Loading Overview A CMMotionManager object is the gateway to the motion services provided by iOS.
These services provide an app with accelerometer data, rotation-rate data, magnetometer data, and other device-motion data such as attitude. These types of data originate with a device’s accelerometers and (on some models) its magnetometer and gyroscope. After creating an instance of CMMotionManager, an app can use it to receive four types of motion: raw accelerometer data, raw gyroscope data, raw magnetometer data, and processed device-motion data (which includes accelerometer, rotation-rate, and attitude measurements). The processed device-motion data provided by Core Motion’s sensor fusion algorithms gives the device’s attitude, rotation rate, calibrated magnetic fields, the direction of gravity, and the acceleration the user is imparting to the device.

I know this is not a physics class but the best way to define it is saying that it is a device to detect the magnitude and direction of acceleration. iDevices uses it to detect rotation, shake gestures, among others. To get started we are going open Xcode and go to File->New Project, in iPhone OS select Application and in the icons of the right double click “View-based Application”. Nothing new.
