func loadWebView(htmlString : String) { 
     //Give HTML file a name: 
     //Constants.kTempFiled 

     let htmlFileName: NSString = "file.html" 

     //Create a reference to the temporary directory that will store the HTML file: 
     let tempDirectory: NSString = NSTemporaryDirectory() as NSString 

     //Append reference temporary directory to include HTML file name: 
     let htmlFilePath: NSString = tempDirectory.appendingPathComponent(htmlFileName as String) as NSString as NSString 

     //Convert appended temporary directory NSString to an NSURL object: 
     let htmlUrl = NSURL(fileURLWithPath: htmlFilePath as String) 


     //Below, HTML string is written to a file: 
     do { try htmlString.write(toFile: htmlFilePath as String, atomically: true, encoding: String.Encoding.utf8) } 
     catch { } 

     //HTML file URL is fetched and displayed in UIWebView: 
     webView.loadRequest(NSURLRequest(URL: htmlUrl)) 

    }
