conditional compilation warning for constant

QUESTION

I would like to trigger a warning only if my TESTING is YES. Is this possible? What I have now doesn't work. What should I do?

BOOL const TESTING = NO;
#if TESTING == YES
    #warning don't forget to turn testing to NO before upload
#endif

ANSWER

Based on the answer below, here is what worked for me:

#define _TESTING // COMMENT THIS OUT TO DISABLE TESTING MODE
#ifdef _TESTING
    BOOL const TESTING = YES;
    #warning don't forget to turn testing to NO for production
#else
    BOOL const TESTING = NO;
#endif

Try replacing what you have with 

#ifdef TESTING
  #warning //... warning here
  BOOL const testingBool = YES;
#else
  BOOL const testingBool = NO;
#endif

Then, you need to add TESTING as a "Preprocessor Macro" in your Target's Build Settings (see this question for more details on how to do that).
