    1. 创建webView时使用:作用是允许h5多页面,手势滑动
    wkWebView.allowsBackForwardNavigationGestures = true
    
    2. 因为App系统自带侧滑手势返回,所以要这样做:
    //监听侧滑手势
    let swiperGesture = UISwipeGestureRecognizer(target: self, action: #selector(handleNavigationTransition(_:)))
    swiperGesture.delegate = self // 设置手势代理,拦截手势触发
    view.addGestureRecognizer(swiperGesture)
    navigationController?.interactivePopGestureRecognizer?.isEnabled = true
    navigationController?.interactivePopGestureRecognizer?.delegate = self
    

    第二种方法:

    // handleNavigationTransition:为系统私有API,即系统自带侧滑手势的回调方法,我们在自己的手势上直接用它的回调方法
        UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handleNavigationTransition:)];
        panGesture.delegate = self; // 设置手势代理,拦截手势触发
        [self.view addGestureRecognizer:panGesture];
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
        self.navigationController.interactivePopGestureRecognizer.delegate = self;
    
    需求是左滑手势调用h5返回上一级,逐级返回。利用wkWebView.canGoBack属性实现
    - (void)handleNavigationTransition:(UIGestureRecognizer *)gap{
        //    NSLog(@"用户左滑了手势啊");
        if (_wkWebView.canGoBack==YES) {
            [_wkWebView goBack];
        }else{
            NSLog(@"此时不能左滑");
        }
    }
