A pre-release, “Rough Cuts” version of iPhone Open Application Development by Johnathan A. Zdziarski is now available from O’Reilly Media. Zdziarski is the developer of the first fully-functional application using the open iPhone toolkit, and most recently was responsible for explaining the situation regarding release of the iPhone 1.1.3 jailbreak update. According to O’Reilly’s web site, the book “explains in clear language how to create applications using Objective-C and the iPhone API, which in some ways resembles Apple’s desktop API and in some ways strikes new ground. After covering installation of the toolkits and some background about the operating system and Objective-C, the book offers detailed recipes and working examples for everyone’s favorite iPhone features. Graphics and audio programming, the CoreImage and CoreSurfaces interfaces for games programming, interfacing with iTunes, and the use of sensors are all covered.” Users who purchase the online Rough Cuts version can send suggestions, bug fixes, and comments directly to the author and editors, helping to shape the final release. The Rough Cuts version of the book is available from O’Reilly for $20 for an online-only copy. A pre-order of the print book runs $26, or users can purchase a bundle that offers both early online access and a final print copy for $44.
