Change line width in CAShapeLayer

Question

I am working on a small project where I want to draw a Bezier curve. I want to be able to change lineWidth in different parts of the drawing.

Here is what I have:

 CAShapeLayer *pathLayer = [CAShapeLayer layer]; pathLayer.frame = self.animationLayer.bounds; pathLayer.bounds = pathRect; pathLayer.geometryFlipped = YES; pathLayer.path = path.CGPath; pathLayer.strokeColor = [[UIColor blackColor] CGColor]; pathLayer.fillColor = nil; pathLayer.lineWidth = 1.0f; pathLayer.lineJoin = kCALineJoinBevel; 

How can I change the line width? One solution might be to have multiple UIBezierPath with multiple CAShapeLayer s, but there should seem to be a simpler, more elegant solution (something like lineWidth lines at the level where the UIBezierPath lines UIBezierPath indicated).

Thanks!

Answer 1

UIBezierPath has only one lineWidth property, so it is not possible to use different line widths with one path. To achieve this effect, you will have to use several ways.
