Where To Go From Here?
You can download a copy of the project up to this point.
You've set up a base Vehicle class with Car, Motorcycle, and Truck subclasses, all listed in the same table view. However, there’s no way to verify that all of your truck's size-specific handling is working correctly.
Part 2 of this tutorial will fill out the rest of the app to display more vehicle details. Along the way, you'll learn about polymorphism and a couple of additional major design patterns for Object-Oriented Programming.
Until then, why not try implementing a Bicycle class or a few more custom properties to some of the vehicle subclasses? Or you can read up on Apple's reference guide Object-Oriented Programming with Objective-C.
