title: How to call didSelectRowAtIndexPath before prepareForSegue?
body: <p>I'm making iOS app which is tableview base.
  Here's what I want to do.
  Tableview1 -> Tableview2
  Once I select one of tableCell, new tableView2 is shown.
  I'd like to hilight the cell before new tableView is shown.
  Nonetheless, hilight is so slow because of loading new tableView data.
  I looked up this. The reason why is <code>prepareForSegue</code> is called before <code>didSelectRowAtIndexPath</code>.</p>
  
  <p>Then could you tell me how to call <code>didSelectRowAtIndexPath</code> before <code>prepareForSegue</code>?</p>
  
  <p>Or tell me how to set up table cell when cell is selected.</p>
  
  <p>All the best.</p>
