parse json from post request ios afnetworking

Question

I'm working on an iOS app (pretty new to iOS) and I have my registration flow working where i post data to my server... The server returns JSON, but my question is, how do I parse that into variables?

The data that it returns is:

 {"token":"67f41f60-9a9a-11e3-8310-11b6baf18c40","userId":13,"stationId":1}

The code I'm using to make the post request is:

 [manager POST:@"http://localhost:3000/service/register_user/" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);


} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error!!!!!: %@", error);
}];

Also, when I make the post request, this is what I get in the log in xcode

Answer 1

Is your server configured to respond in text/json application/json ?

and/or have you set this?

manager.responseSerializer.acceptableContentTypes

it takes a NSSet of content types this parser will attempt to parse, if you cannot change the server to respond in json you can add text/html into that set, so the parser will parse it anyway.
