Change tint color of UIAlertview and UIActionsheet

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?

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.
