title: Using custom controls with Interface Builder
body: <p>I have a custom  ViewController which allows selection of an image from a grid. The ViewController uses the AQGrid control and is really just a modified version of the samples shipped with AQGrid.</p>
  
  <p>I'm trying to hook it up in InterfaceBuilder, but documentation on how to do this seems sparse. In standard Cocoa apparently I should create an IB plugin to use with IB, but I'm just looking for the quickest option really as there are a few of these custom ViewControllers which I need to hook up (including a rating control). I've also tried dragging the "Object" controller in IB to my tabpage, but it just gets added to the tree outside of the tabcontroller (see screenshot).</p>
