Sort Colors (Objective-C)

Question

I\'m doing this sort of thing:

- (NSArray*)colors {
    float divisor = .3333;
    NSMutableArray *retVal = [NSMutableArray array];
    for (float one=0; one <

I think using [UIColor colorWithHue:saturation: brightness: alpha:] is your best bet. If you fix saturation, brightness and alpha and just use Hue you'll get all the colours in order.

Check out the wiki for HSB for more information.

for (float hsb = 0; hsb <= 1.0f; hsb += divisor) {
             UIColor *color = [UIColor colorWithHue:hsb saturation:1.0f brightness:1.0f alpha:.5f];
            [retVal addObject:color];
}
