Adding core data to my iPhone app
提问by mslot
I have been here before, asking for a mapping library that could store objects in a database. Some one told me about the Core Data Framework. I have read a bit about it and I kindda understand it. I have created some "test Core data projects", where I have worked with simple problems and models ala Person and Group. But now I want to experiment with implementing Core Data to one of my small iPhone apps. How do I do this? Subclassing from NSManagedObject and make a Managed Object Model? I know that there is more to it, but I havent found anything on google og apples site. Maybe Im looking in wrong direction while googling and searching. A link to an article/tutorial explaining me how to add Core Data to my project would make my day.
我以前来过这里，要求一个可以在数据库中存储对象的映射库。有人告诉我关于核心数据框架。我已经阅读了一些关于它的内容，我有点理解它。我创建了一些“测试核心数据项目”，在那里我处理了简单的问题和模型 ala Person 和 Group。但现在我想尝试将 Core Data 实施到我的一个小型 iPhone 应用程序中。我该怎么做呢？从 NSManagedObject 子类化并创建托管对象模型？我知道还有更多内容，但我没有在 google og apples 网站上找到任何内容。也许我在谷歌搜索和搜索时看错了方向。一个解释我如何将 Core Data 添加到我的项目的文章/教程的链接会让我开心。

There's a tutorial on iPhone developer site here. And there are several sample codeswith Core Data as well. These should get you started.

The book, More iPhone 3 Developmentbegins with a great tutorial demonstrating how to use Core Data. I've found it incredibly helpful.

Here is a basic CoreData screencastthat, while not specifically for the iPhone gives a decent introduction to CoreData concepts.
这是一个基本的CoreData 截屏视频，虽然不是专门针对 iPhone 的，但它很好地介绍了 CoreData 概念。
