iOS SDK Development
Chris Adamson and Bill Dudney
(Pragmatic Bookshelf, paperback)
The previous, 2009 edition of this popular how-to book was titled iPhone SDK Development. But this new and re-titled second edition is much more than a copy-and-paste, just-make-some-tweaks update.
“[W]e have copied absolutely nothing from the old book,” the authors say. “As we looked at all the changes to the platform—between Xcode 4, iOS 6, and the iPad—we decided that so much had changed that we would be better off starting fresh.”
While they tried to cover virtually everything in their previous book, their new, 274-page edition is much more focused and, yes, it’s more pragmatic.
“This book,” they state, “is about setting you off on the right foot: understanding the fundamentals, getting comfortable with the tools and the concepts, and developing good habits. We’ve put a particular emphasis on the last of these, looking for the kinds of things that aren’t just handy classes or compiler tricks but instead are the values and routines that will help produce better apps. We’re also adopting modern iOS development practices, such as using Objective-C properties exclusively instead of using traditional instance variables and getting private methods out of public header files.”
Two other goals: They want iOS SDK Development “to serve as a prerequisite” for Pragmatic Bookshelf’s other iOS titles; and they hope you will “come away from this book with a firm grasp of the most essential iOS APIs—the UIKit GUI framework and the essential utilities of the Foundation framework—and enough of a sense of where things are and how things work to be able to grab the documentation for interesting looking features and be able to figure it out.”
The book has 10 chapters, with illustrations and short code examples. The chapters are:
- Tweetings and Welcome to iOS 6 – Shows how to download and install the SDK and begin working on a first app.
- Programming for iOS –Introduces Objective-C and “the two frameworks we use most often in iOS apps: Foundation and UIKit.”
- Asynchronicity and Concurrency – Shows “how many of the iOS APIs use asynchronous callbacks and [employ] the Grand Central Dispatch system to handle concurrent execution….”
- View Controllers – “…looks at how iOS apps are built on a strong Model-View-Controller (MVC) foundation.”
- Table Views – Deals with “the flexible and widely used table view, the linchpin of most iPhone apps that need to present lists of data.
- Storyboards and Container Controllers – Covers “how to build a visual road map of the many screens of an app and how to build much of the logic of that navigation and presentation automatically.”
- Documents and iCloud – Shows the tools needed “to save our user’s work to the filesystem as well as to Apple’s new iCloud service.”
- Drawing and Animating – Explains how to use the Core Graphics framework and Core Animation.
- Testing and Fixing Apps – Looks at what can go wrong and how to use the SDK’s tools to fix things.
- The App Store and Beyond – Focuses on moving from learning to doing, by maintaining code, running it on devices, submitting it on the App Store, and “managing it after it’s in users’ hands.”
Whether you want to learn how to develop iPhone, iPad, and iPod Touch apps, or improve and update your knowledge of the necessary processes, you should read the new, improved iOS SDK Development and keep it within easy reach.
