发送滑动手势到superview

Question

当滑动方向是从左到右时，我需要将滑动事件从uiwebview转发到它的超级视图（uiscrollview）。所以，我正试图像这样做什么

self.swipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
[self.webView addGestureRecognizer:self.swipeGestureRecognizer];

和处理程序

-(void) handleSwipe:(UISwipeGestureRecognizer*) swipeRecognizer {

if(swipeRecognizer.direction == UISwipeGestureRecognizerDirectionRight) {

   //change to dispatching swipe to scrollview
    CGPoint contentOffset = [self.scrollView contentOffset];
    contentOffset.x -= 1024;
    [self.scrollView setContentOffset:contentOffset animated:YES];
}}

相反，更改滚动视图偏移我不想向前滑动它。我怎么能这样做？
