在ios中以相同顺序解析来自服务器的JSON响应

Question

i have an app which fetches JSON response from server. the JSON response from server looks as follows:

{"status":"SUCCESS","message":"XYZ","token":"ABCDEFGHIJ"}

now i need to store this in a NSDictionary for further parsing. so i use the following approach:

    urldata1=[NSURLConnection sendSynchronousRequest:theRequest returningResponse:&res   error:nil]; NSDictionary
    *myDictionary=[NSJSONSerialization JSONObjectWithData:urldata1 options:NSJSONReadingMutableContainers error:nil];
 }

but now the dictionary i get looks as follows:

{
    message = "XYZ";
    status = SUCCESS;
    token = "ABCDEFGHIJ";
}

So i see that the dictionary has been sorted on the basis of keys... is there a way to reproduce the exact same response from server in my dictionary..

Answer 1

It doesn't matter in what order the NSDictionary is because you retrieve the object from the dictionary with keys. So if you want to access the status first use this code

NSString *status  = [myDictionary objectForKey@"status"];
NSString *message = [myDictionary objectForKey@"message"];
NSString *token = [myDictionary objectForKey@"token"];

And you can access a Dictionary inside a Dictionary like this

NSDictionary *dict= [myDictionary objectForKey@"SomeOtherDictionary"];

Answer 2

Sorting a dictionary is meaningless. You need to first create an array which will sort according to your needs.

You can refer Sorting NSDictionary from JSON for UITableView for further explanations.
