Change tint color of UIAlertview and UIActionsheet buttons

Question

I am trying to adapt my application for iOS 7. The issue I am having is I can not change the tint color of some controls.

I did add

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
if (IOS7_OR_LATER)
    self.window.tintColor = [self greenTintColor];

to my app delegate's

           - (BOOL)application:(UIApplication *)application
 didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

It mostly helped but color of message box and action sheet buttons is still the default blue.

How can I recolor all such buttons too?

Some screenshots:

Solution 1

As UIAlertView is deprecated You can. Use UIAlertController.

You can use tintColor property.

OLD

The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.

-From Apple Doc

You can use tintColor property or You can use Some Custom Library for that, you can find it at cocoacontrols.com.

Solution 2

I was able to change the cancel button's text color to white in app delegate.

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

Solution 3

Combining best answers above, and updated for deprecation:

[[UIView appearanceWhenContainedInInstancesOfClasses:@[[UIAlertController class]]] setTintColor:[UIColor greenColor]];

or Swift:

UIView.appearance(whenContainedInInstancesOf: [UIAlertController.self]).tintColor = .green

Works in 2018, Swift 4 / iOS 12.

Solution 4

You can adjust the color by searching and modifying the UILabel in the subview hierarchy of the alert window that is created right after showing the alert:

- (void)setButtonColor:(UIColor*)buttonColor {
    dispatch_after(dispatch_time(0,1), dispatch_get_main_queue(), ^{
        NSMutableArray *buttonTitles = [NSMutableArray array];
        for (NSUInteger index = 0; index < self.numberOfButtons; index++) {
            [buttonTitles addObject:[self buttonTitleAtIndex:index]];
        }
        for (UILabel *label in [[[UIApplication sharedApplication] keyWindow] recursiveSubviewsOfKind:UILabel.class]) {
            if ([buttonTitles containsObject:label.text]) {
                label.textColor = buttonColor;
                label.highlightedTextColor = buttonColor;
            }
        }
    });
}

[alert show];
[alert setButtonColor:UIColor.redColor];

The recursiveSubviewsOfKind: method is a category on UIView that returns an array of views in the complete subview hierarchy of the given class or subclass.

Solution 5

for UIAlertView with colored buttons you can use the cocoapod "SDCAlertView"

Thank you. This works for UIAlertView but there are also UIBarButtonItems, for example. For UIBarButtonItem the effect is temporary: color reverts to default after tap or after pressing and holding the button.

[Bobrovsky]

Thank you. It looks promising.

In iOS 8 there is alert.view.tintColor = UIColor.redColor()

Saved my day! Must be in answer!

Well, it does more than it should. I would rather use [[UIView appearanceWhenContainedIn:[UIAlertView class], nil] setTintColor:[UIColor whiteColor]]; and [[UIView appearanceWhenContainedIn:[UIAlertController class], nil] setTintColor:[UIColor whiteColor]];

I'd rather @KévinRenella's answer as well. Ali's answer is very dangerous.

[Tarek Hallak]

Answer has been copied from stackoverflow.com/a/19198435/1262634 ,at least change the text!

@KévinRenella what would be the swift version of your improved answer?

[Kévin Renella]

@DanielSpringer Even I am sure you could find this by yourself ;) UIView.appearance(whenContainedInInstancesOf: [UIAlertView.self]).tintColor = UIColor.white and UIView.appearance(whenContainedInInstancesOf: [UIAlertController.self]).tintColor = UIColor.white

[Kévin Renella]

@DanielSpringer Now, the right answer using UIAlertController is to set the tintColor on the view of the controller. For example: alertController.view.tintColor = UIColor.white

What I was missing was the .self in [UIAlertView.self]. I ended up figuring it out, but Xcode's errors weren't clear. Other than that, I did find it myself. 😉 Thanks!
