Instance Property

majorRadiusTolerance

The tolerance (in points) of the touch’s radius.

Declaration

var majorRadiusTolerance: CGFloat { get }

Discussion

This value determines the accuracy of the value in the majorRadius property. Add this value to the radius to get the maximum touch radius. Subtract the value to get the minimum touch radius.
