How to parse JSON response received from a Webservice Response - json

Question

I Have got this Response from WebService
{"d":"{"token":"b502645e-837f-4237-a6ff-d4323f2799dd","timestamp":"09/11/20147:46:43PM"}"}
I want to Parse this String so that i can get output like :
token = b502645e-837f-4237-a6ff-d4323f2799dd
timestamp = 09/11/20147:46:43PM
So that i can Store it into Database.
This is my Code
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
// The request is complete and data has been received
// You can parse the stuff in your instance variable now
/*
NSError *errorJson=nil;
NSString* OuterDict = [NSJSONSerialization JSONObjectWithData:receivedData options:kNilOptions error:&errorJson];
NSLog(#"Outer Dictionary %#",OuterDict);
*/
NSString *responseData = [[NSString alloc]initWithData:receivedData encoding:NSUTF8StringEncoding];
responseData = [responseData stringByReplacingOccurrencesOfString:#" " withString:#""];
responseData = [responseData stringByReplacingOccurrencesOfString:#"\\" withString:#""];
//NSString* encodedString = [responseData stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
//NSLog(#"%#",encodedString);
NSLog(#"Reponse data %#",responseData);
NSError *errorJson=nil;
NSData *jsonData = [responseData dataUsingEncoding:NSUTF8StringEncoding];
jsonData = [jsonData subdataWithRange:NSMakeRange(0, [jsonData length] - 1)];
NSDictionary* OuterDict = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&errorJson];
NSLog(#"Outer Dict %#",OuterDict);
}
I am getting null as Output:
Outer Dict (null)
Can Anyone Help me With this.
Thanks In Advance.

Use following snippets at the top of your method. it will parse your JSON data and returns dictionary. You can perform any operations on Dictionary according to your need.
NSDictionary *dictResponse = [NSJSONSerialization JSONObjectWithData:receivedData options:NSJSONReadingAllowFragments error:&err];
NSLog(#"Response : %#", dictResponse);
Happy coding :)
