I'm trying to update my existing app that was using Restkit 0.1 to 0.20 but I'm facing some problems when setting up the Core Data Stack as it runs into an exception.
I've got the following code on my AppDelegate:
/*
Complete Core Data stack initialization
*/
NSError *error = nil;
NSURL *modelURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"AppModel" ofType:@"momd"]];
// NOTE: Due to an iOS 5 bug, the managed object model returned is immutable.
NSManagedObjectModel *managedObjectModel = [[[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL] mutableCopy];
RKManagedObjectStore *managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:managedObjectModel];
[managedObjectStore createPersistentStoreCoordinator];
NSString *storePath = [RKApplicationDataDirectory() stringByAppendingPathComponent:@"TSI.sqlite"];
NSString *seedPath = [[NSBundle mainBundle] pathForResource:@"RKSeedDatabase" ofType:@"sqlite"];
//NSPersistentStore __unused *persistentStore = [managedObjectStore addInMemoryPersistentStore:&error];
NSPersistentStore *persistentStore = [managedObjectStore addSQLitePersistentStoreAtPath:storePath fromSeedDatabaseAtPath:seedPath withConfiguration:nil options:nil error:&error];
NSAssert(persistentStore, @"Failed to add persistent store with error: %@", error);
/*
RESTKIT
*/
// Create the managed object contexts
[managedObjectStore createManagedObjectContexts];
managedObjectStore.managedObjectCache = [[RKInMemoryManagedObjectCache alloc] initWithManagedObjectContext:managedObjectStore.persistentStoreManagedObjectContext];
And then my mappings are being set within the TableViewController as per:
RKManagedObjectStore *managedObjectStore = [RKManagedObjectStore defaultStore];
NSManagedObjectContext* context = [managedObjectStore mainQueueManagedObjectContext];
NSString *rootKeyPath;
rootKeyPath = @"body";
NSString *endpoint = @"account/login.json";
RKEntityMapping *entityMapping = [RKEntityMapping mappingForEntityForName:@"User" inManagedObjectStore:managedObjectStore];
[entityMapping addAttributeMappingsFromDictionary:@{
@"api_token":@"token",
@"email": @"email",
@"first_name": @"name",
@"last_name": @"surname"
}];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:entityMapping pathPattern:endpoint keyPath:rootKeyPath statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:[TSI_SERVER stringByAppendingString:endpoint]]];
RKManagedObjectRequestOperation *managedObjectRequestOperation = [[RKManagedObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[ responseDescriptor ]];
//managedObjectRequestOperation.managedObjectContext = self.managedObjectContext;
[[NSOperationQueue currentQueue] addOperation:managedObjectRequestOperation];
But whenever I try to retrieve the data after the view is loaded I get the following error in the console (for security reasons I've masked the name and server my App uses):

Does anyone have an idea about what could be the problem?
Thanks!
