title: Populate cellForRowAtIndexPath for grouped tableview
body: <p>I have a uitableview (NOT a UITableViewController) with 2 sections inside the uitableview. For the other methods I was able to rely on a switch case to figure out what section should be populated with the correct data.</p>
  
  <pre><code>switch(section) {
      case 0:
         return postitiveArray.count
  
      case 1:
         return negativeArray.count
  
      default :return 0
  }
  </code></pre>
  
  <p>But cellForRowAtIndexPath doesn't seem to have that option. So how can I populate one section with postitiveArray and the other section with negativeArray?</p>
