Question

I have a table view with numerous cells. When I press one, a tick appears beside it, but when I select another, the tick on the previous one remains, and a new tick is added on the current cell. so two cells are ticked, but only one at a time must be ticked!!

I tried this, but it does not work:

if (cell.selected = YES) {

[cell setSelected:NO animated:YES];
[cell setAccessoryType:UITableViewCellAccessoryNone];

}else if(cell.selected = NO){

    [cell setSelected: YES animated:YES];
    [cell setAccessoryType:UITableViewCellAccessoryCheckmark];
    }

Answer 1

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

int newRow = [indexPath row];
int oldRow = [lastIndexPath row];

if (newRow != oldRow)
{
        UITableViewCell *newCell = [tableView cellForRowAtIndexPath:
                                                                indexPath];
        newCell.accessoryType = UITableViewCellAccessoryCheckmark;

        UITableViewCell *oldCell = [tableView cellForRowAtIndexPath:
                                                                lastIndexPath];
        oldCell.accessoryType = UITableViewCellAccessoryNone;

        lastIndexPath = indexPath;
}

[tableView deselectRowAtIndexPath:indexPath animated:YES];
}

OR

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

    if (cell.accessoryType == UITableViewCellAccessoryNone) {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;

    } else {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
}
