I've written a framework which I use in several applications. This

framework has a MyFramework_Prefix.pch in which I define macros and other

Prefix Header Build Setting set to MyFramework_Prefix.pch.

Now, I have a need to #define a compile-time variable in ONE project only.

I cannot do it in the source code files, because these files are used in

multiple projects. I cannot do it in MyFramework_Prefix.pch, because it is

the Prefix Header for all my projects. Where can I put this #define?

(I tried three guesses at a syntax in a .pch file which would allow me to

"include" other .pch files, but none of them worked.)

Try in the target's Preprocessor Definitions build setting. Make sure to set it for all configurations of the target where you want it set. The fomat is FOO=1 (space-separated list).

If your targets or projects share precompiled headers, and this macro doesn't affect them, set it in Preprocessor Definitions Not Used in Precompiled Headers, so that it won't spin a new set of precompiled headers just for the target that has the macro defined.
