What really sets the iPhone
apart from laptops and PCs is its use of onboard sensors, including those that are location-enabled. This concise book takes experienced iPhone
developers on a detailed tour of iPhone
hardware by explaining how these sensors work, and what they're capable of doing.
With this book, you'll build sample applications for each sensor, and learn hands-on how to take advantage of the data each sensor produces. You'll gain valuable experience that you can immediately put to work inside your own iOS applications for the iPhone, iPod touch, and iPad.
