where to store constants in an iphone app?

Question

Where do you store app configurations constants (not user preferences)?

• store in Info.plist?
• store in SomeOther.plist?
• store as static (extern?) constant in a .h?
• store as #define somewhere? (where?)

Thanks.

Answer 1

I store instance constants as a static in implementation class. Never had a global constant but I guess I would place it in the App delegate.

Answer 2

If they don't have to be preserved after the application is being closed AppDelegate is fine. if they have to, then use NSUserDefaults class ;)

Answer 3

Save them in NSUserDefaults. Here is a good example:

Answer 4

I do it in a very oldskool C way. I have just a file like Constants.h where I go

#define SOMETHING value

And then I just #include "Constants.h" in my code and use SOMETHING.
