title: popover segue with no anchor, MKMapView
body: <p>I'm trying to present a popover over a pin I added to a MKMapView.  I added a UIViewController to my storyboard, and dragged a segue from the MKMapView in one view controller to the viewController I want to show in my popover and selected popover.  I get the error:</p>
  
  <pre><code>Popover segue with no anchor
  </code></pre>
  
  <p>In IB, I see "Drag to select an anchor", but when I try dragging it anywhere within the first viewController that has the MKMapView in it, nothing gets selected.  I'm not sure where to go from here and if popover's from a view that is created dynamically can be used to present a popover with Storyboards.  I know I can do it in code, but then I have to copy and paste my setters in prepareForSegue:.  Thoughts?  Thanks.</p>
