• Learn the native programming language for Mac OS X,

as well as the iPhone!

• Get up and running quickly with Objective-C We don’t waste time teaching you basic programming; instead, we focus on what

makes Objective-C different and cool.

• Learn about sophisticated programming concepts, including object-oriented programming, the Open-Closed Principle,

refactoring, key-value coding, and predicates.

In this book, you’ll find a full exploration of the Objective-C programming

language, the primary language for creating Mac OS X and iPhone applica-tions There are goodies here for everyone, whether you’re just starting out as

a Mac developer or a grizzled programmer coming from another language

You’ll discover all of the object-oriented purity and Smalltalk heritage coolness

of Objective-C—such as instantiation, protocols for multiple inheritance, dynamic typing, and message forwarding Along the way, you’ll meet Xcode, the Mac

development environment, and you’ll learn about Apple’s Cocoa toolkit

Nearly everyone wants to be able to develop for Mac OS X or the iPhone these days, and it’s no wonder The Mac is a fun and powerful platform, and Objective-C

is a wonderful language for writing code You can have a great time programming the Mac in Objective-C We do, and want you to join us!

Mark Dalrymple is a longtime Mac and Unix programmer who has code running all over the world.

Scott Knaster is a legendary Mac programmer and author of more than
