In iOS 7, how do I change the color of the options in my UIActionSheet?

Question

I use green as the "action color" throughout my app, and I want the options in my UIActionSheets to be green as well, for consistency. How can I change the colour of the UIActionSheet options to green from blue?

Answer 1

Utilize the willPresentActionSheet delegate method of UIActionSheet to change the action sheet button color.

- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
    for (UIView *subview in actionSheet.subviews) {
        if ([subview isKindOfClass:[UIButton class]]) {
            UIButton *button = (UIButton *)subview;
            button.titleLabel.textColor = [UIColor greenColor];
        }
    }
}

This answer is better. Uses a delegate method not to mention more concise. Also the above answer doesn't change the cancel button's color. – Spradling

For some reason, if you also want to change the font, you have to do that before changing the color, or it won't work – Loop

@BrenoGazzola: What happens? – Upcountry

When doing button.titleLabel.textColor = MY_COLOR;button.titleLabel.font = MY_FONT; the options were changed to the new font but remained blue and red. Simply changing the order to button.titleLabel.font = MY_FONT;button.titleLabel.textColor = MY_COLOR; fixed the problem and I got both the new font and new colors. – Loop

That is strange. Which version of iOS are you running and what device/simulator are you using to run the code? If I can replicate this tonight, I'll submit a bug ticket to apple. – Upcountry

don't forget to set the button's color for selected states as well! #7807340 Regular buttons will use UIControlStateHighlighted when tapped, but the Cancel button will use UIControlStateSelected – Zeb

You could do something like this:

// Your code to instantiate the UIActionSheet
UIActionSheet *actionSheet = [[UIActionSheet alloc] init];
// Configure actionSheet

// Iterate through the sub views of the action sheet
for (id actionSheetSubview in actionSheet.subviews) {
    // Change the font color if the sub view is a UIButton
    if ([actionSheetSubview isKindOfClass:[UIButton class]]) {
        UIButton *button = (UIButton *)actionSheetSubview;
        [button setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
        [button setTitleColor:[UIColor greenColor] forState:UIControlStateSelected];
        [button setTitleColor:[UIColor greenColor] forState:UIControlStateHighlighted];

    }
}

If you're going to reuse this a lot, I'd subclass UIActionSheet and use this code.

Is that using private APIs? – Innoxious

No, it is just accessing all the subviews of a UIActionSheet and finding the buttons – Tibbitts

When you tap it it changes back to blue. – Innoxious

Did you manage to make it work for the cancel button ? Mine keep geting it's previous color – Puncheon

Answer 3

You can change easily the application's tint color using this short function on your AppDelegate didFinishLaunchingWithOptions method.

[[UIView appearance] setTintColor:[UIColor redColor]];

Hope it will help you :)
