核心数据；可可错误 134100 [英] Core Data; Cocoa error 134100

问题描述

这是我第一次使用核心数据，出现以下错误.

This is my first time with core data, and I am getting the following error.

如果您能告诉我如何修复它，我将不胜感激.

I would really appreciate it if you could tell me how to fix it.

推荐答案

原因如下:

用于开设商店的模型与用于创建商店的模型不兼容

The model used to open the store is incompatible with the one used to create the store

这就是你是如何做到的:

And here's how you did it:

1. 您创建了一些具有一些属性的实体并编写了一些代码
2. 启动应用，可能添加了一些内容
3. 退出应用程序并添加/更改更多具有属性的实体
4. 您可能再次启动了应用程序，现在它给了您错误

这是因为您的新托管对象模型试图使用旧版本的存储(第一次在您启动应用程序时创建的).

The reason for this is because your new managed object model is trying to use older version of storage (the one first time created when you launched the app).

快速而肮脏的解决方法是删除存储文件(在 ~/Library/Application Support/YOUR_APP/中的某处)并再次启动您的应用.

The quick and dirty fix would be to remove the storage file (somewhere in ~/Library/Application Support/YOUR_APP/) and to launch your app again.

为了将来参考 - 如果您发布了一个应用程序并且在下一个版本中该应用程序已更改托管对象模型 - 您必须为其编写迁移.Apple 文档中的核心数据编程手册中涵盖了所有这些以及更多内容.

For future reference - if you release an app and in next release the app has changed managed object model - you have to write migrations for it. All this and more is covered in core data programming cookbook in apple documentation.
