title: How to fix the position of MBProgressHUD to center in a UITableView
body: <p>I have a scenario where I am using third party library <a href="https://github.com/jdg/MBProgressHUD">MBProgressHUD</a> on a <strong>UITableViewController</strong> but the issues is whenever I scroll up and down the HUD moves with the scroll. </p>
  
  <p>I don't want to disable the UITableView scroll and also I want to keep the HUD in the centre of the UITableView. </p>
  
  <p>Is there a possible way of implementing it?</p>
