I define custom UITableViewCell in storyboard with autolayout, and I set the UITableView's rowHeight as UITableViewAutomaticDimension, all things go will.
Here I fetch more date I get a problem. if I scroll to the bottom of tableView, and then fetch more items to the date source of the tableview, reload tableView, and scroll up, when a new cell displayed, the tableView will jump, the cell which would scroll out of screen is jump to the screen. I want the tableView scroll smoothly.
How could I fix it?
