在此先感谢您的帮助,但是我在将代码包起来时遇到了麻烦。我正在尝试将效果很好的现有uitable分为4个部分。如您所见,我有4个部分,每个部分的行数各不相同,每个部分的名称也不同。编译时,各节正确放置,但重复单元格。我已经尝试了关于该主题的其他帖子以及Google信息中的各种方法,但是我不断收到很多错误。如果有人可以告诉我我遗漏的内容,我将不胜感激!谢谢。

最佳答案

您必须添加一个

switch (indexPath.section)


在cellForRowAtIndexPath中。

或if-else子句。

像这样的东西:

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
}
