打开uiviewcontroller后出现NSObjectInaccessibleException

我正在开发一个应用程序，其中自定义tabbar打开不同的tableview . tableview的信息由JSON远程源提供 . 并使用自定义nsmanagedobject保存到Core Data中 .

在didSelectRowAtIndexPath中打开和关闭uiview后触发错误 . 详细视图在桌面视图上打开，并在角落有一个关闭按钮 . 该视图仅适用于阅读文章，不适用于编辑，重写或删除 . 打开并关闭详细视图两次后出现错误 .

该日志表示NSManagedObject已失效 . 但是，当我没有删除或更新对象时，如何 . 它发生在每个细胞行 .

我做错了什么？

其中八个，九个，十个......是在viewdidLoad中启动并在dealloc中释放的NSArrays .
