swift - NSMutableAttributedString 中可能存在错误

Question

我正在尝试更改应在用户界面中显示的标签的字体。我用过这行:

let myAttribute = [ NSFontAttributeName: UIFont(name: "cirth1", size: 18.0)! ]
        let buttonTitleNSMut = NSMutableAttributedString(string: "\(buttonTitle)", attributes: myAttribute )
        let buttonTitle:String = "\(buttonTitleNSMut)"

        let button = createButtonWithTitle(buttonTitle as String)

但我的输出不是不同字体的标签，而是一个包含字体所有“规范”的长字符串......我究竟做错了什么？也许事实上我最后说它是一个String？

尝试下面的代码片段来实现您想要实现的目标。

   let plainText = "\(buttonTitle)" as NSString
   let attributedText = NSMutableAttributedString(string: plainText as String)

   attributedText.addAttribute(NSFontAttributeName: UIFont(name: "cirth1", size: 18.0)!)
   button?.titleLabel?.attributedText = attributedText

希望有帮助。
