The UIViewController TDD screencast ended with all the code in the view controller. Unfortunately, this is where many iOS programmers leave things! Let’s TDD our way to something better…
In part 2, we pick up from there and TDD to extract a model class, which the controller observes. You’ll see it evolve into true Model-View-Controller, driven by unit tests.
In particular, you’ll see how to TDD:
- a model that posts notifications when it changes, and
- a controller that observes those notifications.
