核心数据; 可可错误134100

Question

这是我第一次使用核心数据,我收到以下错误.

如果你能告诉我如何解决它,我将非常感激.

Answer 1

原因如下:

用于打开商店的模型与用于创建商店的模型不兼容

这是你如何做到的:

1. 您创建了一些具有某些属性的实体并编写了一些代码
2. 推出应用程序,可能添加了一些内容
3. 退出应用程序并添加/更改了一些具有属性的实体
4. 你可能再次启动了应用程序,现在它给你错误

原因是因为您的新托管对象模型正在尝试使用旧版本的存储(第一次在您启动应用时创建).

快速而又脏的修复方法是删除存储文件(〜/ Library/Application Support/YOUR_APP /中的某个位置)并再次启动应用程序.

供将来参考 - 如果您发布应用程序,并且在下一版本中应用程序已更改托管对象模型 - 您必须为其编写迁移.苹果文档中的核心数据编程手册涵盖了所有这些以及更多内容.

Answer 2

如果您从模拟器/设备中删除应用程序就足够了.

您不必更改项目中的文件(除了选择当前模型并使用菜单替换类:编辑器/创建NSManaged Object子类).
