get values of particular key in nsdictionary

Question

I saved the json parsing result in a dictionary which look like:

{
 "statusCode":"200",
"body":[
  {
     "status":"success",
     "remarks":null
  }
],

"data":[
     "abcd":[
        {
           "category":"a",
           "title":"b",
           "id":"24"
        },
        {
           "category":"c",
           "title":"crd",
           "id":"65"
        },
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        }

     ]
  },
  {
     "efgh":[
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        },
        {
           "category":"sd",
           "title":"sd",
           "id":"1"
        }

                             ]
  },
  {
     "ijkl":[
        {
           "category":"ds",
           "title":"sd",
           "id":"18"
        },
        {
           "category":"sd",
           "title":"sd",
           "id":"1"
        }

     ]
  }
 ]
}

The data for key @"data" can be saved into an array by using

NSMutableArray *getdata=[[NSMutableArray alloc]init];
getcat=[results objectForKey:@"data"];

Now what should I do for the values(category, title, id) inside the first index i.e. "abcd".

If anyone has any knowledge please look upon that.

Thanks to all.

Solution 1

Following will give you the desired object

NSDictionary *dict=[results valueForKeyPath:@"data.abcd"][0];

For individual:

NSString *categoryString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"Category"];
NSString *idString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"id"];
NSString *titleString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"title"];

Also,

NSString *categoryString=dict[@"Category"];
NSString *idString=dict[@"id"];
NSString *titleString=dict[@"title"];

Solution 2

Check like this:

NSString *value=[[[getcate valueForKey:@"abcd"] objectAtIndex:0] valueForKey:@"category"];

Yes I done this already.. NSMutableArray *firstarray=[getcat objectAtIndex:0]; "abcd":[ { "category":"a", "title":"b", "id":"24" }, { "category":"c", "title":"crd", "id":"65" }, { "category":"ds", "title":"sd", "id":"18" } ] But now how to get value inside the abcd i.e. category, title, id

[borrrden]

That's another Dictionary. I don't understand why this gives so many people so much trouble. You already did the exact same thing in this line -> getcat=[results objectForKey:@"data"]; so just do it again. JSON is not rocket science. You can only get about 5 or 6 different types out, and only two collection types. So collections are either arrays (get by number) or dictionaries (get by string).

I am unable to get the value inside the dictionary i.e. category, id, title.

[Anoop Vaidya]

nslog dict, as shown in my answer, and tell what gets printed.

[Minkle Garg]

I got the inside key values by NSString *cat=[dict valueForKeyPath:@"id"][0]; It means to get all the id for a particular keys for example all the ids under "abcd" I have to use for loop.

How to get the "abcd" key name from data? Because i want to show "abcd" as my tableview section title. in my case "abcd" and "efgh" is dynamic.
