如何更改UIAlertAction字体？

Question

有没有办法改变UIAlertAction字体，因为我只在UIAlertController的标题和消息中发现了如何改变字体。我也找到了改变颜色的方法，但是我就是找不到改变字体的方法。

let titleAttributed = NSMutableAttributedString(
        string: Constant.Strings.cancelAbsence, 
        attributes: [NSAttributedStringKey.font:UIFont(name:"FONT_NAME",size: FONT_SIZE)]
)

let messageAttributed = NSMutableAttributedString(
        string: Constant.Strings.cancelAbsence, 
        attributes: [NSAttributedStringKey.font:UIFont(name:"FONT_NAME",size: FONT_SIZE)]
)

let alertController = UIAlertController(
    title: "",
    message: "",
    preferredStyle: UIAlertControllerStyle.YOUR_STYLE
)

alertController.setValue(titleAttributed, forKey : "attributedTitle")
alertController.setValue(messageAttributed, forKey : "attributedMessage")
present(alertController, animated: true, completion: nil)
