In Xcode, you can use Find and Replace and provide a regular expression something like:

NSLog.*;

Put this in your prefix header......

   #ifndef __OPTIMIZE__

    #    define NSLog(...) NSLog(__VA_ARGS__)

      #else

     #    define NSLog(...) {}

      #endif

This method is MUCH more useful than NSLog.*; because I can keep all my logs but suppress their output for the distribution binary.

You can remove your NSLog statements using sed and grep. The basic idea is to grep all lines containing NSLog statements and then delete them using sed.

Using sed and grep might be new to you, but it's very helpful in the long run!

Here's some code I think should work, but backup your work first: grep -Ev 'NSLog'.

Dear @ryyst, I would not appreciate a technique that is irreversible & backup dependent.
