The Appendix includes a compendium of miscellaneous code examples for cool application features, such as using the camera and creating a CoverFlow®-like album browser.
This book is a true hacker's book, designed for the millions of users who have run third party applications on their iPhone, but its concepts and code examples have shown to be remarkably similar to Apple's official SDK, making this book a valuable resource for both camps. Any programmer can use this book to write applications with the same spectacular effects that made the device an immediate hit, and impress users just as much as the official iPhone software does. That programmer can easily be you.
