Setting a flag in compiler for NSLog not to show

Question

Is there any particular flag which can be set to not display NSLog output in either debug or release?

Thanks.

One option might be to use a macro as a replacement for NSLog (if its easy for you to change things at this point). I like the prefix header file these guys use:

http://www.cimgf.com/2010/05/02/my-current-prefix-pch-file/

Basically their logging function is:

#ifdef DEBUG
  #define DLog(...) NSLog(@"%s %@", __PRETTY_FUNCTION__, [NSString stringWithFormat:__VA_ARGS__])
#else
  #define DLog(...) do { } while (0)
#endif

So if you are not in a DEBUG build, the logging macro becomes a no-op.
