UIAlertController Cancel action background color

Question

My question is similar to this where I couldn't find the answer.

UIAlertController change background color of Cancel button for action sheet and this alertController with white borders I want the cancel button with actionStyle as "Cancel" and the background should be of different colour(By default it will be white). How to change the background colour of Cancel button. I don't want to change the actionStyle to default. Is there any other way to achieve this? This is my code

   func showActionSheet(_ changeAction: UIAlertAction) {
    let alertController = UIAlertController(title: "", message: "Are you sure".localize(), preferredStyle: .actionSheet)
    alertController.view.tintColor = UIColor.green
    if let subview = alertController.view.subviews.first, let alertContentView = subview.subviews.first {
        for innerView in alertContentView.subviews {
            innerView.backgroundColor = UIColor.red
        }
    }
    let cancelAction = UIAlertAction(title: "Cancel".localize(), style: .cancel) { _ in
        self.doneButton.isEnabled = true
    }
    alertController.addAction(changeAction)
    alertController.addAction(cancelAction)
    self.present(alertController, animated: true)
}

In one of the question answer there is a hack, but i would prefer to create my custom alert. https://stackoverflow.com/a/44721186/1031944 — Hamdullah shah, Jul 03 '17 at 14:37
I want the background color of Cancel action to be changed. Not the font or text(Cancel). @SamarthKejriwal — vinny, Jul 03 '17 at 15:02
@Hamdullahshah There is the change in the color of Cancel(text). I want the background to be changed from white color — vinny, Jul 03 '17 at 15:03
You will have to create a custom alert view ,because changing the background color for the action button is not supported in the xcode library — Samarth Kejriwal, Jul 03 '17 at 15:03
@SamarthKejriwal Do you have any reference link for that? If please provide them — vinny, Jul 03 '17 at 15:04

It's possible to change it using UIAppearance and a little hack. See my answer here
