Chapter 3. In this chapter we create a URL shortening app. This commit see's the Navigation Bar, Web View, and URL text filed added to the UIViewController.
Finishing chapter 3: The app is fully functional on iPhone & iPad. The app takes a URL, uses GoDaddy's URL shortening service and shortens the URL. We format the URL taken from the text field and encode it before sending it using a connection object, we then collect the data received and display it in the label at the bottom of the screen. The copy button then selects the shortened label and adds it to the pasteboard.
