- (UIViewController *)getCurrentVC
    {
            UIViewController *result = nil;
               
            UIWindow * window = [[UIApplication sharedApplication] keyWindow];
            if (window.windowLevel != UIWindowLevelNormal)
                {
                        NSArray *windows = [[UIApplication sharedApplication] windows];
                        for(UIWindow * tmpWin in windows)
                            {
                                    if (tmpWin.windowLevel == UIWindowLevelNormal)
                                        {
                                                window = tmpWin;
                                                break;
                                            }
                                }
                    }
               
            UIView *frontView = [[window subviews] objectAtIndex:0];
            id nextResponder = [frontView nextResponder];
               
            if ([nextResponder isKindOfClass:[UIViewController class]])  
                    result = nextResponder;  
            else 
                    result = window.rootViewController;  
               
            return result;  
    }
