Cocoa Design Patterns

Unlocking the Secrets of Cocoa and Its Object-Oriented Frameworks

 

Mac and iPhone developers are often overwhelmed by the breadth and sophistication of the Cocoa frameworks. Although Cocoa is indeed huge, once you understand the object-oriented patterns it uses, you’ll find it remarkably elegant, consistent, and simple.

 

Cocoa Design Patterns begins with the mother of all patterns: the Model-View-Controller (MVC) pattern, which is central to all Mac and iPhone development. Encouraged, and in some cases enforced by Apple’s tools, it’s important to have a firm grasp of MVC right from the start.

 

The book’s midsection is a catalog of the essential design patterns you’ll encounter in Cocoa, including

• Fundamental patterns, such as enumerators, accessors, and two-stage creation
• Patterns that empower, such as singleton, delegates, and the responder chain
• Patterns that hide complexity, including bundles, class clusters, proxies and forwarding, and controllers

And that’s not all of them! Cocoa Design Patterns painstakingly isolates 28 design patterns, accompanied with real-world examples and sample code you can apply to your applications today. The book wraps up with coverage of Core Data models, AppKit views, and a chapter on Bindings and Controllers.

 

Cocoa Design Patterns clearly defines the problems each pattern solves with a foundation in Objective-C and the Cocoa frameworks and can be used by any Mac or iPhone developer.

Buck founded EMB & Associates, Inc. in 1993 and built the company into a leader in the aerospace and entertainment software industries by leveraging the NeXT/Apple software technology that would later become Apple&;s Cocoa frameworks. Mr. Buck has also worked in construction, taught science to 8th graders, exhibited oil on canvas portraits, and developed alternative fuel vehicles. Mr. Buck sold his company in 2002 and currently holds the title of Senior Staff at Northrop Grumman Corporation. Mr. Buck received a B.S. degree in computer science from the University of Dayton in 1991 and is a frequent contributor to Cocoa mailing lists and technical forums.

 

Donald A. Yacktman has been using Cocoa and its predecessor technologies, OpenStep and NextStep, professionally since 1991. He coauthored the book Cocoa Programming and has contributed to the Stepwise website as both author and editor. He has worked for Verio/iServer and illumineX in the past. At present he works as an independent consultant assisting in the design and implementation of Cocoa and iPhone applications. Mr.Yacktman received B.S. and M.S. degrees in electrical and computer engineering from Brigham Young University in 1991 and 1994, respectively.
