title: UIView outside of a View Controller in a Storyboard
body: <p>I'm stuck with a question I can't find an answer to in the official documentation, on Stackoverflow or on Google. </p>
  
  <p>I'm an experienced iOS developer but new to Storyboards. I'd like to instantiate a view on the current viewcontroller, a view that, in a NIB, I would draw outside the viewController and attach an outlet to to refer to it in code and call something like addSubview: or so. It's useful to draw an overlay or, in my current case, a callout view for use in a MapView delegate. But I can't figure out how I can do this in a Storyboard. </p>
  
  <p>I can't seem to have a view outside of a viewcontroller, and views inside the viewcontroller either have to be subviews of the controller's view or don't be visible in Interface Builder at all (which is okay when you drag a view composed outside, in a traditional NIB, but quite a problem if you need to tweak even the least detail of it). </p>
  
  <p>Any hint on what to do or where to look? Thanks. </p>
