Programmatically determine active configuration

Question

Is there a way to determine the active configuration (that means Debug or Release) in code? Something along the lines of

#ifdef XCodeConfigurationDebug
    ...  
#endif  

#ifdef XCodeConfigurationRelease
    ...  
#endif  

I know that it's possible to do this by adding custom compiler flags. However, I'm looking for a more global solution.

Answer 1

i figure it out using the preprocessor declarations. you can add your own definition, or NDEBUG is another common one to declare in release.

Answer 2

There is the flag __OPTIMIZE__ that is defined when on RELEASE mode, and so:

#ifndef __OPTIMIZE__
// code for debug mode
#else
// code for release
#endif
