Correct place to define Constants?

Question

where is the right place to define contants in an Xcode project? Such as an URL, that wont change or some images for a different backgroundstyle. AppDelegate.h? If so, where exactly? I'd like to create clean code.

Thanks

Which programming language are you using? The "clean" version will vary slightly from language to language. — Jared, Mar 05 '14 at 20:58
Hello, sorry, I thought the Xcode-Keyword will do. Its Objective-C. — Philip, Mar 05 '14 at 21:11

What about you create a header file, probably constants.h and define your constants in it, for example

#define URL_WEBSERVICE @"http://..."
#define COLOR_TEXT [UIColor colorWithRed:.75 green:1.0 blue:.4 alpha:1.0]
#define MAX_RESULTS 100

You can also import this header file into your precompiled header file .pch so that the values in it become visible to all your files.

If these constants are to be globally visible then this is a perfectly fine solution. If they are specific to a source file, then they should probably just be defined at the top of the source file. If you want them to be visible to any code using a class, then they should be defined in the header file for the class. – Jared Mar 05 '14 at 21:26
I like this way of fixing the problem. Very clean! Thanks! I voted. – Philip Mar 06 '14 at 00:14
