推荐答案

我不同意你必须开始一个新项目.将 CoreData 集成到现有项目中实际上非常容易——一个好的起点是创建一个新的 CoreData 项目，但将它生成的代码复制到现有项目中(仔细检查应用程序委托，看看它设置了什么).真正涉及的代码并不多，而且很容易创建新的数据模型.

I disagree that you have to start a new project. It's actually pretty easy to integrate CoreData into an existing project - a good starting point is to create a new CoreData project, but copy the code it generates into your existing project (examine carefully the app delegate to see what it sets up). There's really not that much code involved, and it's easy to create new data models.

通过 Apple 的 CoreData 教程来了解正在发生的事情也是一个非常好的主意，而且还有一些好书.

It's also a really good idea to work through Apple's CoreData tutorials to understand what is going on, and there are some good books as well.
