Change Text Color of Items in UIActionSheet - iOS 8

I had been using following code to change text color of items which I add in

UIActionSheet
.:

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


It works fine in
iOS7
, but in
iOS8
the above code doesn't change the text color of items.

Now my question is how to change the text color of items which I add in
UIActionSheet
using
iOS8
??



Additional Info:

I added breakpoint to see whether following lines from the above code get executed or not:

UIButton *button = (UIButton *)subview;
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];


These lines do not get executed. So,
if([subview isKindOfClass:[UIButton class]])
is always
false
for all items of
actionSheet.subviews
. So what I think is that the view heirarchy of
UIActionSheet
has been changed.

Answer

There's an easy way if you still want to use UIActionSheet instead of UIAlertController in order to support older iOS versions.

UIActionSheet actually uses UIAlertController in iOS 8, and it has a private property _alertController.

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.
}
