Enabling the macro value "DEBUG"

Question

In my code, I want to conditionally perform several operations with:

#ifdef DEBUG
NSLog(@"I'm in debug mode");
#endif

I configured Project-> Edit Project Settings-> Build tab so that "DEBUG" is specified as a user parameter with a value of 1. Debug is selected in the "Configuration" drop-down list. This still does not include the Debug build directive, although I thought it would.

What else do I need to do at the build stage to resolve this?

Answer 1

To do this, you need to set the compiler flag.

, , , Debug ( ) C ++ ( Xcode 3.1 GCC 4.2 - ).

: -DDEBUG .

DEBUG , .

Answer 2

project → settings → c/++ ( ?) DEBUG , .

Answer 3

SDK 3.0, 2.2.1 XCode 3.1.
