    "student": {
        "name": "b",
        "std": "d",
        "subjects": [{"id":"1","id":"2","id":"3"}]

Any suggestion what m i missing?

Thanks

If subjects is a dictionary it shouldn't have the square brackets — Jordan Davies, Jan 07 '16 at 16:18

Use NSJSONSerialization :

NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionaryOrArrayToOutput 
                  options:NSJSONWritingPrettyPrinted error:&error];

And for your "slash" problem : https://stackoverflow.com/a/19651309/3222713
