您可以像这样在h3标签中应用颜色

let htmlString: String = "<html><body> <h3><font color=black>Some html string</font></h3> </body></html>"

let temphtmlString : NSString = (htmlString as NSString).stringByReplacingOccurrencesOfString("color=black", withString: "color=blue")


  let attrStr = try! NSAttributedString(
                data: temphtmlString.dataUsingEncoding(NSUnicodeStringEncoding, allowLossyConversion: true)!,
                options: [ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType],
                documentAttributes: nil)
txtView.attributedText = attrStr
