I'm sending off 2 requests simultaneously with Restkit and I receive a response back from both of them, but only one of the requests receives any objects. If I send them off one by one, then my objectloader receives all objects.

First request:

self.firstObjectManager = [RKObjectManager sharedManager];
[self.firstObjectManager loadObjectsAtResourcePath:[NSString stringWithFormat: @"/%@.json", subUrl] usingBlock:^(RKObjectLoader *loader){
    [loader.mappingProvider setObjectMapping:designArrayMapping forKeyPath:@""];
    loader.userData = @"design";
    loader.delegate = self;
    [loader sendAsynchronously];
}];

Second request:

self.secondObjectManager = [RKObjectManager sharedManager];
[self.secondObjectManager loadObjectsAtResourcePath:[NSString stringWithFormat: @"/%@.json", subUrl] usingBlock:^(RKObjectLoader *loader){
    [loader.mappingProvider setObjectMapping:designerMapping forKeyPath:@""];
    loader.userData = @"designer";
    loader.delegate = self;
    [loader sendAsynchronously];
}];

My objecloader:

-(void)objectLoader:(RKObjectLoader *)objectLoader didLoadObjects:(NSArray *)objects
{
    //NSLog(@"This happened: %@", objectLoader.userData);
    if (objectLoader.userData == @"design") {
        NSLog(@"Design happened: %i", objects.count);
    }else if(objectLoader.userData == @"designer"){
        NSLog(@"designer: %@", [objects objectAtIndex:0]);
    }

}

My response:

Update: Setting my base url

RKURL *baseURL = [RKURL URLWithBaseURLString:@"http://iphone.meer.li"];
[RKObjectManager setSharedManager:[RKObjectManager managerWithBaseURL:baseURL]];

Solution

Problem was that I used the shared manager for both object managers, so I ended up doing:

RKURL *baseURL = [RKURL URLWithBaseURLString:@"http://iphone.meer.li"];
RKObjectManager *myObjectManager = [[RKObjectManager alloc] initWithBaseURL:baseURL];
self.firstObjectManager = myObjectManager;

and:

RKURL *baseURL = [RKURL URLWithBaseURLString:@"http://iphone.meer.li"];
RKObjectManager *myObjectManager = [[RKObjectManager alloc] initWithBaseURL:baseURL];
self.secondObjectManager = myObjectManager;
