Do I need to disable NSLog before release Application?

I wonder if someone could help me setup a number of NSLog statements so they print to console when executing in “Debug Mode” but don’t print in “Release Mode”. I understand I need to add something like DEBUG = 1 to the debug config in Xcode but I can’t find where. Also how do I utilise this in my code?

NSLog(@"Print Always");
if(DEBUG) NSLog(@"Print only in debug");

Is there a simple way of doing this?

EDIT_001:
I tried following this but the keys now seem to be only listed under “All Settings”, and are presenting as nice names. The one I should be using is GCC_PREPROCESSOR_DEFINITIONS, so I needed to find “Preprocessor Macros”, select edit and add DEBUG=1

When you come to use this its simply a case of adding (see below) or some marco to remove the messy #ifdef / #endif tags.

NSLog(@"You always see me?");
#ifdef DEBUG
NSLog(@"Only in DEBUG");
#endif

See comments about using either -DDEBUG=1 or DEBUG=1.
