Accepted Answer

You are setting the response parser to `AFHTTPResponseSerializer` and not `AFJSONResponseSerializer`. So the response is never parsed a JSON.

So change

```
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
```

to

```
manager.responseSerializer = [AFJSONResponseSerializer serializer];
```

As mentioned in you comment the server is delivering the content `text/html`, if possible the server should say the content is op type `application/json`, `text/json` or `text/javascript`.

If it is not possible to change the servers content type you can tell the `AFJSONResponseSerializer` to accept `text/html` like:

```
AFJSONResponseSerializer *jsonReponseSerializer = [AFJSONResponseSerializer serializer]; 
// This will make the AFJSONResponseSerializer accept any content type
jsonReponseSerializer.acceptableContentTypes = nil;
manager.responseSerializer = jsonReponseSerializer;
```
