在UIWebView，iPad中的手势

Question

现在这是我必须在webView中处理手势的代码：

    UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc]     initWithTarget:self action:@selector(swipeRightAction:)];
swipeRight.direction = UISwipeGestureRecognizerDirectionRight;
swipeRight.delegate = self;
[webView1 addGestureRecognizer:swipeRight];
//</code>

UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc]     initWithTarget:self action:@selector(swipeLeftAction:)];
swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
swipeLeft.delegate = self;
[webView1 addGestureRecognizer:swipeLeft];


[super viewDidLoad];
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer     shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES;
}

- (void)swipeRightAction:(id)ignored
{
NSLog(@"Swipe Right");
//add Function
}

- (void)swipeLeftAction:(id)ignored
{
NSLog(@"Swipe Left");

scrollView.contentOffset = CGPointMake(webView2.frame.origin.x,  webView1.frame.origin.y);
}

此代码的目的是滚动浏览scrollView中并排的三个webView。

它适用于第一个webView，但最终我想将手势放到所有webView上，如果我尝试将它放在第二个上，它就不适用于第一个。关于为什么以及可能解决这个问题的任何想法？提前谢谢！

也许手势识别器在托管UIWebViews的视图中效果最佳。瞧，你只需要一个识别器，这样可以使管理变得更容易。
