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.

Generally, people write their own macro -- something like DebugLog -- for logs to be "compiled out":

#undef DebugLog
#ifdef DEBUG_MODE
#define DebugLog( s, ... ) NSLog( @"%@", [NSString stringWithFormat:(s), ##__VA_ARGS] )
#else
#define DebugLog( s, ... )
#endif
