| Certain technologies bring out everyone's hidden geek, and
iPhone did the moment it was released. Even though Apple
created iPhone as a closed device, tens of thousands of
developers bought them with the express purpose of designing
and running third-party software.
In this clear and concise book, veteran hacker Jonathan
Zdziarski -- one of the original hackers of the iPhone --
explains the iPhone's native environment and how you can
build software for this device using its Objective-C, C, and
C++ development frameworks.
iPhone Open Application Development walks you through the
iPhone's native development environment, offers an overview
of the Objective-C language you'll use with it, and supplies
background for the iPhone operating system. You also get
detailed recipes and working examples for everyone's
favorite iPhone features -- graphics and audio programming,
interfaces for adding multitouch functionality to games, the
use of hardware sensors, and the device's vast user
interface kit.
This book explains:
How to access the iPhone's underlying operating system
The makeup of an iPhone application
How to get the open source tool chain running on your
desktop
The iPhone's core user interface framework, which is heavily
tied to major application-level functions
Using the many touted iPhone features such as multitouch,
hardware sensors, and gestures
Intercepting and handling event notifications for many
iPhone-related events
Raw video surfaces and 3D transformations that take you
deeper into advanced graphics on the iPhone
How to record and play simple sounds and intercept sound
events
Advanced digital audio output using Apple's new Audio
Toolbox framework
Advanced user interface components such as section lists,
keyboards, and image manipulation
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.
