objective-C preprocessor output

Question

Is there a way to get pre-processed C/Objective-C code? I have some files I acquired and would like to see the code produced by some #defines.

Answer 1

On the command line, gcc -E foo.m will show you the preprocessed output (just as it does for normal C/C++ files). Of course, this will also expand any #include or #import statements you may have in your code.
