UIInterpolatingMotionEffect object maps the horizontal or vertical tilt of a device to values that you specify so that UIKit can apply those values to your views. You use this class to determine the amount of tilt along a single axis to apply to a view.
- iOS 7.0+
- tvOS 7.0+
After creating an instance of this class, you must assign appropriate values to the
maximumRelativeValue properties. As the user moves the device, the motion effect object translates the fixed offset values returned by the system (which are in the range
1) to the range of values you specified. UIKit then applies the translated values to any target views.
