ItemsViewController.m中的重複問題

Question

即使我沒有改變相關方法中的任何內容，我也會在ItemsViewController.m中重複出現問題。在此之前，我曾詢問過一些問題，然後糾正了它們，但它們再次出現。沒有對正在大吵大鬧的方法/領域做出任何改變。已經評論了問題領域。

有沒有編譯器問題？

這是文件;提前致謝。

這行看起來失蹤到底塊：

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

應該是：

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