UITableViewCell Set selected initially

For the cell to appear selected, you have to call -setSelected:animated: from within -tableView:willDisplayCell:forRowAtIndexPath: like so:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (/* should be selected */) {
        [cell setSelected:YES animated:NO];
    }
}

Calling -setSelected from anywhere else has no effect.

try this

NSIndexPath* selectedCellIndexPath= [NSIndexPath indexPathForRow:0 inSection:0];
[self tableView:tableViewList didSelectRowAtIndexPath:selectedCellIndexPath];
[tableViewList selectRowAtIndexPath:selectedCellIndexPath animated:YES scrollPosition:UITableViewScrollPositionNone];

OR

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (/* should be selected */) {
        [cell setSelected:YES animated:NO];
    }
}

Swift 4 version is

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    func shouldSelect() -> Bool {
        // Some checks
    }
    if shouldSelect() {
            tableView.selectRow(at: indexPath, animated: false, scrollPosition: .none)
    }
}
