CGContextSetFillColorWithColor(g, [UIColor greyColor].CGColor);

I'm trying to follow O'Reilly's iPhone Game Development book on page 73 Chapter 3 but I'm running into a compile error that states

error: request for member 'CGColor' in something not a structure or union

According to the book's errata page this is an unconfirmed errata in the book. I'm hoping that someone could help me replace that line of code to something that works. The example project can be downloaded from sourceforge at this link.
