Instance Property


An array of NSNumber objects that define the position of the curve relative to a control point.


var biasValues: [NSNumber]? { get set }


This property is used only for the cubic calculation modes. Positive values move the curve before the control point while negative values move it after the control point. The first value defines the behavior of the tangent to the first control point, the second value controls the second point’s tangents, and so on. If you do not specify a value for a given control point, the value 0 is used.
