【讨论】：
for flag == NO 条件不工作 是的，但是对于 if(flag == NO) 条件它不起作用 当我只显示从服务器获取的正常数据时，它怎么会是我的问题，但是当我根据条件进行排序时，它会重叠（如果条件代码相同，你可以看到两者） aaray数据发送不同） 不，它无法评论该代码【参考方案2】：tableView dequeueReusableCellWithIdentifier: 表示您正在请求特定类型（标识符）的 UITableViewCell 对象，根据是否已创建具有您的标识符的单元格，您将获得一个新的或旧的对象。
您的代码请求一组表格单元格并用 UILabel 填充它们。当您滚动时，您的表格视图会请求更多表格单元格。此时，由于已经创建了一些这种类型的单元格，您将获取旧对象 - 已在其中包含 UILabel 的旧表格单元格 - 然后在这些单元格中创建 更多 UILabel。这就是它们重叠的原因。
您可以停止使用可重复使用的单元格，而只需为每个表格单元格创建一个新的 UITableViewCell，但不建议这样做。随着表格单元数量的增加，这种方法将使用更多的内存，这是可重用单元旨在克服的问题。 this answer 有更详细的解释。
相反，您应该做的只是清除您检索到的可重用单元格中的所有内容，确保您的单元格在您再次创建 UILabel 时清除任何以前创建的内容。将以下代码添加到您的 cellForRowAtIndexPath （在您检索到可重用单元格之后）方法将起到作用：
for(UIView *view in [cell subviews])
[view removeFromSuperview];

这对您有帮助吗？ 我试过了，但问题没有解决 @naresh，我更新了我的代码。重试这个。在 for 循环中更改v 而不是 vin。
我已经改了但是还是不行
@naresh，将您的代码粘贴到 pastebin.com以上是关于重叠表格单元格内容[关闭]的主要内容，如果未能解决你的问题，请参考以下文章
UITableView“dequeueReusableCellWithIdentifier”导致基于单元格内容的动态单元格高度的单元格重叠？
Excel单元格内容包含指定单元格内容时，如何把“指定单元格2”复制到“单元格1”后面？
