Comment changer la taille et la taille des caractères des balises html dans swift 3?

Question

Je ne peux pas modifier la couleur du texte de la balise html et la taille de la police. Quelqu'un peut-il m'aider à résoudre ce problème?

let cell = tableView.dequeueReusableCell(withIdentifier: "descriptioncell", for: indexPath) as! DescriptionTableViewCell 
let attrStr = try! NSAttributedString(data: (descriptionAttribute?.data(using: String.Encoding.unicode, allowLossyConversion: true)!)!, 
                options: [ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], 
                documentAttributes: nil) 
cell.descriptionTextView.attributedText = attrStr

Vous devez utiliser NSMutableAttributedString pour atteindre vos besoins. Essayez ceci

func convertToInlineImageFormat(htmlStrr:String) -> NSMutableAttributedString { 

    let htmlStringgg = htmlStrr as String 
    let content = try! NSMutableAttributedString(
     data: htmlStringgg.data(using: String.Encoding.unicode, allowLossyConversion: true)!, 
     options: [ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], 
     documentAttributes: nil) 
    //  content.addAttribute(NSForegroundColorAttributeName, value: UIColor.white, range: NSRange(location: 0, length: htmlStrr.length)) 

    // Resizing Inline images 
    content.enumerateAttribute(NSAttachmentAttributeName, in: NSMakeRange(0, content.length), options: NSAttributedString.EnumerationOptions.init(rawValue: 0), using: { (value, range, stop) -> Void in 
     if let attachement = value as? NSTextAttachment { 
      let image = attachement.image(forBounds: attachement.bounds, textContainer: NSTextContainer(), characterIndex: range.location) 
      let screenSize: CGRect = UIScreen.main.bounds 
      if (image?.size.width)! > screenSize.width - 2 { 
       let newImage = image?.resizeImage(scale: (screenSize.width - 2)/(image?.size.width)!) 
       let newAttribut = NSTextAttachment() 

       newAttribut.image = newImage 
       content.addAttribute(NSAttachmentAttributeName, value: newAttribut, range: range) 

      } 
     } 
     // ARTICLE DESCRIPTION FONT 
     //   let replacementFont = Contants.descFont 

     let fontSizeDescribtion = UserDefaults.standard.float(forKey: "FontSize") 
     var fontSize :Float = 0.0 
     if fontSizeDescribtion == 0{ 
      fontSize = 18 
     }else{ 
      fontSize = Float(fontSizeDescribtion) 
     } 
     let fontDesc = UIFont(name: Contants.abiramiFont, size: CGFloat(Float(fontSize))) 

     content.addAttribute(NSFontAttributeName, value: fontDesc!, range: NSRange(location: 0, length: content.length)) 
     content.addAttribute(NSForegroundColorAttributeName, value: UIColor.black, range: NSRange(location: 0, length: content.length)) 

    }) // Content block 

    return content 
}
