I'm trying to calculate the time of motion (either walking or running). Every CMMotionActivity object has a startDate property that indicates the time at which the activity started. But there is no indication the end time.
Is there any solution?
Every CMMotionActivity object is succeeded by another CMMotionActivity object. Each has a startDate property that indicates the time at which the activity started. Thus, the end time of each CMMotionActivity object is given by the startDate of its successor.
