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.
