How to delete all NSLog’s & comments from the Xcode application

deletinglogsxcode

Is there anyway to delete the NSLog lines from the app by any trick/tool? I usually use NSLog's in each & every method to understand the flow of control & to know about the values of the app's variables. I also use lots of commend lines to explain the nature of methods and variables.

But, in some stage, these NSLog's & comment lines confusing the program understanding (It's to me). So I need to again & again deleting/creating this logs & comments. Is there a way to show/hide them by any trick in Xcode?

Thanks in advance

as a Dev, I can offer these two methods, although I agree with Daniel, that Stack Overflow is a better place to ask this.

Anyway, the first is a simple replace.

Shift-Option-f. Then type NSLog. That will find all the occurances of NSLog in your app.

Then switch find to replace. Then replace "NSLog" with "//NSLog". That will comment out all of them.

A second - better option takes a bit more work.

First, do the above but instead of replacing the string with "//NSLog", replace it with something like "DLog".

Then, in the prefix.pch file.. Write something like this:

#ifdef DEBUG
#    define DLog(...) NSLog(__VA_ARGS__)
#else
#    define DLog(...) 
#endif
#define ALog(...) NSLog(__VA_ARGS__)

This way, while your app is in debug mode, all the logs will appear, but when you move your app to release mode, the logs are hidden.

Hope this helps.
