本文介绍如何在UIWebView中实现左右滑动翻页功能。通过使用UISwipeGestureRecognizer手势识别器，作者实现了向左和向右滑动时触发翻页的动作。此外，还列举了UIGestureRecognizer的多个子类。

最近需要在UIWebView里实现左右划动翻页的功能，发现用UITouch事件没效果，在官方文档里找了个用UIGestureRecognizer实现的方法：

 UISwipeGestureRecognizer  *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe:)];
    [webView addGestureRecognizer:swipeRight];
    [swipeRight release];

    UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe:)];
    swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
    [webView addGestureRecognizer:swipeLeft];
    [swipeLeft release];

---------------------华丽的分割-------------------

-(void)swipe:(UISwipeGestureRecognizer *)g{
    if (g.direction == UISwipeGestureRecognizerDirectionRight) {
        [self prevPage];
    } else {
        [self nextPage];  
    }
}

UISwipeGestureRecognizer 是UIGestureRecognizer的子类，还有以下几个：

UITapGestureRecognizer
UIPinchGestureRecognizer
UIRotationGestureRecognizer
UISwipeGestureRecognizer
UIPanGestureRecognizer
UILongPressGestureRecognizer
