How to unselect a uitableview cell when the user returns to the view controller

Solution 1:

If you using UITableViewController subclass then just set property

self.clearsSelectionOnViewWillAppear = YES;

else in viewWillAppear just call

NSIndexPath *indexPath = self.tableView.indexPathForSelectedRow;
if (indexPath) {
    [self.tableView deselectRowAtIndexPath:indexPath animated:animated];
}

// MARK: - Swift 3
if let indexPath = tableView.indexPathForSelectedRow {
    tableView.deselectRow(at: indexPath, animated: true)
}

Solution 2:

Swift 3.0

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    if let selectionIndexPath = self.tableView.indexPathForSelectedRow {
        self.tableView.deselectRow(at: selectionIndexPath, animated: animated)
    }
}

Solution 3:

try

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Deselect the row which was tapped
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}
