    Connect the event to the action
    Add the IBOutlet and property to your view controller
    Next, synthesize the property...
    Connect the picker to our outlet
    Use your picker reference to pull the selected values

    We need data

    For the picker to actually show up, we have to give it data to display. And Mike is just the guy to help. He likes what you have put together for the UI, so now we need a little more information from him to give to the picker.
