title: What design pattern best represents the "File Owner" object in the iPhone?
body: <p>I'm new to iPhone development. I'm reading that the "File Owner" in the xib is the responsible for instantiating all objects defined in the nib... some type of factory pattern comes to mind, but maybe I'm not looking at the big picture...</p>
  
  <p>So, what would be the closest design pattern (gof) associated with the "File Owner" concept?</p>
