iOS Magical Record& SQLCipher

问题描述

我使用魔法记录来保存我的数据。此数据需要加密，因此我尝试将其与SQLCipher库结合使用（ ）。

我已经设置了SQLCipher，并使用此示例中的EncryptedStore文件成功测试了Core Data ：

我所做的只是改变了NSPersistentStoreCoordinator是这样的：

NSPersistentStoreCoordinator * coordinator = [EncryptedStore makeStore：[self managedObjectModel]：[SSKeychain passwordForService：myservice account：myaccount]];

所以我想我需要改变在MagicalRecord中创建NSPersistentStoreCoordinator的方式，但我没有运气，所以任何帮助都会受到赞赏。

解决方案

如果您已经拥有持久性存储协调器，则必须在使用MagicalRecord时手动设置核心数据堆栈。我建议这些内容：

  NSPersistentStoreCoordinator * coordinator = //你怎么做的; 
 [NSPersistentStoreCoordinator MR_setDefaultCoordinator：coordinator]; 
 [NSManagedObjectContext MR_initializeDefaultContextWithCoordinator：coordinator]; 
  

您可能需要自己公开initialize方法。

作为旁注，您可能希望在MagicalRecord问题日志中添加一个票证，以便为setup方法集合添加一个方法来指定您自己的协调器，以便MagicalRecord本身处理这项工作。 / p>

I m using Magical Record for saving my data. This data needs encryption, so i m trying to combine it with SQLCipher library(http://sqlcipher.net/ios-tutorial/).

I already setup SQLCipher and tested it with Core Data successfully, using EncryptedStore file from this example https://github.com/project-imas/encrypted-core-data:

What i did was only changed NSPersistentStoreCoordinator like this:

NSPersistentStoreCoordinator *coordinator = [EncryptedStore makeStore:[self managedObjectModel]:[SSKeychain passwordForService:myservice account:myaccount]];

So i think i need to change how NSPersistentStoreCoordinator is created in MagicalRecord, but i had no luck with it, so any help would be appreciated.

解决方案

If you already have a persistent store coordinator, you will have to setup the core data stack manually when using MagicalRecord. I recommend something along these lines:

 NSPersistentStoreCoordinator *coordinator = //how ever you do it;
 [NSPersistentStoreCoordinator MR_setDefaultCoordinator:coordinator];
 [NSManagedObjectContext MR_initializeDefaultContextWithCoordinator:coordinator];

You may need to expose the initialize method on your own.

As a side note, you may want to add a ticket to the MagicalRecord issues log to add a method to the setup method collection to specify your own coordinator so that this work is taken care of by MagicalRecord itself.
