I was reading on a couple blogs about setting 'Other C Flags' to
-DTARGET_NAME=${TARGET_NAME} so that I can have multiple targets and
differentiate between them in my code. But when I try to access it in my
code it keeps treating the value of TARGET_NAME as a variable.


In other words, if TARGET_NAME = "FullVersion", and I try to check it:

NSString *version = [NSString stringWithFormat:@"%@", TARGET_NAME];

I get the error: 'FullVersion' undeclared (first use in this function)

How can I access it and treat it as a string???

Try one of these:

1. Add quotes to your -D. The actual syntax depends on your shell / build environment; you need to protect the quotes from everyone except the compiler itself. Try something like this:
-DTARGET_NAME=\"${TARGET_NAME}\"


2. Use the # operator to turn your unquoted identifier into a string:
    #define STRING(x) #x
    [NSString stringWithFormat:@"%s", STRING(TARGET_NAME)]

Note that both of these turn TARGET_NAME into a C string, so you'd need to use %s instead of %@. Producing a @"" string or CFSTR() string is left as an exercise for the reader.
