UITableView Flickering with UIRefreshControl

I guess the issue is using estimatedHeight & UITableViewAutomaticDimension along with uitableview's reloadData. This has been reported here

The delay would work but its still not the right way to achieve it unless you want a hackish work around.

Swift

You may want to use

extendedLayoutIncludesOpaqueBars = true

in your ViewController in order to have correct UIRefreshControl animation.

I got the same issue today and I managed to solve the problem using CATransaction, here is a code snippet in Swift, executed within a UITableViewController :

        CATransaction.begin()
        CATransaction.setCompletionBlock { () -> Void in
            /*wait for endRefreshing animation to complete 
              before reloadData so table view does not flicker to top 
              then continue endRefreshing animation */

            self.tableView.reloadData()
        }

        self.refreshControl!.endRefreshing()
        CATransaction.commit()

The problem is that you are calling -reloadData and -endRefreshing together. Both want to update the view. You need to separate them a bit.

One of these options will work, depending on where you want to see the cells update:

[self.tableView reloadData];
[self.refreshControl performSelector:@selector(endRefreshing) withObject:nil afterDelay:0.5];

[self.refreshControl endRefreshing];
[self.tableView performSelector:@selector(reloadData) withObject:nil afterDelay:0.5];

Probably you need less delay with the first option. Even 0.0 seconds seemed to work in your example code. That's enough to get the -endRefreshing animation on the next screen refresh.
