iADS in Unity??

To show iads in my game, all I have to do is create a empty game object and attach the script found here to it: http://docs.unity3d.com/ScriptReference/ADBannerView.html ? Is there anything I need to set up on my iAds dashboard or in iTunes connect? Also with Unity 4.6.1f1, is there anything I should know about/do to ensure my game doesn't get rejected for iads complications? Because right now, I'm not seeing any ads when I run on my iPad Air.
