The first iOS developer's guide 100% focused on the iPhone/iPad's powerful sensors: accelerometer, magnetometer (compass), and gyroscope
* Concise, complete coverage of technologies that contribute powerfully to the iPhone/iPad's success, and are ignored in most iOS development books.
* Shows how to combine the sensors to create state-of-the-art apps, including games with 6-axis controllers.
* Packed with code examples reflecting the author's extensive experience developing sensor-based apps and games.
Using the iPhone's built-in sensors - accelerometer, magnetometer (compass), and gyroscope - you can create truly amazing apps. iOS sensors represent one of the most exciting ways to differentiate your apps from the competition, and are responsible for some of the App Store's hottest selling products. Now, for the first time, there's a complete guide to iOS sensor development with Apple's Core Motion framework. Programming iOS Sensors begins by explaining exactly what each of the sensors do, how they can replace and complement other user inputs, and what developers can do with the information they generate. After introducing each sensor's capabilities, the book dives directly into code - all of it practical, downloadable, designed for easy understanding and reuse, and fully explained. Readers won't just learn how to use sensors individually: they will learn how to combine them for even better results using CMDeviceMotion. For example, Programming iOS Sensors demonstrates how to create true six-axis game controllers for a richer, livelier gaming experience; how to take fuller advantage of sensors in GPS- and direction-based apps; and how to capture sensor information to create truly unique user experiences.
