iOS 5 Programming Cookbook: Solutions & Examples for iPhone, iPad, & iPod Apps – #bookreview

iOS 5 Programming Cookbook
By Vandad Nahavandipoor
(O’Reilly, paperback, list price $49.99; Kindle edition, list price $39.99)

This huge and helpful “cookbook” does not ignore iOS novice programmers. But the author, a veteran software developer, expects readers to at least be “comfortable with the iOS development environment and know how to create an app for the iPhone or iPad.”

His well-structured new edition “presents useful ways to get things done” and promises that readers “will learn a lot more about the basics of iOS programming, and a lot more about UIKit, dictionaries, arrays, loops, and conditionals.”

He notes that “[a] lot has changed in iPhone, iPad, and iPod touch programming since the introduction of iOS 5. The whole runtime and the way we write Objective-C code has dramatically changed. ARC (Automatic Reference Counting) is now introduced into the LLVM Compiler, which in some ways gives us more flexibility and in other ways makes the runtime more fragile.”

Nahavandipoor’s 852-page book is loaded with code examples, screenshots, and other illustrations and is divided into 17 chapters and an index.

  • Chapter 1: The Basics - An overview of  Objective-C.
  • Chapter 2: Implementing Controllers and Views - “Describes various approaches to constructing your iOS application’s user interface…”
  • Chapter 3: Constructing and Using Table Views - Shows how to use table views “to create professional-looking iOS applications.”
  • Chapter 4: Storyboards - The process of storyboarding can help you “define the connections between different screens in your app.” And, with storyboarding, “you don’t have to know anything about iOS programming to get a simple app running.”
  • Chapter 5: Concurrency - Focuses on Grand Central Dispatch, “Apple’s preferred way of achieving concurrency in iOS.” Also looks at timers, threads, and operations.
  • Chapter 6: Core Location and Maps - Describes “how you should use Map Kit and Core Location APIs to develop location-aware iOS applications.”
  • Chapter 7: Implementing Gesture Recognizers - Shows “how to use all available gesture recognizers in the iOS SDK, with working examples tested on iOS 5 on different devices such as the iPhone 3GS, iPhone 4, and iPad.”
  • Chapter 8: Networking, JSON, XML, and Twitter - Includes downloading data from a URL and parsing XML files. The pros and cons of synchronous and asynchronous connections. Caching files in memory and on disk to minimize an iOS device’s bandwidth consumption.
  • Chapter 9: Audio and Video - Focuses on “the AV Foundation and Media Player frameworks that are available on the iOS SDK.”
  • Chapter 10: Address Book – Structured to help Objective-C developers get a handle on the Address Book framework and how to retrieve contacts, groups, and their information. “The Address Book framework is composed entirely of C APIs.” So, “many Objective-C developers find it difficult to use this framework….”
  • Chapter 11: Camera and the Photo Library - Shows how to “determine the availability of front- and back-facing cameras on an iOS device.” Also looks at accessing the Photo Library “using the Assets Library framework…available in iOS 4 and later” and editing videos on an iOS device.
  • Chapter 12: Multitasking - Explains and presents examples that show “how to create multitasking-aware aplications that run beautifully on iOS 4 and above.”
  • Chapter 13: Core Data - Using Core Data to “maintain persistent storage for your iOS applications….”
  • Chapter 14: Dates, Calendars, and Events - Shows how to use “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.”
  • Chapter 15: Graphics and Animations – Introduces the reader to the Core Graphics framework and shows how to work with images and text and graphics context.
  • Chapter 16: Core Motion - Introduces the Core Motion framework and shows how to access the accelerometer and gyroscope on an iOS device. (Not all devices have those capabilities.)
  • Chapter 17: iCloud - “Shows how to use the iCloud service, which ties devices together and allows them to share data…as the user moves from one device to another.”

More than 100 new recipes have been added to this updated second edition of Nahavandipoor’s book. He also provides extensive references and links to other materials, including some Apple documents that he believes “every professional iOS developer should read.”
