改变 CALayer 的填充颜色

Question

Is it possible to set the fill color of a CALayer that has already been drawn on screen?

I am using SVGKit to load a SVG image into a UIView and everything is working very well but I need to change the fill color. I have read up on CAShapeLayer.fillColor and think that it can be done easily but I don't seem to see an easy way to do it with a CALayer? I really do hope it can be done.

May be someone might even be able to suggest if a CALayer can be converted to a CAShapeLayer?

Look at the docs for CALayer and you'll see

@property CGColorRef backgroundColor
