终于大致tableview知道如何刷新了

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

{

    static NSString *cellIdentifier = @"Cell";

    BDStoryShelfCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if (!cell) {

        cell = [[BDStoryShelfCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];

        cell.backgroundColor = [UIColor clearColor];

        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        cell.delegate = self;

    }

    

    NSMutableArray *array = [[NSMutableArray alloc] init];

    

    NSInteger startIndex = indexPath.row * KeyStoryShelfBookCount;

    NSInteger step = KeyStoryShelfBookCount;

    

    for(int i = 0;i < step;i++) {

        

        NSInteger index = startIndex + i;

        

        if(index < self.bookListArray.count) {

            BDStoryBookDetailInfo *bookInfo = [self.bookListArray objectAtIndex:index];

            [array addObject:bookInfo];

        }

    }

    [cell refreshWithData:array];

    

    return cell;

}
