.　　Demonstrates how to download data from a URL and parse XML files. You will learn about synchronous and asynchronous connections and their pros and cons.You will also learn about caching files in memory and on disk to avoid consuming the possibly limited bandwidth of an iO$ device on which your application could be running.
　　Chapter 7, Operations, Threads, and Timers
　　Provides details regarding operations, threads, and timers. Using the material in this chapter, you can develop modern multithreaded iOS applications. In addition, you will learn about operations and operation queues, and how to avoid implementing your own threads and instead let iOS do it for you.
　　Chapter 8, Audio and Video
　　Discusses the AV Foundation and Media Player frameworks that are available on the lOS SDK. You will learn how to play audio and video files and how to handle interruptions, such as a phone call, while the audio or video is being played on both lOS 3 and iOS 4. This chapter also explains how to record audio using an iOS device's built-in microphone(s). At the end of the chapter, you will learn how to access the iPod Library and play its media content, all from inside your application.
　　Chapter 9, Address Book
　　Explains the Address Book framework and how to retrieve contacts, groups, and their information from the Address Book database on an iOS device. The Address Book framework is composed entirely of C APIs. Because of this, many ObjectiveC developers find it difficult to use this framework compared to frameworks that provide an Objective-C interface. After reading this chapter and trying the examples for yourself, you will feel much more confident using the Address Book framework.
　　Chapter 10, Camera and the Photo Library
　　Demonstrates how you can determine the availability of front- and back-facing cameras on an iOS device. Some of the recipes in this chapter are specific to iOS 4, with the rest working on both iOS 3 and iOS 4. You will also learn how to access the Photo Library using the Assets Library framework which is available in iOS 4 and later. At the end of the chapter, you will learn about editing videos right on an iOS device using a built-in view controller.
　　Chapter 11, Multitasking
　　Explains, with examples, how to create multitasking-aware applications that run beautifully on lOS 4. You will learn about background processing, from playing audio and retrieving users' locations in the background, to downloading content from a URL while your application is running in the background.
　　Chapter 12, Core Data
　　Describes how to maintain persistent storage for your iOS applications using Core Data. You will learn how to add to, delete from, and edit Core Data objects and how to boost access to data in a table view. In addition, you will learn how to manage relationships between Core Data objects.
　　Chapter 13, Event Kit
　　Demonstrates the use of the Event Kit and Event Kit UI frameworks, which are available on iOS 4 and later, in order to manage calendars and events on an iOS device. You will see how to create, modify, save, and delete events. You will also learn, through examples, how to add alarms to calendar events and how to set up CalDAV calendars so that you can share a single calendar among multiple devices.
　　Chapter 14, Graphics
　　Introduces the Core Graphics framework. You will learn how to draw images and text on a graphics context, grab the contents of a graphics context and save it as an image, and much more.
　　Chapter 15, Core Motion
　　Explains the Core Motion framework, which is new in iOS 4. Using Core Motion, you will access the accelerometer and the gyroscope on an iOS device. You will also learn how to detect shakes on a device. Of course, not all iOS devices are equipped with an accelerometer and a gyroscope, so you will also learn how to detect the availability of the required hardware.
　　Additional Resources
　　From time to time, I refer to official Apple documentation. Some of Apple's descriptions are right on the mark, and there is no point in trying to restate them. Throughout this book, I have listed the most important documents and guides in the official Apple documentation that every professional iOS developer should read.
　　For starters, I suggest that you have a look at the "iPhone Human Interface Guidelines" and the "iPad Human Interface Guidelines." These two documents will tell you everything you should know about developing engaging and intuitive user interfaces for the iPhone/iPod and the iPad. Every lOS programmer must read these documents. In fact, I believe these documents must be read by the product design and development teams of any company that develops iOS applications.
