iOS，覆盖cellForRowAtIndexPath以返回自定义单元格

为了向可用于标识行的单元格添加属性，我创建了一个自定义单元格，该单元格是从UITableViewCell子类化的。该部分似乎工作正常，但是当我尝试实现didSelectRowAtIndexPath时，我无法获取自定义单元格指针，因此无法访问该属性。我是否需要覆盖cellForRowAtIndexPath？

- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *MyIdentifier = @"MyReuseIdentifier";

    NLSTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];

    if (cell == nil) {
        cell = [[NLSTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier];
    }

    NSLog(@"indexPath: %ld", indexPath.row);
    NSDictionary *cellDict = [self.sql getTitleAndIdForRow:indexPath.row];

    NSArray *keys = [cellDict allKeys];
    id rowId = [keys objectAtIndex:0];
    id title = [cellDict objectForKey:rowId];

    cell.textLabel.text = title;
    cell.rowId = (NSUInteger)rowId;
    return cell;
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];

    //This message returns a UITableViewCell, not a my custom NLSTableViewCell
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

    NSString *string = [[NSString alloc] init];
    string = cell.textLabel.text;
    NSUInteger rowId = cell.rowId;
    NSLog(@"id: %ld, title: %@", rowId, string);
}
