  1. POUse MagicalRecord with another existing context in RestKit
    text
    copied!<p>I want to keep using my current RestKit while use MagicRecord for rest of fetches and updates. I want Restkit's MOC send updates to MagicRecord's default context. If I understand right, this is what I am doing. Is this ok?</p> <pre><code>NSManagedObjectContext* context = [[RKObjectManager sharedManager].objectStore managedObjectContextForCurrentThread]; [MagicalRecord setupCoreDataStackWithAutoMigratingSqliteStoreNamed:[XDBStore storeName]]; [context setParentContext:[NSManagedObjectContext MR_defaultContext]]; </code></pre> <p>Maybe another way to do it, but still not sure.</p> <pre><code>NSPersistentStoreCoordinator *coordinator = [[[RKObjectManager sharedManager] objectStore] persistentStoreCoordinator]; [NSPersistentStoreCoordinator MR_setDefaultStoreCoordinator:coordinator]; [NSManagedObjectContext MR_initializeDefaultContextWithCoordinator:coordinator]; </code></pre> <p>Anyone had same issue before?</p> <p><strong>EDIT 1</strong></p> <p>I tried the @casademora's suggestion #1 to set default context, but got this error.</p> <pre><code>*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Can only use -performBlockAndWait: on an NSManagedObjectContext that was created with a queue.' </code></pre> <p><strong>EDIT 2</strong></p> <p>I found a hack. First, open up the setter for default context at magicalrecord. Next, change the concurrency type for RestKit store so its context can be used at magicalrecord.</p> <p><strong>NSManagedObjectContext+MagicalRecord.h</strong></p> <pre><code>+ (void) MR_setDefaultContext:(NSManagedObjectContext *)moc; + (void) MR_setRootSavingContext:(NSManagedObjectContext *)context; </code></pre> <p><strong>RKManagedObjectStore.m</strong></p> <pre><code>NSManagedObjectContext *managedObjectContext = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSMainQueueConcurrencyType]; </code></pre> <p><strong>Then setup MagicalRecord like this:</strong></p> <pre><code>NSManagedObjectContext* context = [[RKObjectManager sharedManager].objectStore managedObjectContextForCurrentThread]; [NSManagedObjectContext MR_setRootSavingContext:context]; NSManagedObjectContext *defaultContext = [NSManagedObjectContext MR_newMainQueueContext]; [defaultContext setParentContext:context]; [NSManagedObjectContext MR_setDefaultContext:defaultContext]; </code></pre>
