ios - Parse JSON response with AFNetworking

Question

I've setup a JSON post with AFNetworking in Objective-C and am sending data to a server with the following code:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"name": deviceName, @"model": modelName, @"pin": pin};
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"Content-Type" forHTTPHeaderField:@"application/json"];
[manager POST:@"SENSORED_OUT_URL" parameters:parameters

success:^(AFHTTPRequestOperation *operation, id responseObject)
{
    NSLog(@"JSON: %@", responseObject);
}

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

I'm receiving information through the same request, and want to send the data to a NSString. How would I go about doing that with AFNetworking?

Answer 1

responseObject is either an NSArray or NSDictionary. You can check at runtime using isKindOfClass::

if ([responseObject isKindOfClass:[NSArray class]]) {
    NSArray *responseArray = responseObject;
    /* do something with responseArray */
} else if ([responseObject isKindOfClass:[NSDictionary class]]) {
    NSDictionary *responseDict = responseObject;
    /* do something with responseDict */
}

If you really need the string of the JSON, it's available by looking at operation.responseString.
