How to get the values from nested JSON - Objective c

Question

I am trying to get some keys and values from below nested JSON response. Below I have mentioned my JSON response structure, I need to get the all keys(Red, Green) and key values(Color and ID) from the below response and load into the Array for tableview cell value.

FYI: I have tried by using NSDictionary but I am getting all the time unordered values. I need to get ordered values also. Please help me!

{
response: {

      RED: {

        Color: "red",
        color_id: "01",

             },

      GREEN: {

        Color: "green",
        color_id: "02",

              }
},

Colorcode: { },
totalcolor: "122"
}

My Code:

    NSError *error;
    NSDictionary *jsonDictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
    NSArray *responsData = [jsonDictionary objectForKey:@"response"];
    NSLog("%@",[responsData objectAtIndex:0]); // here I am getting bad exception 

    NSDictionary *d1 = responsData.firstObject;
    NSEnumerator *enum1 = d1.keyEnumerator;
    NSArray *firstObject = [enum1 allObjects];

Dictionaries are unordered, so if you want the order preserved, you have to change the original JSON so that the data within `response` is an array, not a dictionary. — Rob, Jul 23 '15 at 12:21
Yes I agree. I am asking how can I get keynames and Keyvalues without mentioning 'keyname (like: Red)'. how to load that values into seperate array for tableview. If you have sample code share here! Thanks @Rob — Apple_Ajay, Jul 23 '15 at 12:25
@Apple_Ajay Can you post the original JSON response ? The JSON in the question is not a valid JSON. — GoodSp33d, Jul 23 '15 at 12:29
response = [responsData objectAtIndex:0]; response it is dictionary format in your json — Pravin Tate, Jul 23 '15 at 12:30
Yes. Its not a valid because we should give quotes for all keys and key values. @GoodSp33d — Apple_Ajay, Jul 23 '15 at 12:32

I have create JSON data through coding so don't consider it just check the following answer

 /// Create dictionary from following code
        /// it just for input as like your code
        NSMutableDictionary * dict = [[NSMutableDictionary alloc] init];
        NSMutableDictionary * innr = [[NSMutableDictionary alloc] init];
        [innr setObject:@"red" forKey:@"Color"];
        [innr setObject:@"01" forKey:@"color_id"];
        NSMutableDictionary * outer = [[NSMutableDictionary alloc] init];
        [outer setObject:innr forKey:@"RED"];

        innr = [[NSMutableDictionary alloc] init];
        [innr setObject:@"green" forKey:@"Color"];
        [innr setObject:@"02" forKey:@"color_id"];

        [outer setObject:innr forKey:@"GREEN"];

        [dict setObject:outer forKey:@"response"];

       // ANS ------ as follow
        // get keys from response dictionary
        NSMutableArray * key = [[NSMutableArray alloc] initWithArray:[dict[@"response"] allKeys]];

        // sort as asending order
        NSSortDescriptor* sortOrder = [NSSortDescriptor sortDescriptorWithKey: @"self" ascending: YES];
        key =  (NSMutableArray *)[key sortedArrayUsingDescriptors: [NSArray arrayWithObject: sortOrder]];


        // access inner data from dictonary
        for (NSString * obj in key) {
            NSLog(@"%@",dict[@"response"][obj][@"Color"]);
            NSLog(@"%@",dict[@"response"][obj][@"color_id"]);
        }

I think you want same and it will help you!

Awesome Answer. How to load that color and color_ID into seperate Array for tableview. I know its simple any way post here. It will helping others. Thank you. Great work @Pravin – Apple_Ajay Jul 23 '15 at 12:47
Create two array and fill those in that for loop. And if it helpfull for you please upvote or accept so other can refer it – Pravin Tate Jul 23 '15 at 12:50
@Apple_Ajay Do not load `color` and `color_id` into separate arrays. You want a single array of dictionaries (that way if you sort them, by color name or by color id, they'll stay together). – Rob Jul 23 '15 at 12:52
dict[@"response"][obj] fill it in array – Pravin Tate Jul 23 '15 at 12:53
NSArray *menuArray = jsonDictionary[@"response"][obj][@"Color"]; It's making bad exception into tableview delegate. @PravinTate – Apple_Ajay Jul 23 '15 at 13:02
What are you doing man as per your question you need access content from json with ascending format so as per your question I have give you correct answer. Now you are asking for something else. Which is not good. So please accept it and vote up. And edit your question so I will update my answer accordingly – Pravin Tate Jul 23 '15 at 13:08

If you're stuck with this JSON, if you want an array of the values, you can do the following:

NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSDictionary *response = json[@"response"];
NSArray *colors = [response allValues];

If you need that array of colors sorted by color_id, for example, you can sort that yourself:

NSArray *sortedColors = [colors sortedArrayUsingDescriptors:@[[[NSSortDescriptor alloc] initWithKey:@"color_id" ascending:TRUE]]];
