MagicalRecord（CoreData）+今天扩展（iOS8）...他们玩吗？ [英] MagicalRecord (CoreData) + Today Extension (iOS8)... Will They Play?

问题描述

希望你能帮忙。我要为我的应用添加今天的支持，该应用使用MagicalRecord https://github.com/magicalpanda/MagicalRecord管理我的所有CoreData资料。

Hoping you can help. I'm adding Today support to my app, which uses MagicalRecord https://github.com/magicalpanda/MagicalRecord to managing all my CoreData stuff.

我撕掉了我的头发，试图了解如何将我的数据表达到今天的扩展。

I'm tearing my hair out trying to understand how to surface my data into the Today extension.

我已启用此处列出的应用组 http://blog.sam-oakley.co.uk/post/92323630293/sharing-core-data-between-app-and-extension-in-ios -8 然而，我正在阅读的所有文档和StackOverflow帖子涉及直接使用CoreData。 MagicalRecord为你做了很多艰苦的工作，这就是为什么我使用它，因为我是完全新的在这个项目的开始。例如：

I have enabled app groups as outlined here http://blog.sam-oakley.co.uk/post/92323630293/sharing-core-data-between-app-and-extension-in-ios-8 however all the documentation and StackOverflow posts I'm reading relate to using CoreData directly. MagicalRecord does a lot of the hard work for you, which is why I used it as I was totally new to it all at the beginning of this project. So things like:

在初始化你的Core Data栈的时候，你会在
中添加一个存储到persistStoreCoordinator像这样：

Where you initialise your Core Data stack, you’ll be adding a store to your persistentStoreCoordinator a little something like this:

[persistentStoreCoordinator
addPersistentStoreWithType:NSSQLiteStoreType configuration:nil
URL:storeURL options:options error:&error]

这只是一个问题，将storeURL
（通常是NSDocumentDirectory中的某个位置）的先前值更改为共享应用程序组文件夹中
中包含的位置。您可以使用

It’s simply a matter of changing your previous value for storeURL (usually somewhere in NSDocumentDirectory) to a location contained in your shared App Group folder. You do this using

containerURLForSecurityApplicationGroupIdentifier: NSURL *directory =
[[NSFileManager defaultManager]
containerURLForSecurityApplicationGroupIdentifier:@"group.YourGroupName"];
NSURL *storeURL = [directory 
URLByAppendingPathComponent:@"YourAppName.sqlite"];

...我不明白如何/在哪里实施。

... I'm not understanding how / where to implement.

我想象我只需要在我的扩展中设置MagicalRecord堆栈，就像在我的appDelegate中一样，但是它失败了。

I'd imagined I'd just have to set up the MagicalRecord stack in my extension as I do in my appDelegate, but of course it's failing.

真的希望有人处于类似的情况，并且能够阐明如何继续前进。

Really hoping someone might be in a similar situation and be able to shed some light on how to move forward with this one.

您需要的任何代码

提前感谢

推荐答案

更改

[MagicalRecord setupCoreDataStackWithStoreNamed:@"Database"];

到

 - (void)setupCoreDataStack
{
     if ([NSPersistentStoreCoordinator MR_defaultStoreCoordinator] != nil)
     {
        return;
    }

    NSManagedObjectModel *model = [NSManagedObjectModel MR_defaultManagedObjectModel];
    NSPersistentStoreCoordinator *psc = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:model];

    NSURL *storeURL = [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:@"group.yourgroup"];
    storeURL = [storeURL URLByAppendingPathComponent:@"Database.sqlite"];

    [psc MR_addSqliteStoreNamed:storeURL withOptions:nil];
    [NSPersistentStoreCoordinator MR_setDefaultStoreCoordinator:psc];
    [NSManagedObjectContext MR_initializeDefaultContextWithCoordinator:psc];
}
