title: Make Scrollbar always visible on UITableView with reloadData()
body: <p>What I want to do is to show vertical scroll bar (indicator) always, even after I call tableView.reloadData().</p>
  
  <p>I found some good solution without reloadData(), like <a href="https://stackoverflow.com/a/15613852/8963597">https://stackoverflow.com/a/15613852/8963597</a> or <a href="https://stackoverflow.com/a/40890158/8963597">https://stackoverflow.com/a/40890158/8963597</a>, but once I do call reloadData() since the number of items and content of tableView should change, indicator shows a wrong position/has the wrong size (Sometimes, it should go away, since there is no need for scrolling)</p>
