Learning the iOS 4 SDK for JavaScript Programmers

Recap

In this chapter you have probed deeper into Objective-C classes and received an overview of the most common Cocoa Touch classes that will handle your code’s data. When you first encounter the class reference documents for classes such as NSString, NSArray, and NSDictionary, their idiosyncratic complexity may overwhelm you. It’s more important at this stage of your learning to gain a solid grounding on the basics presented here, which should get you to the equivalent point of your knowledge of the JavaScript analogues. In time, you’ll discover operations you can perform with these basic data objects in iOS that you only dreamt of in the JavaScript world. Despite the learning curve, you will eventually feel liberated.

To assist further in making the transition from JavaScript to Objective-C and iOS frameworks classes, the next chapter offers what amounts to recipes in the new environment for tasks you likely perform in JavaScript. Sometimes the analogues are clear, but not always. Where necessary, I will try to guide you to the new ways you have to approach tasks for your iOS apps.
