Multi root with a GET request - ios

Question

I am searching a way to map 2 different arrays with the following JSON
"establishments": [
{
"id": 1,
"name": "Boudin Sourdough Bakery and Cafe",
"address": "1 Stockton St",
"zip_code": "94108",
"city": "San Francisco",
"country": "us",
"phone_number": "",
"position": {
"latitude": 37.78590500000001,
"longitude": -122.406289
},
"distance_from": 13.75783097391759
}
],
"places": [
{
"id": 3,
"name": "Private Place",
"position": {
"latitude": 37.78583400000001,
"longitude": -122.406417
},
"is_private": false,
"distance_from": 0
}
]
I have 2 different mappings. One for establishment and another for place. I found some help with the documentation but it's working only for PUT or POST requests.
Currently, I have the following request
[session.objectManager getObjectsAtPathForRouteNamed:APICallSearchSearchPlaceRouteName object:nil parameters:params success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSArray * resultPlaces=mappingResult.array;
[delegate APICallDidSearch:resultPlaces];
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSError* myError=[self catchCustomErrorInRKError:error setDomain:#"Search"];
if (myError.code == NSURLErrorCancelled) return;
[delegate APICallDidFailSearch:myError];
}];
Mapping & Mapping Descriptor
RKEntityMapping *establishmentMapping = [APICallEstablishment RKGetEstablishmentMappingForManagedObjectStore:self.appDelegate.managedObjectStore];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:establishmentMapping
method:RKRequestMethodGET
pathPattern:APICallSearchSearchPlacePattern
keyPath:#"establishments"
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[session.objectManager addResponseDescriptor:responseDescriptor];
I tried to adapt the example to my case with that (just before my request written above)
RKManagedObjectRequestOperation *operation = [session.objectManager appropriateObjectRequestOperationWithObject:establishmentMapping method:RKRequestMethodGET path:#"/whatever" parameters:nil];
operation.targetObject = nil;
//Does it still exist ? (XCode says an error)
//operation.targetObjectID = nil;
[session.objectManager enqueueObjectRequestOperation:operation];
Thank you in advance for your help.

Using session.objectManager getObjectsAtPathForRouteNamed... is a good option (better than trying to use RKManagedObjectRequestOperation directly).
You need to create another response descriptor, like responseDescriptor, but for places key path and mapping.
