Horizontal Gradient with a rounded rect path?

I have a custom UIView I'm drawing using CoreGraphics. Using CoreGraphics, how would I set a horizontal gradient and clip it to my rounded rect path while still using a shadow? I wrote as much as the path and I can fill it with a color using setFill, but the gradient (a horizontal one, too) isn't abiding by the path...

EDIT: Since 开发者_开发百科the time of posting (not so long ago), I figured out how to do a complex horizontal gradient, so now my only problem is drawing it within my CGContext's path.

Well it seems I've found my own answer:

CGContextAddPath(context, path);
CGContextClosePath(context);
CGContextClip(context);
CGContextDrawLinearGradient(context, gradient, startPt, endPt, 0);

Those lines of code perfectly clip it to the path of a rounded rect, or any path desired.
