How to get JSON out of AFNetworing 2.0 GET Method - ios

Question

I am using AFNetworking to make a bunch of API calls at once to Instagram. I am using AFNetworking 2.0 AFHTTPSessionManager GET request.
I am using a for loop to create the URL which requires a location ID that I am searching. The for loop then makes in this case 3 separate API calls and stores each response in an array.
I then create a mutable array to store the objects in the array. I need to get the mutable array once it has all three objects in it. I have tried passing the data to another method, but then I get into the same problem - can't really use the array until the previous method is done running.
-(void)sendGetRequestForLocationMedia:(NSMutableArray*)mutableArray{
for (int i = 0; i<3; i++) {
NSString *getLocationMediaString = [[NSString alloc]initWithFormat:#"locations/%#/media/recent?client_id=%#", self.locationIDObjectArray[i], client_id];
NSLog(#"getLocationMediaString %#", getLocationMediaString);
[[LPAuthClient sharedClient]GET:getLocationMediaString parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) {
{
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)task.response;
if (httpResponse.statusCode == 200) {
dispatch_async(dispatch_get_main_queue(), ^{
_locationMediaArray = responseObject[#"data"];
if (!_locationMediaJSONArray) {
_locationMediaJSONArray = [[NSMutableArray alloc]init];
}
for (NSDictionary *dictionary in _locationMediaArray) {
[_locationMediaJSONArray addObject:dictionary];
}
});
}
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(#"Failure %#", error);
}];
}
}
