Xcode 4 数据模型版本控制错误？

[英]Xcode 4 Data Model Versioning bug?

原文 2011-03-16 20:20:43 7 3 core-data/ xcode4

Installed Xcode 4 and it all seems fine... except, when I try to add versioning to a Core Data model.安装了 Xcode 4，一切看起来都很好……除了，当我尝试将版本控制添加到 Core Data 模型时。 In the instructions it says I should select the data model in the navigator and then "Choose Editor > Convert to Versioned Model."在说明中，它说我应该在导航器中选择数据模型，然后“选择编辑器 > 转换为版本化模型”。 Well, the "Editor" menu does not have an item "Convert to Versioned Model"!!!好吧，“编辑器”菜单没有“转换为版本模型”项！！！ Skipping this step crashes Xcode 4. Also, I can't believe that there is no support for Xcode 4 now that it is a pay product!跳过这一步会导致 Xcode 4 崩溃。此外，我不敢相信 Xcode 4 现在是付费产品，因此不支持它！

3 个解决方案

There are currently several issues with the core data model editor in Xcode 4. I highly recommend installing Xcode 3 next to Xcode 4 and doing all of your model work in Xcode 3 until these issues are addressed.目前 Xcode 4 中的核心数据模型编辑器存在几个问题。我强烈建议在 Xcode 4 旁边安装 Xcode 3，并在 Xcode 3 中完成所有模型工作，直到这些问题得到解决。

I also recommend filing a feedback so that you can add your voice to this issue.我还建议提交反馈，以便您可以对此问题发表意见。

First select your xcdatamodeld file and go to the Editor Menu and select the Add Model Version option.首先选择您的 xcdatamodeld 文件并转到编辑器菜单并选择添加模型版本选项。 After you create your new version select again the xcdatamodeld file and be sure you have the Utilities sidebar shown and select the first icon, the File Inspector one.创建新版本后，再次选择 xcdatamodeld 文件并确保显示实用工具侧栏并选择第一个图标，即文件检查器。 You will have a Versioned Data Model option.您将有一个版本化数据模型选项。

Hope that was what you were looking for.希望这就是你要找的。

I had the same issue with xcode 4.5.我在 xcode 4.5 上遇到了同样的问题。 And after some time I have resolved it:一段时间后，我解决了它：

Move my test.xcdatamodel file to the root in the project navigator.将我的 test.xcdatamodel 文件移动到项目导航器中的根目录。
Highlight file in a new location and select Editor -> Add Model Version...在新位置突出显示文件并选择编辑器 -> 添加模型版本...

And xcode automatically creates *.xcdatamodeld with two files : 'test 2.xcdatamodel' and 'test.xcdatamodel'.并且 xcode 自动创建带有两个文件的 *.xcdatamodeld：'test 2.xcdatamodel' 和 'test.xcdatamodel'。 And 'test 2.xcdatamodel' is marked as current version.并且“test 2.xcdatamodel”被标记为当前版本。
