"Cocoa Programming: A Quick-Start Guide for Developers" shows you how to get productive with Cocoa-fast We won't walk you through every class and method in the API (but we will show you where to find that information). Instead, we'll jump right in and start building a web browser using Cocoa. In just a few minutes you'll have something that works. A couple of minutes more, and you'll have code in your custom controller, listening for notifications and call-backs. Soon you'll have the functionality you'd expect in a full browser. And that's just the first few chapters.
