Question

How does one draw a CGGradient with 3 colors?

I have an array like so:

CFArrayRef colors = (__bridge CFArrayRef) [NSArray arrayWithObjects:(id)lightGradientColor.CGColor,
                                           (id)darkGradientColor.CGColor, (id)lightGradientColor.CGColor,
                                           nil];

but I dont see the dark color in the middle with light on top and bottom sections, but rather just light on top, with dark until the bottom.

Have you tried specifying/verifying the locations of your colors? The range is [0…1]:

const CGFloat locations[3] = {0.0, 0.5, 1.0};
CGGradientRef grad = CGGradientCreateWithColors(colorspace, colors, locations);

note: The locations above should be the same as passing 0 for the locations parameter.
