RestKit 多个 RKObjectManagers 对象映射 [英] RestKit multiple RKObjectManagers object mapping

问题描述

我使用了两个 RKObjectManager，一个没有 RKManagedObjectStore(这是共享实例)，另一个有.当我尝试像这样设置 RKManagedObjectStore 时:

I'm using two RKObjectManagers, one without an RKManagedObjectStore, (which is the shared instance) and one with. When I attempt to set the RKManagedObjectStore like so:

[self.storeBackedObjectManager setObjectStore:[RKManagedObjectStore objectStoreWithStoreFilename:@"conversations.sqlite"]];

我收到以下错误:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '[RKObjectManager sharedManager].objectStore cannot be nil'

似乎 RestKit 正在尝试访问 NSManagedObject+ActiveRecord.m 中的 sharedManager(它不使用对象存储)的对象存储:

It seems that RestKit is trying to access the objectstore of the sharedManager (which doesn't use an object store), in NSManagedObject+ActiveRecord.m:

+ (NSManagedObjectContext*)managedObjectContext {
NSAssert([RKObjectManager sharedManager], @"[RKObjectManager sharedManager] cannot be nil");
NSAssert([RKObjectManager sharedManager].objectStore, @"[RKObjectManager sharedManager].objectStore cannot be nil");
return [[[RKObjectManager sharedManager] objectStore] managedObjectContext];

}

有什么方法可以将引用传递给我的第二个存储支持的 RKObjectManager 实例?(如果我临时将共享管理器设置为商店支持的实例，则此映射工作正常)

Is there any way to pass a reference to my second, store backed RKObjectManager instance? (This mapping works fine if I temporarily set the shared manager to the store backed instance)

推荐答案

您正尝试将共享的 RKObjectManager 用于托管(核心数据)和非托管模型.您必须为该 RKObjectManager 设置 objectStore 属性.

You are trying to use a shared RKObjectManager for managed (coredata) and unmanaged models. You have to set objectStore property for that RKObjectManager.

我认为您可以单独使用两个 RKObjectManager，只需使用 initWithBaseURL

I think you can use two RKObjectManagers separately, just create them using initWithBaseURL
