objective c - Converting NSString to NSDictionary / JSON

Question

I have the following data saved as an NSString :

 {
    Key = ID;
    Value =         {
        Content = 268;
        Type = Text;
    };
},
    {
    Key = ContractTemplateId;
    Value =         {
        Content = 65;
        Type = Text;
    };
},

I want to convert this data to an NSDictionary containing the key value pairs.

I am trying first to convert the NSString to a JSON objects as follows :

 NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

However when I try :

NSString * test = [json objectForKey:@"ID"];
NSLog(@"TEST IS %@", test);

I receive the value as NULL.

Can anyone suggest what is the problem ?

I believe you are misinterpreting the JSON format for key values. You should store your string as

NSString *jsonString = @"{"ID":{"Content":268,"type":"text"},"ContractTemplateID":{"Content":65,"type":"text"}}";
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

Now if you do following NSLog statement

NSLog(@"%@",[json objectForKey:@"ID"]);

Result would be another NSDictionary.

{
    Content = 268;
    type = text;
}

Hope this helps to get clear understanding.
