iPhone #ifdef directive not working as expected

I am using Xcode 4 to update one of my apps that were previously developed with Xcode 3.

On one part of the code I had:

#define CREATE YES

and later...

#ifdef CREATE
// do stuff
#endif

on Xcode 3, this branch would be executed just if CREATE was yes but now in Xcode 4 it is being executed all the time.

As far as I see that Xcode 4 approach appears to be the most correct, as I am asking if the variable is defined, Xcode 3 worked somehow as I wanted.

So, now, how do I test for the boolean value of CREATE on Xcode 4?

something like:

#ifdef CREATE == YES
// DO STUFF
#endif

thanks.

#define CREATE 1
#if CREATE
// do stuff
#else
//do other stuff
#endif

i think that's what you're looking for?

try using the #if directive instead of #ifdef

#define CREATE NO

#if CREATE
//This should not run.
#endif
