Step 3: Add a text view to the view controller

- Add an IBOutlet UITextView property to the interface in the implementation file
- Add a UITextView just under the title field the view controller in your XIB
- Wire up the UITextView 'referencing outlet' to the 'textView' outlet on the view controller
- Declare the viewcontroller as a UITextViewDelegate
