Objective c 当滚动UITableView时，它与iOS名称重叠

当我滚动时，tableview提供了这种类型的重叠

我在CellForRow AtIndexPath方法中编写以下代码，我以编程方式创建tableview

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = @"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
    cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
    cell.selectionStyle = UITableViewCellSelectionStyleNone;
}

NSDictionary *info = [ASSETHELPER getGroupInfo:_groupArray[indexPath.row]];
UIImageView *view;

if (indexPath.row % 2) {
    view=[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"dark_bg"]];
}else{
    view=[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"light_bg"]];
}
cell.backgroundView=view;

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 50, 50)];
imgView.backgroundColor=[UIColor clearColor];
[imgView.layer setCornerRadius:25];
[imgView.layer setMasksToBounds:YES];
[imgView.layer setBorderColor:[UIColor whiteColor].CGColor];
[imgView setImage:[info objectForKey:@"thumbnail"]];
[cell.contentView addSubview:imgView];

UILabel *label=[[UILabel alloc]initWithFrame:CGRectMake(80, 20, 200, 30)];

[label setText:[info objectForKey:@"name"]];
[cell.contentView addSubview:label];

return cell;

}

请尝试此代码。您已使用dequeueReusableCellWithIdentifier:

NSString *CellIdentifier = [NSString stringWithFormat:@"Cell %d",indexPath.row];

UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];

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

我们不是巫师或通灵者。添加一些代码和更多详细信息。您尚未正确处理单元格的可重用性。在这里发布你的CellPathForRowatineXpath代码。好多了。对不起，如果我以前听起来很粗鲁。这里的问题是

[cell.contentView addSubview:label]。每次调用
cellforrowatinexpath:
时，您每次都在添加一个新标签。由于单元格被重复使用，以前添加的标签将永远不会删除。请检查并告知您。检查我的个人资料，您将获得我的邮件id。请帮助我将视频保存到自定义相册中。创建单元格后只需添加此代码。我想这会对你有帮助。for（UIImageView*v在[cell.contentView子视图]中）{[v removeFromSuperview]；NSLog（@“%@hello\n\n\n%@”，v[cell.contentView子视图]；}for（UILabel*v在[cell.contentView子视图]中）{[v removeFromSuperview]；NSLog（@“%@hello\n\n\n\n\n%@”，v，[cell.contentView子视图]；}您知道正确设置代码格式不是一门科学。你们给出的每一个答案我都做了，但现在我要投反对票。一旦您正确设置了答案的格式，使其可读，我将删除-1
You can try with it. Just remove the previous contentView after create a table cell.
