Chapter 6: How Do I Use Objects in My Code?

Objective-C is very different from C. The code looks similar, and many apps combine elements of both languages. But using Objective-C makes you think about the design of your app in a more abstract way that is less tied to computer hardware. Objective-C is a much looser language than C, and you can use its features to change how your app responds to events as it runs. With Objective-C, the goal isn’t just code that works; the goal is intelligent code with a wide range of possible behaviors. You can use Objective-C to create simple, linear code, but its powerful features can help you add smarts to your apps.
