Question

我想增加 html attributed string的字体尺寸。我也跟着this question但仍然无法正常工作。我使用下面的代码将html string更改为attributed string。

      let strmy = model.strItineraryDescription.html2AttributedString
      lblDescription.attributedText = strmy



extension String {
    var html2AttributedString: NSAttributedString? {
        do {
           return try NSAttributedString(data: Data(utf8), options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: String.Encoding.utf8.rawValue,NSFontAttributeName : UIFont.systemFont(ofSize: 20.0, weight: UIFontWeightSemibold)], documentAttributes:nil)



        } catch {
            print(error)
            return nil
        }
    }
    var html2String: String {
        return html2AttributedString?.string ?? ""
    }
}

我的html 字符串如下所示： -
