title: how to scroll tableview or scrollview in storyboard preview
body: <p>I have a static tableview controller in storyboard representing a long form.
  I want to see the different localizations of the scene in storyboard <strong>preview</strong>, but I am not able to see the cells whose position exceeds the bounds of the actually chosen iPhone screen. </p>
  
  <p>How do I make the tableview scroll in the preview window?</p>
  
  <p>This question also applies to scrollviews.</p>
  
  <p>(I have found similar questions, like <a href="https://stackoverflow.com/questions/33714764/how-to-scroll-storyboard-preview">How to scroll storyboard preview?</a> or <a href="https://stackoverflow.com/questions/19029893/how-to-scroll-uitableview-in-storyboard-editor-of-xcode-5">How to scroll UITableView in Storyboard editor of Xcode 5?</a>, but none of them matches my specific question. There is one question that might match mine, but it's too vague to know for sure, and has no answers yet: <a href="https://stackoverflow.com/questions/38233536/xcode7-swift-storyboard-preview-not-able-to-scroll">xcode7 swift storyboard preview not able to scroll</a>.)</p>
