super.configureActionButton(button, at: style)switch style {case.ok:
button.titleLabel?.font =UIFont.boldSystemFont(ofSize:20)
button.setTitleColor(UIColor.gray, for:UIControlState())case.cancel:
button.backgroundColor =UIColor.darkGray
button.setTitleColor(UIColor.white, for:UIControlState())case.default:
button.setTitleColor(UIColor.lightGray, for:UIControlState())default:break}}overridefunc configureContentView(_ contentView:AlertContentView){
super.configureContentView(contentView)
contentView.titleLabel.textColor =UIColor.lightGray
contentView.titleLabel.font =UIFont.boldSystemFont(ofSize:30)
contentView.messageLabel.textColor =UIColor.lightGray
