Answer 1

As an addendum, if you are using this technique to define strings in your target, this is how I had to define and use them:

In Build Settings -> Preprocessor Macros, and yes backslashes are critical in the definition:

APPURL_NSString=\@\"www.foobar.org\"

And in the source code:

objectManager.client.baseURL = APPURL_NSString;

Answer 2

You can duplicate the target which has the preprocessing section, rename it to any name you want, and then change your Preprocessor macro value.
