NSMutableAttributedString作为UIAlertAction的标题-Swift [英] NSMutableAttributedString as UIAlertAction's title - Swift

问题描述

是否可以将NSMutableAttributedString设置为AlertAction的标题? 我的目标是在UIAlertAction标题中可视化设计良好的数学表达式.

Is it possible to set a NSMutableAttributedString as AlertAction's title? My aim is to visualize a math expression with a good design in my UIAlertAction's title.

let action = UIAlertAction(title: myNSMutableAttributedString, style: UIAlertActionStyle.default) {(result : UIAlertAction) -> Void in

}

预先感谢您的帮助.

推荐答案

不可能在不访问私有API的情况下将NSAttributedString用作UIAlertAction标题的方法将attributedTitle设置为属性字符串在这里不起作用(有关此问题的详细信息，请参见此问题).

It's not possible to use an NSAttributedString for a UIAlertAction's title without accessing private APIs, as the method for setting the attributedTitle to an attributed string does not work here (see this question for details on that).

我会为此创建一个自定义类或使用警报库.

I would create a custom class or use an alert library for this.
