Animate Radial Gradient

[Missing.Matter]

Hi all,

I need to animate a radial gradient, changing the inner radius to grow and shrink to make it look like it's pulsing.

It looks like CAGradientLayer is easily animatable, but that is only for linear gradients.

Is there a way to easily animate a CGGradient? Or is there a way to somehow create a radial gradient CAGradientLayer?

Or perhaps there is a different way of doing this which I'm not considering.

Please, and thoughts on these questions are appreciated.
