ios – 表视图单元重新加载第一个单元格内容

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

    CellNewsInfo *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
    if (!cell) {

        cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reusEIDentifier:@"cell"];
    }
    // Set up the cell
    int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];
    NSString *titleArticle=[[stories objectATindex: storyIndex] objectForKey: @"title"];
  titleArticle = [titleArticle StringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

    if (indexPath.row==0) {
        scr=[[UIScrollView alloc] initWithFrame:CGRectMake(0,320,200)];
        scr.tag = 1;
        scr.autoresizingMask=UIViewAutoresizingNone;
        [cell addSubview:scr];
        [self setupScrollView:scr];
        UIPageControl *pgCtr = [[UIPageControl alloc] initWithFrame:CGRectMake(120,170,80,36)];
        [pgCtr setTag:12];
        pgCtr.BACkgroundColor = [UIColor clearColor];
        pgCtr.numberOfPages=5;
        pgCtr.TintColor=[UIColor redColor];
        pgCtr.pageInDicatorTintColor=[UIColor blueColor];
        self.pageControl.hidden=YES;
        pgCtr.currentPageInDicatorTintColor = [UIColor redColor];
        pgCtr.autoresizingMask=UIViewAutoresizingNone;
        [cell addSubview:pgCtr];
    }
    else{
    cell.title.text=titleArticle;
    cell.title.numberOfLines=2;

为什么当我滚动它时,第一个单元格正在重新加载？我只想在初学者那里只有一次滚动视图.

解决方法

CellNewsInfo *cell;
if (indexPath.row == 0) {
    cell = [tableView dequeueReusableCellWithIdentifier:@"scrollCell" forIndexPath:indexPath];

    if ([cell viewWithTag:1]) {
        scr = [cell viewWithTag:1];
    }
    else {
        scr=[[UIScrollView alloc] initWithFrame:CGRectMake(0,200)];
        scr.tag = 1;
    }
    // conTinue customization here with scrollview
}
else {
    cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];
    // conTinue customization here without scroll view
}

return cell;
