Create a wizard set of screens on the iPad

Question

I want to create a managed “Wizard” set of screens on an iPad. So there is one main screen with N sub-steps in it that go through. You should be able to go back and forth in steps, but also have a Home button that goes to the base step.

So the technical problem is this: how does the screen unload and load another screen that is next in sequence?

Answer 1

I highly recommend that you use a UINavigationController (perhaps like a ModalViewController), as it is designed to be used this way with a chain of subview controllers for each configuration step. Share one object on all view controllers to track user and voila progress!

You can use one UIViewController with various full-screen displays that are shown / hidden, but I really see no reason to do it this way: the UINavigationController will also feel familiar to your users where this might be a non-standard solution.
