让UIWebView响应手势操作

UIPinchGestureRecognizer *swipeGesture = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(detailSwipeFromLeft:)];

[self.view addGestureRecognizer:swipeGesture];

swipeGesture.delegate = self;

并实现delegate方法

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

{

    return YES;

}

这样就能让UIWebView响应手势操作了
