UIManagedDocument示例/教程 [英] UIManagedDocument example / tutorial

问题描述

我一直在努力创建一个简单的 UIManagedDocument 库样式应用程序（保存到iCloud的单独文档）。

I have been trying very unsuccessfully to create a simple UIManagedDocument library style application (separate documents saved to iCloud).

我对以下内容感到困惑：

I am confused with the following:

我是否继承 UIManagedDocument 并设置 persistentStoreCoordinator ， ManagedObjectModel &这个子类中的 ManagedObjectContext ，或者这些应该是在 AppDelegate 中配置的（如果是的话，我该如何去关于刷新 persistentStoreCoordinator 来查看新文件 - 似乎一旦读过 persistentStore 我就可以'得到它读取一个新的持久性商店）？

Do I subclass UIManagedDocument and set up the persistentStoreCoordinator, ManagedObjectModel & ManagedObjectContext within this subclass, or are these supposed to be configured within the AppDelegate (and if so, how do I go about refreshing the persistentStoreCoordinator to look at the new file - it seems that once that has read a persistentStore that I can't get it to read a new persistent store)?
