Rubymotion - looking to get past basic http authentication when connecting to a URL with UIWebView..

WebViewController.rb

class WebViewController < UIViewController
  def viewDidLoad
    super

    @url = NSURL.URLWithString("<redacted>")
    request = NSURLRequest.requestWithURL(@url)

    connection = NSURLConnection.connectionWithRequest(request, delegate: self)

    self.view = UIWebView.alloc.init
  end

  def connection(connection, didReceiveAuthenticationChallenge: challenge)
    puts "Received auth challenge"

    cred = NSURLCredential.alloc.initWithUser("<redacted>",
             password: "<redacted>",
             persistence: NSURLCredentialPersistenceForSession)
    challenge.sender.useCredential(cred, forAuthenticationChallenge: challenge)
  end

  def connection(connection, didReceiveResponse: response)
    puts "didReceiveResponse"
    @initial_data = NSMutableData.alloc.init
  end

  def connection(connection, didFailWithError: error)
    puts "failed with error: #{error}"
  end

  def connection(connection, didReceiveData: data)
    puts "received incremental data"
    @initial_data.appendData data
  end

  def connectionDidFinishLoading(connection)
    puts "finished loading"
    self.view.loadData(initial_data, MIMEType: "text/html", textEncodingName: "UTF-8", baseURL: nil)
  end

  private

  attr_accessor :initial_data
end
