在保存Core Data之前，销毁它

问题描述

如果我在Core Date（使用Magical Record）中创建一个新的自定义对象，如

If I create a new Custom Object in Core Date (using Magical Record) like so

List *list = [List MR_createInContext:_managedObjectContext];

然后我对它执行各种操作，例如设置其名称

And then I perform various actions on it, such as setting its name

list.name = @"Foobar List";

但是用户决定取消创建此列表，我需要删除吗？就像在里面，这个列表已经在内存中，即使我没有保存本地上下文与 [localContext MR_save];

But then the user decides to cancel the creation of this list, do I need to delete? As in, is this list already in memory even though I haven't saved the local context with [localContext MR_save];

推荐答案

如果在受管对象上下文中创建对象，它将在下次保存更改时保存。如果您不想保存，您必须将其删除。

If you create the object in the managed object context, it will get saved the next time you save changes. If you don't want to save it, you'll have to delete it.
