objective c - How do I disable NSLog?

I'd like to do the following in Xcode:

Find all NSLog commands without comments, and replace it with //NSLog...

In other words, I want to comment all NSLog calls. Is this possible? Is there an easy way to do this?

wait there is far more simple method. Just add the following lines when you dont need NSLOG to your constants file

#define NSLog                       //

and comment it when you need it.

EDIT: In latest Xcode, you get error on above statement. So I figured out the best way is

#define NSLog(...)
