iPhone的Core Data入门？ [英] Getting started in Core Data for iPhone?

问题描述

我想在我的iPhone应用程序中实现Core Data。那么，什么是最好的方式来学习Core数据专门为iPhone？我有4小时的时间，我可以投入今天，所以理想情况下，我会有足够的能力将这（但稍微）添加到我的应用程序。

I want to implement Core Data into my iPhone app. So what is the best way to learn Core Data specifically for the iPhone? I have 4ish hours that i can devote to this today, so ideally I would be competent enough to add this (however slightly) into my app.

数据现在是通过NSUserDefaults，只是这样，当应用程序关闭和重新打开，他们的数据仍然存在。

The only way i retain data now is through NSUserDefaults, just so that when the app is closed and reopened, their data is still there. I want to give the user the ability to save sets of data, read them, edit them, delete them, etc.

没有，严重的，它可能看起来像明显的建议，但单页文档提出了一个不错的策略，文档和教程阅读，订购。一旦你完成了第一个教程，它建议，奇怪的术语会感觉很少奇怪。

No, seriously, it might seem like obvious advice, but that one-page document lays out a nice strategy for which documents and tutorials to read and in which order. Once you work through the first tutorial it recommends, the weird terminology will feel a lot less weird.
