I have hundreds of NSLog statelements in my project which I would like to see not executing in the release version. Long time back I read that a way to do it is to define a macros specifically for the debug mode. I don't remember it any longer. Can someone tell me whats the best way to avoid hundreds of lines of code, useless in the release version?

Do a gang find/replace via Xcode and comment them out.
I use this macro in my .pch file
#ifdef DEBUG
#define DLog( s, ... ) NSLog( @"<%p %@:(%d)> %@", self, [[NSString stringWithUTF8String:__FILE__] lastPathComponent], __LINE__, [NSString stringWithFormat:(s), ##__VA_ARGS__] )
#else
#define DLog( s, ... )
#endifThat's for Objective-C of course. No idea where I got it from.
I came accross this on quora. But wasnt able to understand how it works. Can u explain?
Instead of writing "NSLog(some stuff)" in your code, you write "DLog(some stuff)". Same syntax. Then at compile time, the preprocessor either replaces that with a nicely formatted NSLog() call, or omits the whole thing, depending on whether the DEBUG flag is set. By default I believe it is not set for release builds. You can control it using build schemes.
Are you using Swift, or Objective-C? This is obviously an Objective-C solution.
“at compile time, the preprocessor either replaces that with a nicely formatted NSLog() call, or omits the whole thing, depending on whether the DEBUG flag is set. By default I believe it is not set for release builds” I read the same on quora. Is it possible to. Not have to replace hundreds of these NSLogs with Dlog?
