重新添加xcdatamodel到构建设置 [英] Re-add the xcdatamodel to the Build Settings

问题描述

在我忙于尝试此问题，我不小心删除了xcdatamodel包。

我发现最近有这个问题，其中提到以下内容：

由于某些原因，xdatamodel从构建设置中删除。我添加了它，它工作。

我试着做他做的，但我不知道在哪里

我重新创建了包，但是当我尝试设置属性值时，我得到 + entityForName：找不到名为EN ...

我知道的只有;它的确有效，直到我开始愚弄与不教程的属性和东西。

解决方案

其他问题是，当你添加一个文件到项目，它不一定添加到当前目标。您可以在一个项目中有多个目标，并且可以添加未编译的文件（例如开发人员文档），因此可以添加一个文件，但是只能坐在那里而不能构建。

如果您在Xcode中选择文件并打开右侧的实用程序窗格，则会显示一个显示目标成员资格的部分。它看起来像这样：

这表明文件属于项目 momdecTests ，但不是项目 momdec 。请确保您在此处选中了您的应用目标。

While I was busy trying out stuff for this question, I accidently removed the xcdatamodel-package.

I found out that recently there was this question which mentioned the following:

For some reason, the xdatamodel was removed from the build settings. I added it back in and it worked.

I tried doing what he did, but I don't know where to start.

I recreated the package, but when I try to set an attribute value, I get +entityForName: could not locate an entity named 'EN'...

All I know is; it did work until I started fooling around with not-tutorial-attributes and stuff.

解决方案

What they're getting at in that other question is that when you add a file to a project, it's not necessarily added to the current target. You can have multiple targets in a project, and you can add files that don't get compiled (e.g. developer documentation), so it's possible to add a file but then have it just sit there and not get built.

If you select the file in Xcode and open up the Utilities pane on the right, there's a section that shows target membership. It looks like this:

This one shows that the file belongs to the project momdecTests but not to the project momdec. Make sure your app target is checked here.
