Question

I know my request is formatted properly, but the response I get from the web service is not an NSDictionary.

1. Why would it not be an NSDictionary?

2. How can I tell what kind of object “responseObject” is?

   AFHTTPRequestOperation *operation = [[AFParseAPIClient sharedClient]  HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
       if ([responseObject isKindOfClass:[NSDictionary class]]) {
           NSLog(@"Response for %@: %@", className, responseObject);
           [self writeJSONResponse:responseObject toDiskForClassWithName:className];
       }else{
           //NSLog(@"Response NOT NSDictionary: %@", [responseObject class]);
           NSString *str = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
           NSLog(@"str: %@", str);
       }
   } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
       NSLog(@"Request for class %@ failed with error: %@", className, error);
   }];
   

Here’s what I get:

//Response NOT NSDictionary: <7b227265 73756c74 73223a5b 7b22636f ...>

EDIT: here’s what I get back:

str: {"results":[{"desc":"My description.","device_iPad":true,"device_iPhone":true,"createdAt":"2012-09-05T18:36:11.431Z","updatedAt":"2012-09-05T22:00:52.199Z"}]}

Answer 1

Would this be useful to you? It’s from AFNetworking github project

NSURL *url = [NSURL URLWithString:@"https://gowalla.com/users/mattt.json"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];

AFJSONRequestOperation *operation = [AFJSONRequestOperationJSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSLog(@"Name: %@ %@", [JSON valueForKeyPath:@"first_name"], [JSON valueForKeyPath:@"last_name"]);
} failure:nil];

[operation start];

Give it a try, it’s pretty straightforward. *If it’s still an array do [[JSON objectAtIndex:0] objectForKey@"desc /*(or whatever)*/"]
