But hey, I'm not proud. Or tired.
I'm passing a name-and-value into my code via the build process, thru the
preprocessor macros build setting. All well and good; using #ifdef and
logging I can tell that the #define of the *name* is working. My question
is: can my *code* capture the *value* as an NSString? (And if so, how?) Thx

PS Or feel free to tell me that there's a better way for the build process
to send messages to my code.
You have to use token pasting to concatenate the double quotes to the macro expansion.
#define QUOTE "
#ifdef MACROVALUE NSLog("%@", @QUOTE##MACROVALUE##QUOTE);
(Off the top of my head; code not compiled)
