Question

I am using UITableView with estimatedRowHeight and UITableViewAutomaticDimension. Also I am using NSFetchedResultsControllerDele

Answer 1

  func controller(controller: NSFetchedResultsController, didChangeObject anObject: AnyObject, atIndexPath indexPath: NSIndexPath?, forChangeType type: NSFetchedResultsChangeType, newIndexPath: NSIndexPath?) {
    switch type {
    case .Insert:

      tableView.insertRowsAtIndexPaths([newIndexPath!], withRowAnimation: .None)
        break

    case .Update:
        tableView.reloadRowsAtIndexPaths([indexPath!], withRowAnimation: .None)
        break

    case .Delete:
        tableView.deleteRowsAtIndexPaths([indexPath!], withRowAnimation: .None)
        break

    default: break;
    }
   tableView.reloadData()
  let indexPath = NSIndexPath(forRow: 0, inSection: 0)
  self. tableView.scrollToRowAtIndexPath(indexPath, atScrollPosition: .Top, animated: true)
   }

}
