Instance Method

addCurve(to:control1:control2:)

Adds a cubic Bézier curve to the current path, with the specified end point and control points.

Declaration

func addCurve(to end: CGPoint, control1: CGPoint, control2: CGPoint)

Parameters

end

The point, in user space coordinates, at which to end the curve.

control1

The first control point of the curve, in user space coordinates.

control2

The second control point of the curve, in user space coordinates.

Discussion

This method constructs a curve starting from the path's current point and ending at the specified end point, with curvature defined by the two control points. After this method appends that curve to the current path, the end point of the curve becomes the path's current point.
