Short answer: no.
Long answer: CAShapeLayer is a Core Animation layer (CALayer). You put it into your interface and it draws itself.
I know it's confusing, the way they use the word "layer", but CGContextDrawLayerAtPoint
has nothing to do with that (it's using the word "layer" in a totally different way, referring to a CGLayer, which is completely different and is used utterly differently). You've gone down the wrong rabbit hole here.
I could use
addSublayer:
to display the shape layer
Not could. Must. That is what you do with a CAShapeLayer.
The alternative you are looking for would be to pull the CGPath out of the CAShapeLayer and assign that path and stroke it, multiple times in multiple places, in a CGContext. But there is really no need to do that. iOS drawing is all about layers; don't be afraid of having multiple sublayers.
