Setting Colors for Buttons Instead of Images?

[vicc]

Is there a way to define the button using uicolors rather than enum's for images?

That would be cool

Just came across this project and wanting the same thing. As your posts are old, don't know if you still need the help, but in any case, heres what I did.

Added:

- (UIImage *)imageFromColor:(UIColor *)color {
    CGRect rect = CGRectMake(0, 0, 1, 1);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

Then for the buttons in buttonForItemIndex:

    switch (item.type) {
        case SIAlertViewButtonTypeCancel:
            normalImage = [self imageFromColor:[UIColor colorWithRed:0.271 green:0.271 blue:0.271 alpha:0.75]];
            highlightedImage = [self imageFromColor:[UIColor colorWithRed:0.271 green:0.271 blue:0.271 alpha:1]];

            [button setTitleColor:self.cancelButtonColor forState:UIControlStateNormal];
            [button setTitleColor:[self.cancelButtonColor colorWithAlphaComponent:0.8] forState:UIControlStateHighlighted];
            break;

        case SIAlertViewButtonTypeDestructive:
            normalImage = [self imageFromColor:[UIColor colorWithRed:0.678 green:0.161 blue:0.188 alpha:0.50]];
            highlightedImage = [self imageFromColor:[UIColor colorWithRed:0.678 green:0.161 blue:0.188 alpha:0.65]];

            [button setTitleColor:self.destructiveButtonColor forState:UIControlStateNormal];
            [button setTitleColor:[self.destructiveButtonColor colorWithAlphaComponent:0.8] forState:UIControlStateHighlighted];
            break;

        case SIAlertViewButtonTypeDefault:
        default:
            normalImage = [self imageFromColor:[UIColor colorWithRed:0.271 green:0.271 blue:0.271 alpha:0.75]];
            highlightedImage = [self imageFromColor:[UIColor colorWithRed:0.271 green:0.271 blue:0.271 alpha:1]];

            [button setTitleColor:self.buttonColor forState:UIControlStateNormal];
            [button setTitleColor:[self.buttonColor colorWithAlphaComponent:0.8] forState:UIControlStateHighlighted];
            break;
    }

Obviously defining corner radius would look ideal too:
button.layer.cornerRadius = 8;
button.clipsToBounds = YES;

Customizing font, title, word wrap etc to fit your styling needs, but that's the jist of what I did.

Hope this helps.
