Hour 20. Sensing the World

What You’ll Learn in This Hour:

The main difference between iPhones and standard computers is their portability and the number of sensors they come with, which creates a new user experience. In this hour, you’ll learn to use the accelerometer, which reports the angle at which your iPhone is tilted, Core Location, which tells you the location of your iPhone, and the camera, which lets you take pictures and short videos.
