Is it possible for JavaScript programmers to learn Apple's iOS 4 SDK and live to tell the tale? Technology guru Danny Goodman did, and with this book he leaves a well-marked trail for you to follow. An authority on JavaScript since its inception, Goodman understands the challenges you might face in creating native iOS apps with this SDK, and introduces Xcode, Objective-C, and Cocoa Touch in a context you'll readily understand. Why bother with the SDK when you can simply build web apps for Apple's iOS devices? Web apps can't access an iPhone's music library, camera, or iOS system software for maps, audio, and more. Nor can you sell web apps in the App Store. If you want to take full advantage of the iPhone and iPad, iOS 4 SDK is your tool -- and this is your book. Includes full coverage of iOS SDK 4.2. Learn the distinction between web app and iOS native app programming Create a workbench app to test code snippets throughout the learning process Get a structural view of an iOS app, and compare the process of building objects in Objective-C versus JavaScipt Discover how your code launches iOS apps and makes them user-ready Learn about iOS memory management details that are different from JavaScript, including pointers and data types Use Objective-C and Cocoa Touch to implement common JavaScript tasks

With this revised and expanded edition, you'll dig into Cocoa and learn how to work effectively with Objective-C and Xcode. This book covers iOS 6 in a rigorous, orderly fashion--ideal whether you're approaching iOS for the first time or need a reference to bolster existing skills. Learn about features introduced with iOS 6, including Objective-C language advances, autosynthesis, autolayout, new view controller rotation rules, unwind segues, state restoration, styled text, and collection views. Learn Objective-C language details and object-oriented programming concepts Understand the anatomy of an Xcode project and all the stages of its lifecycle Grasp key Cocoa concepts such as relationships between classes, receiving events, and model-view-controller architecture Learn how views and layers are managed, drawn, composited, and animated Become familiar with view controllers and their relationships, along with nib and storyboard management Fully explore all basic interface objects such as scroll views, table views, and controls Delve into Cocoa frameworks for sound, video, sensors, maps, and other features Touch on advanced topics such as threading and networking

Most programming languages contain good and bad parts, but JavaScript has more than its share of the bad, having been developed and released in a hurry before it could be refined. This authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole—a subset you can use to create truly extensible and efficient code. Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of good ideas that make JavaScript an outstanding object-oriented programming language-ideas such as functions, loose typing, dynamic objects, and an expressive object literal notation. Unfortunately, these good ideas are mixed in with bad and downright awful ideas, like a programming model based on global variables. When Java applets failed, JavaScript became the language of the Web by default, making its popularity almost completely independent of its qualities as a programming language. In JavaScript: The Good Parts, Crockford finally digs through the steaming pile of good intentions and blunders to give you a detailed look at all the genuinely elegant parts of JavaScript, including: Syntax Objects Functions Inheritance Arrays Regular expressions Methods Style Beautiful features The real beauty? As you move ahead with the subset of JavaScript that this book presents, you'll also sidestep the need to unlearn all the bad parts. Of course, if you want to find out more about the bad parts and how to use them badly, simply consult any other JavaScript book. With JavaScript: The Good Parts, you'll discover a beautiful, elegant, lightweight and highly expressive language that lets you create effective code, whether you're managing object libraries or just trying to get Ajax to run fast. If you develop sites or applications for the Web, this book is an absolute must.
