如何恢复丢失的CoreData Model版本？

dea*_*_au 2 core-data core-data-migration ios

所以,我搞砸了.我在Xcode中创建了一个现有CoreData模型的新版本,并且以某种方式从未最终提交.xcdatamodel文件(或更准确地说,contents文件在其中).现在,不久之后,该文件已经丢失,我无法恢复它.试图在xcode中打开xcdatamodel文件给我错误"文件"内容"因为没有这样的文件而无法打开".

我以为我可以聪明并contents从以前的版本.xcdatamodel文件中复制文件,然后只需添加我为此迁移添加的表(幸运的是我只添加了一个表并生成了一个类,因此再次创建表很容易).问题是,当我在模拟器或已存在数据的设备上运行应用程序时,我收到以下错误:Error Domain=NSCocoaErrorDomain Code=134130 "The operation couldn’t be completed. (Cocoa error 134130.)"

该错误还列出了NSPersistentStoreCoordinator的当前模型哈希,因此现在我假设所讨论的模型的哈希很可能是不同的.

我有什么选择？如何修复数据,以便用户在更新之前不必卸载应用程序并丢失所有数据？

以下是错误的完整内容:

尝试重新创建缺失版本时遇到的错误几乎可以肯定是因为您没有以完全相同的方式重新创建它.如果你不确定,最简单的方法就是再试一次.如果您创建的新组件与旧组件完全匹配,则没有理由不起作用.

如果您无法执行此操作,则可以使用以下方法从应用程序的应用程序商店副本还原模型:

如果您从一个Xcode存档(a .xcarchive)开始,那只是一个包含应用程序包和其他东西的文件包.浏览它以查找momd包含所有 Core Data模型的内容,然后在该软件包中查找mom与您的缺失版本匹配的单个内容.将该文件复制到存档之外的某个位置.

如果您从一个开头ipa,那只是一个包含该应用程序的zip文件.用你喜欢的任何解压缩工具解压缩它,然后按照上面的步骤找到正确的mom.

该mom文件是已编译的模型,但与源代码不同,模型编译可以反转.在Xcode中创建一个新的模型版本并删除它中的所有内容,使其完全为空.然后去编辑菜单,然后选择导入....导入mom上面找到的文件.

您现在应该拥有与应用程序中已编译模型完全对应的Core Data模型版本.将它提交到您的源代码存储库,以便下次可以使用它.
