Map JSON to NSDictionary in Objective-C

Question

I have the following JSON from a Web service:

[
    "{
       "count":2,
       "offers":{
          "0":{
             "nodeID":"654321",
             "publicationDate":"1396272408",
             "title":"My first title",
             "locations":"New York City"
          },
          "1":{
             "nodeID":"123456",
             "publicationDate":"1396272474",
             "title":"My second title",
             "locations":"San Diego"
          }
       },
       "error":"null",
       "result":"success"
    }"
]

I need to map this JSON to a NSDictionary. How can I do that?

I already tried the following

NSString *json = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *parsedObject = [NSJSONSerialization JSONObjectWithData:[json dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&localError];

but it only gives me a dictionary with one object in it. I need to access all the fields of the JSON such as "count", "offers" etc. How can I achieve this?

Answer 1

You JSON output is not a dictionary but an array.

NSString *json = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSarray *parsedObject = [NSJSONSerialization JSONObjectWithData:[json dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&localError];

for(NSDictionary *dict in parsedObject) {
   NSNumber *count = [dict objectForKey:@"count"];

}

But the offer node is just weird, this would be better as an array.

Get your data in this form ... Your json Give error of ".....

   [
      {
           "count": 2,
           "offers":
           {
           "0": {
                     "nodeID": "654321",
                     "publicationDate": "1396272408",
                     "title": "Myfirsttitle",
                     "locations": "NewYorkCity"
                },
           "1": {
                     "nodeID": "123456",
                     "publicationDate": "1396272474",
                     "title": "Mysecondtitle",
                     "locations": "SanDiego"
                }
           },
           "error": "null",
           "result": "success"
      }
   ]

You get data In Array [ having Dictionary in dictionary ....
