Hi, I am using the CAShapeLayer's ability to animate a path, but the start and end path need to have the same number of segments.
I have been using CGPathAddArcToPoint to add the curves to my path. That translates to CGPathAddCurveToPoint calls behind the scenes, but sometimes it adds one curve and sometimes two, which means that the curve can't be animated.
I therefore need to be able to approximate the arc with the same number of CGPathAddCurveToPoint calls each time (presumably 2 or 3).
Has anyone done this already either with CGPaths or NSBezierPaths? Any pointers would be most welcome.
Thanks
Gideon
