Make Better Things

This is very good optimization if you remove all your NSLog statement from project. But its hard to find every NSLog and remove it if you have a big project. Well here are two tips -

1) Use ifndef to replace NSLog with blank. Here is an example -

#ifndef __OPTIMIZE__
#define NSLog(...) NSLog(__VA_ARGS__)
#else
#define NSLog(...) {}
#endif

2) User regular expression in Find and replace to remove NSLogs

a) Press command + shift + f to open find and replace in whole project.
b) Search for

NSLog.*;

and replace it with blank
