答案 1 :(得分：0)
tableView dequeueReusableCellWithIdentifier:表示您正在请求特定类型（标识符）的UITableViewCell对象，并且您将获得新的或旧的对象，具体取决于是否已创建具有您的标识符的单元格
您的代码请求一组表格单元格并使用UILabel填充它们。滚动时，表视图会请求更多表格单元格。此时，由于已经创建了这种类型的某些单元格，因此您将获得旧对象 - 已包含UILabel的旧表格单元格 - 然后在这些单元格中创建更多 UILabel。这就是他们重叠的原因。
您可以停止使用可重复使用的单元格，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，该方法将使用更多的存储器，这是可重用单元旨在克服的问题。 this answer中提供了更详细的说明。
相反，您应该做的只是清除您检索的可重用单元格中的所有内容，确保在再次创建UILabel时，您的单元格中没有任何先前创建的内容。将以下代码添加到cellForRowAtIndexPath（在检索到可重用单元格之后）方法可以解决这个问题：
for(UIView *view in [cell subviews])
[view removeFromSuperview];
