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?

Answer 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.

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

Answer 2

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

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

Saved my day! Must be in answer! – Humanitarianism

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]]; – Excipient

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

Answer 3

For Actionsheet You can use

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];
        }
    }
}

However, this change is only temporary. If you tap and hold a button and release the touch outside of it, the color changes back to the default color. In fact it already changes to the default color on touch down. – Alms

Call [button setTitleColor:forControlState: instead for it to last. – Retaliate

Answer 4

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.

Answer 5

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.

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. – Frumenty

Answer 6

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

Thank you. It looks promising. – Frumenty

Answer 7

In iOS 6.0 create custom view in App delegate

.h
UIView* _loadingView;
    UIView* _subView;
    UIActivityIndicatorView*loadingIndicator;
    UITabBarController *tabBar_Controller;
    NSTimer *timer;


@property (strong, nonatomic) UIView* _loadingView;
@property (strong, nonatomic) UIView* _subView;



.m- (void)fadeScreen
{
    [UIView beginAnimations:nil context:nil]; // begins animation block
    [UIView setAnimationDuration:3.0]; // sets animation duration
    [UIView setAnimationDelegate:self]; // sets delegate for this block
    [UIView setAnimationDidStopSelector:@selector(finishedFading)];
    self.txtview.alpha = 0.0;  // Fades the alpha channel of this view
    [UIView commitAnimations];  // commits the animation block.  This
}



- (void) finishedFading
{
    [self.txtview removeFromSuperview];
}




- (void)showConnectivity:(NSString *)strTitle
{
    [_loadingView setBackgroundColor:[UIColor clearColor]];
    [_loadingView setAlpha:0.5];
    [_loadingView.layer setCornerRadius:10];
    [self.window addSubview:_loadingView];
    [_loadingView setHidden:NO];

    [_subView.layer setCornerRadius:7];
    [_subView setBackgroundColor:[UIColor colorWithHue:0.0f saturation:0.0f brightness:0.0f alpha:0.6]];
    [_subView setOpaque:YES];
    [self.window addSubview:_subView];
    [_subView setHidden:NO];

    [_loadingView setHidden:NO];
    [_subView setHidden:NO];

    loadingIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    [loadingIndicator setFrame:CGRectMake(85,10,35,35)];
    [_subView addSubview:loadingIndicator];
    [loadingIndicator setBackgroundColor:[UIColor redColor]];
    [loadingIndicator startAnimating];

    UILabel *_lab=[[UILabel alloc]initWithFrame:CGRectMake(8,10,72,45)];
    [_lab setText:strTitle];
    [_lab setTextColor:[UIColor whiteColor]];
    [_lab setBackgroundColor:[UIColor clearColor]];
    [_lab setFont:[UIFont boldSystemFontOfSize:13.0]];
    [_lab setTextAlignment:NSTextAlignmentCenter];
    [_subView addSubview:_lab];


}

- (void)CoonectingViewHidden
{

    [_loadingView setHidden:YES];
    [_subView setHidden:YES];

    NSArray *_aryViews = [_subView subviews];
    for(int i = 0; i<[_aryViews count];i++)
    {
        id obj = [_aryViews objectAtIndex:i];
        if(![obj isKindOfClass:[UIActivityIndicatorView class]])
            [obj removeFromSuperview];
    }
    [loadingIndicator stopAnimating];
    [loadingIndicator hidesWhenStopped];

}



in using .m
#import"Appdelegate.h"

- (void)showLoadingIndicator:(NSString *)message
{
    AppDelegate *delegateObj2=(AppDelegate *)[UIApplication sharedApplication].delegate;
    [delegateObj2 showConnectivity:message];
}
-(void)stopLoading
{
    AppDelegate *delegateObj3=(AppDelegate *)[UIApplication sharedApplication].delegate;
    [delegateObj3 CoonectingViewHidden];

}



// [self showLoadingIndicator:@"Loading"];
n

[self stopLoading];
