Iphone uitableview分区有问题-每个分区中的单元格都在重复

提前感谢您的帮助，我很难理解代码。我试图将一个运行良好的现有uitable分为4个部分。正如您所看到的，我有4个部分，每个部分中有不同数量的行和每个部分的名称。编译时，节正确地存在，但单元格重复。我尝试过其他帖子中关于这个主题的各种方法，也尝试过谷歌搜索的信息，但我不断收到大量错误。如果有人能告诉我我遗漏了什么，我将不胜感激！谢谢

// Return the number of sections.
return 4;

        return 2;

您必须添加一个

switch (indexPath.section)

在cellForRowAtIndexPath中

或者一个if-else子句

大概是这样的：

if (indexPath.section == 0 && indexPath.row == 0)
{
     // for the first row in the first section
}
else if (indexPath.section == 3 && indexPath.row == 2)
{
    // for the 4 section and 3 row
}

switch (indexPath.section)

if (indexPath.section == 0 && indexPath.row == 0)

{
    // for the 4 section and 3 row
}
