How to change UIAlertController button text colour in iOS9?

The question is similar to iOS 8 UIActivityViewController and UIAlertController button text color uses window's tintColor but in iOS 9.

I have a UIAlertController and the dismiss button keeps white colour even I have tried to set

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

UIAlertController *strongController = [UIAlertController alertControllerWithTitle:title
strongController.view.tintColor = [UIColor black];

I've run into something similar in the past and the issue seems to stem from the fact that the alert controller's view isn't ready to accept tintColor changes before it's presented. Alternatively, try setting the tint color AFTER you present your alert controller:

[self presentViewController:strongController animated:YES completion:nil];
strongController.view.tintColor = [UIColor black];
