Instance Method

addQuadCurve(to:control:transform:)

Adds a quadratic Bézier curve to the path, with the specified end point and control point.

Declaration

func addQuadCurve(to end: CGPoint, control: CGPoint, transform: CGAffineTransform = .identity)

Parameters

end

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

control

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

transform

An affine transform to apply to the curve before adding to the path. Defaults to the identity transform if not specified.

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 control point. After this method appends that curve to the current path, the end point of the curve becomes the path’s current point.
