Objective c ItemsViewController.m中重复出现的问题

我在ItemsViewController.m中遇到了重复的问题，尽管我没有更改相关方法中的任何内容。之前有一些问题，我问了这么早，然后纠正了他们，但他们又出现了。没有对方法/区域进行任何更改，这再次引起了骚动。我们已经评论出了问题的领域

可能有编译器问题吗

这是文件；提前谢谢

此行似乎缺少块的结尾：

[detailViewController setDismissBlock:^{[[self tableView]reloadData];

应该是：

[detailViewController setDismissBlock:^{[[self tableView]reloadData]}];
