How to parsing JSON object in iPhone SDK (XCode) using JSON-Framework

Question

I have JSON object like this :

{ "data":
  {"array":
    ["2",
       {"array":
          [
            {"clientId":"1","clientName":"Andy","job":"developer"},
            {"clientId":"2","clientName":"Peter","job":"carpenter"}
          ]
        }
     ]
   },
 "message":"MSG0001:Success",
 "status":"OK"
}

I want to get the array[0] value (2) and array[1] value (clientId, clientName, job) using JSON-Framework. Do you have any idea how to do that?

Answer 1

Assuming you've followed the instructions to install JSON-Framework into your project, here's how you use it (taken from the docs here) :

// Parse the string into JSON
NSDictionary *json = [myString JSONValue];

// Get the objects you want, e.g. output the second item's client id
NSArray *items = [json valueForKeyPath:@"data.array"];
NSLog(@" client Id : %@", [[items objectAtIndex:1] objectForKey:@"clientId"]);

Answer 2

thank you for your answer, my problem solved, I modify a little bit from your code, here are:

// Parse the string into JSON
NSDictionary *json = [myString JSONValue];

// Get all object
NSArray *items = [json valueForKeyPath:@"data.array"];
NSArray *array1 = [[items objectAtIndex:1] objectForKey:@"array"];
NSEnumerator *enumerator = [array1 objectEnumerator];
NSDictionary* item;
while (item = (NSDictionary*)[enumerator nextObject]) {
   NSLog(@"clientId = %@",  [item objectForKey:@"clientId"]);
   NSLog(@"clientName = %@",[item objectForKey:@"clientName"]);
   NSLog(@"job = %@",       [item objectForKey:@"job"]);
}
