Can we resize UITableViewCell without reloading it?

Question

Can we change the content size of UITableViewCell on click of a button inside it without reloading? When I do reloadData() or reloadCell() UITableView flickers and I want to avoid this flickering.

Answer 1

You should use beginUpdates() and endUpdates() to change content size of UITableViewCell, in this case heightForRowAtindexPath will called for each cell in tableView and update height of TableviewCell. for iOS > 10, You should prefer performBatchUpdates(_:completion:) instead of beginUpdates() and endUpdates().

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        self.tableView.beginUpdates()
        self.tableView.endUpdates()
}
