[NSURLConnection sendAsynchronousRequest:request queue:[[NSOperationQueue alloc]init] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
            dispatch_async(dispatch_get_main_queue(),^{

                if([data length]>0 && connectionError==nil)

Issue is in your below statement. Per Apple documentation NSJSONReadingMutableContainers option should be used for arrays and dictionaries. Please try with NSJSONReadingAllowFragments.

NSMutableDictionary *jsonResponse=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];

Constants NSJSONReadingMutableContainers Specifies that arrays and dictionaries are created as mutable objects.

Available in iOS 5.0 and later. NSJSONReadingMutableLeaves Specifies that leaf strings in the JSON object graph are created as instances of NSMutableString.

Available in iOS 5.0 and later. NSJSONReadingAllowFragments Specifies that the parser should allow top-level objects that are not an instance of NSArray or NSDictionary.

Available in iOS 5.0 and later.
