Draw Graph curves with UIBezierPath

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

draw them as curves. 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...

Drawing bezier curves with my finger in iOS?

http://stackoverflow.com/questions/4672646/drawing-bezier-curves-with-my-finger-in-ios

ipad ios vector 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.. self setNeedsDisplay 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..
