CoreMotion framework implements many motion-related classes. The functionality for these classes varies from counting steps with
CMStepCounter to figuring out the user's altitude with
CMAltimeter to accessing gyroscope data with
CMGyroData or even to reading whether a user is walking, running, or driving with
CMMotionActivityManager. Reading the hardware sensors, such as the gyroscope, is done through an instance of
CMMotionManager. The motion manager class provides an interface that enables developers to read data from the accelerometer, gyroscope, and more.
Our application will use a combination of sensors to function properly. However, before we get to that, we'll explore the available sensors a bit more because there ...
