iOS 5 Programming Cookbook

Organization of This Book

In this book, we will discuss frameworks and classes that are available in iOS 3 and iOS 4. In some recipes, you will find code that runs only on iOS 4 and later; in those recipes, I note that you will need the iOS 4 SDK or later to compile the example code.

Here is a concise breakdown of the material each chapter covers:

Chapter 1, The Basics

Explains how Objective-C classes are structured and how objects can be instantiated. The chapter talks about properties and delegates as well as memory management in Objective-C. Even if you are competent in Objective-C, I strongly suggest that you go through this chapter, even if you are skimming through it, to understand the basic material that is used in the rest of the chapters.

Chapter 2, Implementing Controllers and Views

Describes various approaches to constructing your iOS application’s user interface by taking advantage of different tools the SDK provides. This chapter also introduces you to features that are only available on the iPad, such as the popover and split view controllers.

Chapter 3, Constructing and Using Table Views

Shows how you can work with table views to create professional-looking iOS applications. Table views are very dynamic in nature, and as a result, programmers sometimes have difficulty understanding how they should work with them. By reading this chapter and having a look at and trying out the example code, you will gain the knowledge that is required to comfortably work with table views. ...
