If you are using a CGPath, then you will need to add the path to the CGContext and then fill the context.  You would most likely want to save/restore the context around this as well.

CGContextAddPath(context, path);
CGContextSetFillColorWithColor(context, color);
CGContextFillPath(context);


If you are using NSBezierPath, then it is a bit easier:

[color set];
[path fill];


Note: This code was written off the top of my head in mail.

Thanks,
Jon
