Change text color in UIActionSheet buttons

问题:

In my project, I am using UIActionSheet for displaying for some sorting type. I want to change the color of the text displayed in the action sheet buttons. How can we change the text color?

回答1:

iOS 8: UIActionSheet is deprecated. UIAlertController respects -[UIView tintColor], so this works:

alertController.view.tintColor = [UIColor redColor];

Better yet, set the whole window's tint color in your application delegate:

self.window.tintColor = [UIColor redColor];

iOS 7: In your action sheet delegate, implement -willPresentActionSheet: as follows:

- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
    for (UIView *subview in actionSheet.subviews) {
        if ([subview isKindOfClass:[UIButton class]]) {
            UIButton *button = (UIButton *)subview;
            [button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
        }
    }
}

回答2:

In iOS 8, none of this works anymore. UIActionSheet text seems to get its color from window.tintColor.

回答3:

This works for me in iOS8

[[UIView appearanceWhenContainedIn:[UIAlertController class], nil] setTintColor:[UIColor redColor]];

回答4:

If ever you want to go through the UIActionSheet's subviews, you should not directly set the text color of the UILabel but use the UIButton setTitleColor:forState method instead. Otherwise, the initial color will be set back upon events like UIControlEventTouchDragOutside for example.

Here is the proper way to do it, reusing the jrc's code:

- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
    for (UIView *subview in actionSheet.subviews) {
        if ([subview isKindOfClass:[UIButton class]]) {
            UIButton *button = (UIButton *)subview;
            [button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
        }
    }
}

回答5:

May be a late answer but I figure it could help someone.

iOS 8: You could simply initialize your UIAlertAction with the style: UIAlertActionStyleDestructive like so:

UIAlertAction *delete = [UIAlertAction actionWithTitle:@"Delete" style:UIAlertActionStyleDestructive handler:^(UIAlertAction *action){

   // your code in here   

}];

This will make the button's text red by default.

@jrc solution works, but titleLabel color changes when you tap the button. Try this to keep the same color at all states.

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

          [button setTitleColor:customTitleColor forState:UIControlStateHighlighted];
          [button setTitleColor:customTitleColor forState:UIControlStateNormal];
          [button setTitleColor:customTitleColor forState:UIControlStateSelected];
        }
      }
}

EDIT

Here is a similar question: How to customize Buttons in UIActionSheet?

Try to use the appearance protocol [NOT WORKING]

 UIButton *btn = [UIButton appearanceWhenContainedIn:[UIActionSheet class], nil];
 [btn setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

回答8:

use this for ios 8 and above

SEL selector = NSSelectorFromString(@"_alertController");
if ([actionSheet respondsToSelector:selector])
{
    UIAlertController *alertController = [actionSheet valueForKey:@"_alertController"];
    if ([alertController isKindOfClass:[UIAlertController class]])
    {
        alertController.view.tintColor = [UIColor blueColor];
    }
}
else
{
    // use other methods for iOS 7 or older.
}

回答9:

Soulution for Swift 3. Changes all colors.

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

回答10:

UIAppearance can handle this:

[[UIButton appearanceWhenContainedIn:[UIActionSheet class], nil] setTitleColor:[UIColor cyanColor] forState:UIControlStateNormal];

Much easier than going through the subviews, but I haven't tested this solution on iOS 6 or earlier.
