Question

Perhaps I am over-thinking or confusing myself, but my head is stuck in a loop over this and I cannot break out.

I have a a JSON of the format: (Validated at http://jsonformatter.curiousconcept.com/)

{
  id: 1,
  sections: "5",
  total: "10",
  result: {
    3: 00PM: [
      {
        name: "Anurag",
        status: "Web"
      },
      {
        name: "Anurag2",
        status: "Web2"
      }
    ],
    5: 00PM: [
      {
        name: "Anurag",
        status: "Seated"
      }
    ],
    6: 00PM: [
      {
        name: "Anurag4",
        status: "Web4"
      },
      {
        name: "Anurag5",
        status: "Web5"
      },
      {
        name: "Anurag6",
        status: "Web6"
      },
      {
        name: "Anurag7",
        status: "Web7"
      }
    ]
  }
}

I have this so far:

        NSDictionary *dict = [response JSONValue];
        NSDictionary *results = [dict objectForKey:@"result"];

        NSInteger num_results = [[dict valueForKey:@"total"] intValue];
        NSInteger num_sections = [[dict valueForKey:@"sections"] intValue];

        NSMutableArray *sections = [[NSMutableArray alloc] initWithCapacity:num_sections];
        NSMutableArray *objarr = [[NSMutableArray alloc] initWithCapacity:num_results];
        NSMutableArray *obj= [[NSMutableArray alloc] initWithCapacity:num_sections];
        NSMutableArray *temp = [[NSMutableArray alloc] initWithCapacity:num_results];

        for (NSString* key in results) {
            NSLog(@"Key: %@", key); // prints out 3:00 PM...5:00 PM etc...
            [obj addObject:[results objectForKey:key]]; // nested objects within each key are saved in the array
            NSLog(@"Object 1: %@", obj);
        }

        for (int i = 0; i < [obj count]; i++) {
            //NSLog(@"Object 2: %@", [obj objectAtIndex:i]);
            [temp addObject:[obj objectAtIndex:i]]; // I take each object from previous array and save it in a temp array
            for (int i = 0; i < num_results; i++) {
                NSLog(@"Object 3: %@", [temp objectAtIndex:i]);
                **[objarr addObject:[temp objectAtIndex:i]]; // I want to extract the object within the object but cannot get it to work**
            }   
        }

I am able to make an array of objects within each of the 3 keys inside results. But I am not able to get each of the objects inside them as a separate object and save them in an array.

For example, in an NSArray I have:

Object 3: (
        {
        name = "Anurag ";
        status = Web;
    },
        {
        name = "Anurag ";
        status = Web;
    }
)

How can I get the two objects inside this object and save them both in an array?
I guess the main issue is I cannot refer to a key name to get the individual object.

You can use the following code,

NSDictionary *json = [response JSONValue];

// Get the objects you want
NSArray *items = [json valueForKeyPath:@"result.6: 00PM"];

This will return an NSArray with the objects for the key 6: 00PM
