I call - (void)addCurveToPoint:(CGPoint)endPoint controlPoint1:(CGPoint)controlPoint1 controlPoint2:(CGPoint)controlPoint2; to create a curve path.

can I get every point.y from the path when I provide a point.x ？

Also a bezier curve can have multiple points with the same x coordinate. – Martin R Sep 06 '15 at 08:32
