CMDeviceMotion - NSHipster
Beneath the smooth glass of each shiny iPhone, nestled on a logic board between touch screen controllers and Apple-designed SoCs, the gyroscope and accelerometer sit largely neglected.

Need it be so? The Core Motion framework makes it surprisingly easy to harness these sensors, opening the door to user interactions above and beyond the tapping and swiping we do every day.

For devices that include the M7 or M8 motion processor, the Core Motion framework also provides access to stored motion activity, such as step counts, stairs climbed, and movement type (walking, cycling, etc.).

Core Motion allows a developer to observe and respond to the motion and orientation of an iOS device by inspecting the raw and processed data from a combination of built-in sensors, including the accelerometer, gyroscope, and magnetometer.

Both accelerometer and gyroscope data are presented in terms of three axes that run through the iOS device. For an iPhone held in portrait orientation, the X axis runs through the device from left (negative values) to right (positive values), the Y axis through the device from bottom (-) to top (+), and the Z axis runs perpendicularly through the screen from the back (-) to the front (+).

The composited device motion data are presented in a few different ways, each with their own uses, as we'll see below.
