I have an Xcode project which has lots of NSLog statementS.

I have to submit my app to get approval from Apple, and I would like to remove all NSLog statementS which I had used for debugging.

I want to remove only NSLog statements.

but if we use the regular expression in xcode find & replace by selecting regular expression textbox in that,we can select all the NSlog statements.but i want to know that how to specify regular expression for NSLog(...);. — Vijay-Apple-Dev.blogspot.com, Apr 02 '11 at 08:47

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. – Josh Peak Jul 31 '12 at 22:12

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. – Abhishek Bedi Apr 23 '13 at 05:30
