Restkit - enqueueObjectRequestOperation not being called after adding rootviewcontroller in appdelegate

Question

I have been using Restkit to connect to my API server, and it works perfectly. Now my situation is that I added a checker in my appdelegate.m in didFinishLaunchingWithOptions. it checks if there is already adminID in the coredata. if there was a adminID stored, when the app is relaunched, it will set the rootviewcontroller into a uinavigation controller. but when the uiviewcontroller is called, the Restkit enqueueObjectRequestOperation is not called.

Here's my code:

in appdelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //adminID is fetch from custom Entity in core data
    if(adminID==0){
        AllKommunScreenViewController  *adminController = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"AllKommunScreenID"];
        UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:adminController];

        self.window.rootViewController = navController;
    }
    return YES;
}

Here's my code in the Navigation controller's Rootview:

-(void)fetchData{
    RKObjectMapping *responseMapping = [RKObjectMapping mappingForClass:[Auth class]];
    [responseMapping addAttributeMappingsFromArray:@[@"status", @"sucess", @"data"]];

    NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);

    RKResponseDescriptor *userProfileDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:responseMapping method:RKRequestMethodAny pathPattern:nil keyPath:nil statusCodes:statusCodes];

    NSString *apiPath = [NSString stringWithFormat:@"%@%@", baseURL,@"/api/kommun/all/stats/"];

     NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:apiPath]];
    request setValue:_sharedManager.userAccessToken forHTTPHeaderField:@"X-ACCESS-TOKEN"];

    RKObjectRequestOperation *operation =[[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[userProfileDescriptor]];

    [operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {} failure:^(RKObjectRequestOperation *operation, NSError *error) {}];

    [RKObjectManager sharedManager] enqueueObjectRequestOperation:operation];
}

i called the fetchData in viewWillAppear.

Then i add a breakpoint to the function, and it goes there, the problem is that the restkit is not calling the enqueueObjectRequestOperation.

Please help!!!

By the way, i make a custom core data entity to store the adminID

Why are you calling?

[RKObjectManager sharedManager] enqueueObjectRequestOperation:operation];

I think you should call

RKObjectRequestOperation *operation =[[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[userProfileDescriptor]];

[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

//print something 
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
// print something
}];

[operation start];

If you want to add it to queue of Object Request Operations you should first init RKObjectManager and than call enqueueObjectRequestOperation:

RKObjectManager *manager = [RKObjectManager managerWithBaseURL:baseUrl];

 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:apiPath]];
request setValue:_sharedManager.userAccessToken forHTTPHeaderField:@"X-ACCESS-TOKEN"]; 
RKObjectRequestOperation *operation =[[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[userProfileDescriptor]];

[manager enqueueObjectRequestOperation:operation];
