Question

有一种更改UIAlertAction字体的方法，因为我仅在UIAlertController的标题和消息中发现了如何更改字体。我还找到了如何更改颜色，但我只是找不到更改字体的方法。

Answer 1

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)

如何更改UIAlertAction字体？
