"5. To access this new view controller, add a bar button item to the navigation bar in the location table view's storyboard canvas. Set the _style_\ to "add" so it shows a + sign. In the FISLocationsTableViewController's viewDidLoad method, set this new button's accessibility label & identifier to @"addButton". You can access it as a property via self.navigationItem.rightBarButtonItem and set the string properties from there."
