“无法找到源存储的模型”发生在iphone“自动轻量级迁移”？ [英] "Can't find model for source store" occurring during iphone "Automatic Lightweight Migration"?

问题描述

我真的卡在这里与升级测试从v1到v2的iPhone应用程序。我有IPA版本，我正在通过iTunes通过我的iPhone设备，一个为v1的应用程序和一个v2的ad hoc分发测试。请注意：

I'm really stuck here with upgrade testing from v1 to v2 of an iPhone application. I have IPA releases that I'm testing via ad hoc distribution via iTunes to my iPhone device, one for v1 of the app and one for v2. Note that:

• 如果我删除v1和部署v2，则


• （因此没有迁移），那么它工作正常


• 当我部署v2，而v1已经在那里我得到的错误：原因=无法找到源存储模型

问题 - 任何想法如何解决这个问题？我可以在这里进行什么调试/分析？如果您需要更多信息，请告诉我。

Question - Any ideas how to resolve this? What debugging/analysis could I do here? Let me know if you need any more info.

我所做的概述是：



• 将我的v1应用程序部署到AppStore，而没有为我的核心数据模型设置一个版本（即在版本时没有真正意识到，因此没有设置）


• 对于v2，唯一的额外更改是一个模型上的一个新属性


• 所以对于v2版本，我所做的是：


• 重建了新的Core Data模型


• 为模型创建了v1版本


• 创建了v1的对象/属性


• 已保存


• 为模型创建了v2版本


• 创建了一个附加属性


• 已保存


• 已重新构建管理对象类


• 更新了代码以将http://developer.apple.com/library/mac/ ＃documentation / Cocoa / Conceptual / CoreDataVersioning / Articles / vmLightweight.html＃// apple_ref / doc / uid / TP40008426-SW1 调用addPersistentStoreWithType时


• Deployed my v1 app to the AppStore without setting up a version for my core data model (i.e. wasn't really aware at the time of versions, so didn't set one up)
• The only additional change for v2 was one new attribute on the one model
• So for the v2 release what I've done is:
• Recreated a new Core Data Model
• Created a v1 version for the model
• Created the object/attributes for v1
• Saved
• Created a v2 version for the model
• Created the one additional attribute
• Saved
• Recreated the managed object classes
• Updated the code to put the options in per http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CoreDataVersioning/Articles/vmLightweight.html#//apple_ref/doc/uid/TP40008426-SW1 when calling addPersistentStoreWithType

编辑：另一个不清楚的问题，通过审阅下面提供的链接jrturton ：

Another question that is not clear to me, as raised by reviewing the link jrturton provided below is:



1. 现在最新的XCode版本如何将设置当前版本设置为相应的型号版本文件？即前面的帖子突出显示了两个不同的步骤，一个添加模型版本，然后单独设置当前版本


2. 如何使用核心数据模型标识符字段，为每个核心数据模型文件设置。它在检查员。该参数存在于例如MyApp 1.xcdatamodel，MyApp 2.xcdatamodel和MyApp.xcdatamodel文件中，因此您需要在每个文件中放置什么？






推荐答案

当选择xcdatamodeld文件时，在实用程序检查器（右侧窗格）的标识和类型选项卡下设置数据模型的版本。这有一个名为核心数据模型的部分和一个名为标识符的字段。

You set the version of your data model in the Utilities inspector (right hand pane), under the Identity and Type tab when the xcdatamodeld file is selected. This has a section called "Core Data Model", and a field called "Identifier".

您通过选择xcdatamodeld文件添加一个新的模型版本， - >添加模型版本。

You add a new model version by selecting the xcdatamodeld file, the going to Editor --> Add model version.

此时，它会提示您先前的模型基于它。

At this point it prompts you for the previous model to base it on.

如果您未经过此过程添加了新模型，轻量级迁移可能无法正常工作。

If youve added a new model without going through this process the lightweight migration may not work.
