create a viewcontroller for each view screen?

Do you create a Viewcontroller per view screen? or should you share a viewcontrollers? (ie in the example below Should there be 3 controllers or just 1 controller?)

Example Screens are related

Screen1 (input information), 
Screen2 (Review and confirm Information), 
Screen3 (thank you / status response).

In your case you definitely don't need separate controllers. In fact you don't even need separate views. You can create a single view to take information, process it in the same controller and show the result in a UIAlertView.

You should code according to the MVC paradigm. Parcel out your code and separate it based on overrarching function. Here is a high level overview of MVC

(Data) Model: contains all of your app data, objects that are passed around and used to populate the views

View: everything that is some sort of visual output

Controller: Classes that make the models and views work together.

What this is saying, in iPhone development parlance, is don't just jam a bunch of code into your UIViewController subclass. If you want to change the way part of the system works, having one huge class with a ton of code in it is a lot harder to edit and fix, than several smaller classes with a specialized use.

To answer your question, you should most definitely use one controller for each view function, but going beyond that, you should create specialized classes that take the inputs and manipulate that data, create specialized classes that then use the data to send it back to the user in an output.

Don't put all of your code into one class. It might work, but if you ever need to tweak it, or, just like when the iPad came out, it has to be adapted to use on another platform, it will be easier to manage if you only have to change something small to make it work
