Instance Method


Yields the change in attitude given a specific attitude.


func multiply(byInverseOf attitude: CMAttitude)



An object representing the device’s attitude at a given moment of measurement.


This method multiplies the inverse of the specified CMAttitude object by the attitude represented by the receiving object. It replaces the receiving instance with the attitude change relative to the object passed in attitude. You should cache the CMAttitude instance you want to use as a reference and pass that object as the argument to subsequent calls of this method.
