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

From within Xcode:

• Xcode 3: Select the file, then Build → Preprocess.
• Xcode 4: Select the file, then Product → Generate Output → Generate Preprocessed File.
