swift - 中心和粗体 TextView swift

Question

大家好，我正在尝试为我的 TextView 设置粗体和居中， View 中有 3 种不同的颜色，但我希望更改的 2 种颜色居中。有没有办法做到这一点？下面是我的代码。

        let myString:String = DisplayableContents.texts[10]
        var myMutableString = NSMutableAttributedString()


        myMutableString = NSMutableAttributedString(string: myString, attributes: [NSFontAttributeName:UIFont(name: "Calibri", size: 17.0)!])

        myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.red, range: NSRange(location:74, length:96))
        myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.gray, range: NSRange(location:96, length:19))

        // set label Attribute

        infoBox.attributedText = myMutableString

Answer 1

尝试使用

    let myString:String = DisplayableContents.texts[10]
    var myMutableString = NSMutableAttributedString()

    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.alignment = NSTextAlignment.Center

    myMutableString = NSMutableAttributedString(string: myString, attributes: [NSParagraphStyleAttributeName:paragraphStyle, NSFontAttributeName:UIFont(name: "Calibri", size: 17.0)!])

    myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.red, range: NSRange(location:74, length:96))
    myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.gray, range: NSRange(location:96, length:19))

    // set label Attribute

    infoBox.attributedText = myMutableString

但是 iOS 中不存在“Calibri”。您可以在 http://iosfonts.com/ 中查看字体。如果您要将字体添加到项目中，请检查其粗体变体，可能是“Calibri-Bold”
