Used to pull spacial information from the device in either quaternion, rotation matrix or with 3D angles (roll, pitch and yaw).

Remarks
This class describes the attitude of the device (see MonoTouch.CoreMotion.CMAttitude) relative to an initial attitude (see CMMotionManager.StartDeviceMotionUpdates(CMAttitudeReferenceFrame)). The axes of rotation are defined as:
If a device's original orientation is lying flat on a table, with the bottom of the device facing the user:
| Change: | Rotation Around: | Caused By: |
|---|---|---|
| +Yaw | Z | The device is rotated counter-clockwise without lifting any edges. |
| +Pitch | X | The device is rotated towards its bottom. |
| +Roll | Y | The device is rotated towards its right side. |
The attitude can be retrieved using either:
| Form | Property: |
|---|---|
| Euler Angles | CMAttitude.Roll, CMAttitude.Pitch, CMAttitude.Yaw. |
| Rotation Matrix | CMAttitude.RotationMatrix. |
| Quaternion | MonoTouch.CoreMotion.Quaternion |
