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.
