You could draw the gradient to an image context, get the pixel buffer for the image, then create a color from that pixel (see this post).
Otherwise,
CGGradientRefis an opaque type, and there isn't any way to get information out of it. For my own apps, I've also created a wrapper object aroundCGGradientRefthat creates the gradient and stores the colors / locations it was created with.
