how to store data in object and that object store in array in ios

Question

How can I store these three dictionaries in an object and those three objects store in an array? how can I retrive this data from array?

    [    
            {
                    "gender_desc" = Male;
                    "gender_id" = 1;
                    "gender_isactive" = 1;
            },
            {
                    "gender_desc" = Female;
                    "gender_id" = 2;
                    "gender_isactive" = 1;
            },
            {
                    "gender_desc" = Other;
                    "gender_id" = 3;
                    "gender_isactive" = 1;
            }

A dictionary is an object, so you could just create three dictionaries and store those in an array, or you could create a struct or object. It looks like this may be JSON, so are you asking how you can parse the JSON into data structures? — Paulw11, Dec 11 '15 at 19:41

Using this,

NSError *error;
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];

you can parse your json data into dictionaries. First of all this json structure is wrong. Json should be like :

{
  "gender_detail":[
  {
        "gender_desc" = Male;
        "gender_id" = 1;
        "gender_isactive" = 1;
  },
  {
        "gender_desc" = Female;
        "gender_id" = 2;
        "gender_isactive" = 1;
  },
  {
        "gender_desc" = Other;
        "gender_id" = 3;
        "gender_isactive" = 1;
  }
]
}

Then create a mutable array and store these values :

NSMutableArray *dataArray = [[NSMutableArray alloc] init];
[dataArray addObjectsFromArray:[dictionary valueForKey:@"gender_details"]];

After this array is ready. Now suppose you want gender_desc value of first object.

NSString *gender_desc = [[dataArray objectAtIndex:0] valueForKey:@"gender_desc"];

Do likewise for other details.

So you want to parse JSON into NSDictionaries, NSArrays and the like? The are many libraries that will happily accommodate this task, or Apple's docs can help you roll your own. Looking on SO, here just one place to start, Convert JSON feed to NSDictionary
