Ios UITableView删除/添加行导致CoreData：如果在SplitViewController的主视图中选择了另一个对象，则会出现严重的应用程序错误
更新18/3#2。我已经开始计算开始更新和结束更新，以确保它们相等。在出现异常之前，它们就不同步了。不知道为什么。 更新18/3：我想我已经发现了问题，但我不确定我是否知道如何解决它。经过几个小时的实验，我发现只有在会话期间在svc的主表视图中选择了多个项目时，我才能使应用程序崩溃。 在主表视图中选择另一项时，详图表视图将获得一个新的对象集，并调用refreshtables，即使它处于更新/移动/删除/插入周期的中途。因此，问题就出现了；我认为它有更新旧故事对象的指令，即使在detailviewcontroller上设置了新故事对象 在细节视图中设置新故事之前，如何使动画/coredata/tableview更新得到完全处理？当SetEditing==否时，我将更改保存到managedObjectContext。我想我需要制作一个自定义SetTory setter，在接受新对象之前处理对UITableView/CoreData集的所有更新？ 此代码在didSelectRowAtIndexPath中的svc主tableview控制器上调用：Ios UITableView删除/添加行导致CoreData：如果在SplitViewController的主视图中选择了另一个对象，则会出现严重的应用程序错误,ios,cocoa-touch,ipad,uitableview,core-data,Ios,Cocoa Touch,Ipad,Uitableview,Core Data,更新18/3#2。我已经开始计算开始更新和结束更新，以确保它们相等。在出现异常之前，它们就不同步了。不知道为什么。 更新18/3：我想我已经发现了问题，但我不确定我是否知道如何解决它。经过几个小时的实验，我发现只有在会话期间在svc的主表视图中选择了多个项目时，我才能使应用程序崩溃。 在主表视图中选择另一项时，详图表视图将获得一个新的对象集，并调用refreshtables，即使它处于更新/移动/删除/插入周期的中途。因此，问题就出现了；我认为它有更新旧故事对象的指令，即使在detailview

- 16/3我试图真正简化我的代码。我已经删除了对托管对象上下文的所有调用，并将它们放在setEditing中，删除了多余的[self.tableview reloadData]和[self.tableview setneedsdisplay]并完全使“reordering”bool无效（它仍在代码中，但它总是设置为NO，因此没有区别）。UITableView比以往任何时候都更稳定，但我仍然设法在删除时（偶尔在添加时）出现间歇性错误—崩溃似乎需要一段时间，但仍然会**
- 15/3：我认为这与CoreData/UITableView不同步有关——CoreData认为它比UITableView少或多
- CoreData集没有问题，它只是事物的动画/UI方面（事物被移除）
- 它是断断续续的，只是在某些情况下
- 在railwayparade的帮助下，我在didChangeObject中实现了NSFetchedResultsChangeMove：它修复了移动错误，但没有修复删除错误
