THE #1 BESTSELLING BOOK ON OBJECTIVE-C 2.0 Programming in Objective-C 2.0 provides the new programmer a complete, step-by-step introduction to Objective-C, the primary language used to develop applications for the iPhone, iPad, and Mac OS X platforms. The book does not assume previous experience with either C or object-oriented programming languages, and it includes many detailed, practical examples of how to put Objective-C to use in your everyday iPhone/iPad or Mac OS X programming tasks. A powerful yet simple object-oriented programming language that’s based on the C programming language, Objective-C is widely available not only on OS X and the iPhone/iPad platform but across many operating systems that support the gcc compiler, including Linux, Unix, and Windows systems. The second edition of this book thoroughly covers the latest version of the language, Objective-C 2.0. And it shows not only how to take advantage of the Foundation framework’s rich built-in library of classes but also how to use the iPhone SDK to develop programs designed for the iPhone/iPad platform.

Write Truly Great iOS and OS X Code with Objective-C 2.0! Effective Objective-C 2.0 will help you harness all of Objective-C’s expressive power to write OS X or iOS code that works superbly well in production environments. Using the concise, scenario-driven style pioneered in Scott Meyers’ best-selling Effective C++, Matt Galloway brings together 52 Objective-C best practices, tips, shortcuts, and realistic code examples that are available nowhere else. Through real-world examples, Galloway uncovers little-known Objective-C quirks, pitfalls, and intricacies that powerfully impact code behavior and performance. You’ll learn how to choose the most efficient and effective way to accomplish key tasks when multiple options exist, and how to write code that’s easier to understand, maintain, and improve. Galloway goes far beyond the core language, helping you integrate and leverage key Foundation framework classes and modern system libraries, such as Grand Central Dispatch. Coverage includes Optimizing interactions and relationships between Objective-C objects Mastering interface and API design: writing classes that feel “right at home” Using protocols and categories to write maintainable, bug-resistant code Avoiding memory leaks that can still occur even with Automatic Reference Counting (ARC) Writing modular, powerful code with Blocks and Grand Central Dispatch Leveraging differences between Objective-C protocols and multiple inheritance in other languages Improving code by more effectively using arrays, dictionaries, and sets Uncovering surprising power in the Cocoa and Cocoa Touch frameworks

Get Started Fast with Objective-C 2.0 Programming for OS X, iPhone, iPod touch, and iPad If you want to learn Objective-C 2.0 to write programs for Mac OS X, iPhone, iPad, or iPod touch, you’ve come to the right place! Concise, readable, and friendly, Learning Objective-C 2.0 is the perfect beginner’s guide to the latest version of Objective-C. Longtime Mac OS X and iPhone developer Robert Clair covers everything from the absolute basics to Objective-C 2.0’s newest innovations. Clair begins with a practical refresher on C and object-oriented programming and walks you through creating your first Objective-C program with Xcode. Next, you’ll master each core language feature, from objects and classes to messaging, frameworks, and protocols. Every concept is illustrated with simple examples, and many chapters contain hands-on practice exercises. Throughout, Learning Objective-C 2.0 focuses on the features, concepts, and techniques that matter most day to day. The result is an outstanding first book for everyone who wants to begin programming for iPhone, iPod touch, iPad, or Mac OS X. COVERAGE INCLUDES Understanding methods, messages, and the Objective-C messaging system Defining classes, creating object instances, and using class objects Using categories to extend classes without subclassing Simplifying development with Objective-C 2.0 declared properties Using protocols to emphasize behavior rather than class Working with common Foundation classes for strings, arrays, dictionaries, sets, and number objects Using Objective-C control structures, including Objective-C 2.0’s new fast enumeration construct Understanding application security and hiding the declaration of methods that should stay private Using the new blocks feature provided in Objective-C 2.0

Get Started Fast with Objective-C 2.0 Programming for OS X Mountain Lion, iOS 5.1, and Beyond Fully updated for Xcode 4.4, Learning Objective-C 2.0, Second Edition, is today’s most useful beginner’s guide to Objective-C 2.0. One step at a time, it will help you master the newest version of Objective-C 2.0 and start writing high-quality programs for OS X 10.8 Mountain Lion, iOS 5.1, and all of Apple’s newest computers and devices. Top OS X and iOS developer Robert Clair first reviews the essential object and C concepts that every Objective-C 2.0 developer needs to know. Next, he introduces the basics of the Objective-C 2.0 language itself, walking through code examples one line at a time and explaining what’s happening behind the scenes. This revised edition thoroughly introduces Apple’s new Automated Reference Counting (ARC), while also teaching conventional memory-management techniques that remain indispensable. Carefully building on what you’ve already learned, Clair progresses to increasingly sophisticated techniques in areas ranging from frameworks to security. Every topic has been carefully chosen for its value in real-world, day-to-day programming, and many topics are supported by hands-on practice exercises.
