My code currently looks like this 

NSURL *URL = [NSURL URLWithString:URLForSend];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]
                                     initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
 {
     NSLog(@"%@", responseObject);
     [BoxJsonDataHelper gotNewJson:responseObject];
 } failure:^(AFHTTPRequestOperation *operation, NSError *error)
 {
     NSLog(@"Request Failure Because %@",[error userInfo]);
 }];

[operation start];

But when trying to edit dictionaries in object received, I get an error about using methods that belongs to a mutable dictionary rather than a dictionary. How do I make AFNetworking use nested mutable objects instead?

You tell the AFJSONResponseSerializer that it needs to return mutable containers:

operation.responseSerializer = 
  [AFJSONResponseSerializer serializerWithReadingOptions: NSJSONReadingMutableContainers]

It is all very well documented: http://cocoadocs.org/docsets/AFNetworking/2.0.0/

  • Thank, I understood wrong from the documentation that it is suppose to be the default. – Yoav Schwartz Nov 15 '13 at 16:54

    BTW this option optimizes a bit memory handling, because it doesn't copy mutable container into immutable one. And to return also mutable leaves: manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions: NSJSONReadingMutableContainers | NSJSONReadingMutableLeaves]; – Borzh Oct 13 '15 at 12:46
