问题描述

这是我第一次使用核心数据，我收到以下错误。

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

如果你能告诉我如何解决它，我会非常感激。

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

推荐答案

这是原因：

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

1. 您创建了一些具有某些属性的实体，并写了一些代码


2. 启动了应用，可能已添加了一些内容


3. 退出应用程序并添加/更改了一些具有属性的实体


4. 您可能已经重新启动了应用程序，错误

1. You created some entities with some attributes and wrote some code
2. Launched the app, probably added some content
3. Quit the app and added/changed some more entities with attributes
4. You probably launched the app again and now it's giving you the error

这是因为您的新托管对象模型尝试使用旧版本的存储

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).

快速和脏的修复将删除存储文件（〜/ Library / Application Support / YOUR_APP /中的某处），并启动您的

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.

以后参考 - 如果您发布了应用程序，在下一个版本中，应用程序已更改了管理对象模型 - 您必须为其编写迁移。所有这些和更多的内容在核心数据编程菜谱在苹果文档中。

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.
