Where to store global constants in an iOS application?

Question

Most of the models in my iOS app query a web server. I would like to have a configuration file storing the base URL of the server. It will look something like this:

Answer 1

The way I define global constants:

---

AppConstants.h

extern NSString* const kAppBaseURL;

AppConstants.m

#import "AppConstants.h"

#ifdef DEBUG
NSString* const kAppBaseURL = @"http://192.168.0.123/";
#else
NSString* const kAppBaseURL = @"http://website.com/";
#endif

---

Then in your {$APP}-Prefix.pch file:

#ifdef __OBJC__
  #import 
  #import 
  #import "AppConstants.h"
#endif

If you experience any problems, first make sure that you have the Precompile Prefix Header option set to NO.
