如何启用“使用核心数据"在现有项目上? [英] How to enable "Use Core Data" on existing project?

问题描述

在创建我的项目之前，我不确定是否要使用 Core Data.我想这是我以后可以轻松打开/关闭的东西.我开始后悔我没有立即决定的决定.

Before creating my project, I wasn't sure if I was going to use Core Data. I figured it'd be something I can easily toggle on/off later. I'm starting to regret my decision of not deciding immediately.

有什么办法可以打开它吗?还是我必须创建一个完全独立的项目才能启用它?

Is there any way I can turn it on? Or do I have to create an entirely separate project just to enable it?

推荐答案

转到 XCode 菜单并单击 File -> New -> File.然后向下滚动到核心数据并添加数据模型.从那以后，恐怕您将不得不研究如何从该数据模型中添加、编辑和删除数据.

Got to XCode menu and click File -> New -> File. Then scroll down to Core Data and add Data Model. From there I'm afraid you are going to have to study up on how to add, edit, and delete data from that Data Model.
