Fetch the data from JSON response

I am getting JSON response like this

[{"UserId":250,"Response":"success"}]

I used below code to fetch the UserId 

  NSDictionary *jsonDict1 = [NSJSONSerialization JSONObjectWithData:receivedData options: NSJSONReadingMutableContainers error: &e];

userId = [jsonDict1 valueForKey:@"UserId"];

but i am getting user id in the form of ( 250 ) i need to get the data without parentheses

The root object in your JSON is an array you can tell this as there are square brackets around the object (which uses curly braces).

When you call valueForKey: on an array it will return a new array that contains the results of calling valueForKey: on each of the elements.

If you just want to get this first item you need to do this

NSArray *results = [NSJSONSerialization JSONObjectWithData:receivedData 
                                                   options:NSJSONReadingMutableContainers 
                                                     error:&error];

userId = results.firstObject[@"UserId"];

               Array
+-------------------------------------+
|                                     |
v                                     v
[ {"UserId":250,"Response":"success"} ]  
  ^                                 ^
  |                                 |
  +---------------------------------+
         1st object in array
