iPhone Global Variable?

Question

I have two views with their own .h and .m files of course. How can I declare a bool (or any variable for that matter) in one view and be bale to access it in another view?

Answer 1

Create a data model class. Instantiate it in your app delegate, and pass it along to your view controllers. Use Key-Value Observing to track changes to the model in your view controllers. See my answer here: How do I display and calculate numbers from a database on iPhone?

"Why shouldn't I use globals? It can't hurt just this once." This is a bad habit to get into. Avoiding global variables makes your code easier to read and reuse, easier to extend, and easier to debug.
