我正在使用MagicalRecord与sqlite,当我启动MagicalRecord,我用
[MagicalRecord setupCoreDataStackWithStoreNamed:@"OrderSystem.sqlite"];
并产生以下消息：
2012-10-16 16:54:48.966 OrderSystem[4135:c07] +NSManagedObjectContext(MagicalRecord) MR_contextWithStoreCoordinator: -> Created : Context * MAIN THREAD *
当我尝试使用后台线程存储我的实体与以下代码：
[MagicalRecord saveInBackgroundWithBlock:^(NSManagedObjectContext *localContext){
Menu *localMenu = [menu inContext:localContext];
localMenu.name = menu.name;
localMenu.menuid = menu.menuid ;
}];
我收到以下错误消息：
2012-10-16 17:05:20.118 OrderSystem[4523:4603] +MagicalRecord(ErrorHandling) defaultErrorHandler: Error Message: The operation couldn’t be completed. (Cocoa error 133000.)

当我使用findAll检查我存储的数据实体时,它似乎存储在数据库中.如果我完全关闭应用程序,并重新启动应用程序,那么实体仍然存在(这表明实体已经被持久存储,而不仅仅是在内存中).所以似乎一切都正常,但是任何想法是什么错误信息？有什么办法把它们关掉吗？还是解决他们？因为它阻止我的其他NSLog …
谢谢
