How to use global variables in Objective-C?

Question

How should I declare a global variable in my Objective-C project?

Answer 1

Globals rock! I don't know what everyone is scared of. I used them successfully here.

Passing Data between View Controllers

Also used UIStepper to adjust values in another viewController. I could see them being an issue is larger programs, and in my opinion the singleton thing is just a masked global. Keep it simple, if your app is simple that is.
