title: UIWebView for GIF Background loadData method error
body: <p>I keep receiving the same error of: Cannot invoke loadData with an argument of list type '(NSData, MIMEType: String, textEncodingName: nil, baseURL: nil)'</p>
  
  <p>for the loadData method.</p>
  
  <pre><code>var filePath = NSBundle.mainBundle().pathForResource("fractal", ofType: "gif")
  
  var gif = NSData(contentsOfFile: filePath!)
  
  var webViewBG = UIWebView(frame: self.view.frame)
  
  webViewBG.loadData(gif!,MIMEType: "image/gif",textEncodingName: nil,baseURL: nil) // this line of code causes the build error
  </code></pre>
