What should the return value of a JSON GET or POST look like?

I'm new to JSON and just starting to wrap my head around it's functionality.

I'm trying to see if I can get print some data from some JSON methods. I've been alternating between the first one and the one that is commented out. The ideas is to see if I can get anything printing:

id newConnection =  [scAPI performMethod:@"GET" onResource:@"me/connections.json" withParameters:nil context:nil userInfo:nil];



//  id newConnection =   [scAPI performMethod:@"POST"
//            onResource:@"connections"
//        withParameters:[NSDictionary dictionaryWithObjectsAndKeys:
//                        @"facebook_profile", @"service",
//                        @"imc://connection", @"redirect_uri",
//                        @"touch", @"display", //optional, forces services to use the mobile auth page if available
//                        nil]
//               context:nil
//              userInfo:nil];

   NSLog(@"newConnection %@", newConnection);


   NSLog(@"Is of type: %@", [newConnection class]);



   NSDictionary *dict = [newConnection objectFromJSONString];


for (id key in dict) {

    NSLog(@"key: %@, value: %@", key, [dict objectForKey:key]);

}

The above code doesn't err and I get logs such as:

Does this look right? How do 开发者_如何转开发I properly use these JSON methods to get a dictionary of values?

EDIT 1

To be clear I'm using JSONKit :)

I would personally recommend using the SBJSON library. Getting a dictionary with it is straightforward.

Get a response back from a connection, and then use the following code (where response is an NSString containing the response from the server):

SBJsonParser *parser = [[SBJsonParser alloc] init];
NSArray *returnData = [parser objectWithString:[response stringByReplacingOccurrencesOfString:@"\\\\" withString:@"\\"]];
[parser release];

NSDictionary *returnDict = (NSDictionary *)returnData;

This is unrelated, but for examining JSON data, I would also recommend Online JSON Viewer. You can paste in your JSON strings and view it with a collapsable array structure. Very convenient.
