title: Have Interface Builder layout my content in a SplitViewControllers DetailView
body: <p>I was mocking about with Interface Builder and the DetailView of a SplitViewController.
  I have a UIImageVIew of size 700px by 700px in the detailView and nothing else, I would like it to always position itself in the center. Because it is 700x700 it should fit in both portrait and landscape. However, there is also a UIToolBar governing the top 44 pixels. If I use IB and set the UIImageViews contentMode to center and the detailViews contentMode to center, the UIImageView is positioned so that it covers a few pixels of the toolbar. (but in the center non the less)</p>
  
  <p>I have tried anchoring the UIImageView to the bottom, but it still positions itself in the center and the layout still covers the toolbar.</p>
  
  <p>How would I go about doing the layout as "UIImageView:Deduct the space the toolbar takes up and position your self in the center of the remaining view" ?</p>
  
  <p>Hope someone can help, the IB layout engine is a bit heavy to figure out by trial and error:)</p>
  
  <p>Thank you in advance.</p>
