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.
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.
}
For Swift Below code should works
let alertAction = UIAlertAction(title: "XXX", style: .default) { (action) in
}
alertAction.setValue(UIColor.red, forKey: "titleTextColor")
