Use following shnchronous request, you can use asynchronous request as well,

NSError *error;

  NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:]];

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


 [request setHTTPMethod:@"POST"];
 [request setHTTPBody:jsonData];

  NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
  //NSLog(@"results string = %@",[[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]);


 NSDictionary *temp= [NSJSONSerialization JSONObjectWithData:returnData options:NSJSONReadingMutableContainers error:nil];// This will convert Data to Json format
