Draw Graph curves with UIBezierPath

http://stackoverflow.com/questions/13719143/draw-graph-curves-with-uibezierpath

I'm well aware that UIBezierPath has following two functions to support this feature. Cubic curve addCurveToPoint controlPoint1 controlPoint2 Quadratic curve addQuadCurveToPoint controlPoint But problem is that I don't have control points. All i have..

bezier share improve this question If you want to stay in objective c you can use UIBezierPath's addCurveToPoint controlPoint1 controlPoint2 method. You can also use a similarly named function with CGPaths. When using bezier curves you need 4 points.. void _updateCurve UIBezierPath path UIBezierPath bezierPath path moveToPoint startPt path addCurveToPoint endPt controlPoint1 cPt1 controlPoint2 cPt2 void _calcDefaultControls if ABS startPt.x endPt.x ABS startPt.y endPt.y cPt1 CGPoint startPt.x..
