WKWebView在遵循WKNavigationDelegate代理后，會有一個- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler;方法，監(jiān)聽特定的URL

//網(wǎng)頁交互
-(void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{
    NSString *lowStr = navigationAction.request.URL.absoluteString;
//    NSString *urlStr = [NSString strurl]
    PTTLog(@"跳轉(zhuǎn)網(wǎng)址為%@",lowStr);
    if ([lowStr containsString:@"qla"]) {
        [[UIApplication sharedApplication] openURL:navigationAction.request.URL];
        decisionHandler(WKNavigationActionPolicyCancel);
    }else{
        decisionHandler(WKNavigationActionPolicyAllow);
    }
}

然后在AppDelegate文件中添加-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url;方法，并解析URL，來實現(xiàn)對應(yīng)功能。

-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
    if (!url) {
        return NO;
    }
    
    NSString *urlString=[url absoluteString];
    
    if (![urlString containsString:@"?"]) {
        [_tabViewController setSelectedIndex:0];
        return YES;
    }
    //獲取問號的位置，問號后是參數(shù)列表
    NSRange range = [urlString rangeOfString:@"?"];
    
    //獲取參數(shù)列表
    NSString *propertys = [urlString substringFromIndex:(int)(range.location+1)];
    
    //進行字符串的拆分，通過&來拆分，把每個參數(shù)分開
    NSArray *subArray = [propertys componentsSeparatedByString:@"&"];
    
    //把subArray轉(zhuǎn)換為字典
    //tempDic中存放一個URL中轉(zhuǎn)換的鍵值對
    NSMutableDictionary *tempDic = [NSMutableDictionary dictionaryWithCapacity:4];

    for (int j = 0 ; j < subArray.count; j++)
    {
        //在通過=拆分鍵和值
        NSArray *dicArray = [subArray[j] componentsSeparatedByString:@"="];
        if ([dicArray[0] isEqualToString:@"title"]) {
            //urf8轉(zhuǎn)碼
            NSString *str = dicArray[1];
            NSString *utf = [str stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
            [tempDic setObject:utf forKey:dicArray[0]];
        }else{
//        PTTLog(@"再把每個參數(shù)通過=號進行拆分：n%@", dicArray);
        //給字典加入元素
        [tempDic setObject:dicArray[1] forKey:dicArray[0]];
        }
    }
    UITabBarController *tabbarVC  = (UITabBarController *)self.window.rootViewController;
    if ([tabbarVC isKindOfClass:[QLStartADViewController class]]) {
        return NO;
    }
    UINavigationController *navigationVC = (UINavigationController *)tabbarVC.selectedViewController;

    if (((NSNumber *)[tempDic objectForKey:@"action"]).intValue == 101) {
        //跳轉(zhuǎn)到首頁
        [tabbarVC setSelectedIndex:0];
        [navigationVC popToRootViewControllerAnimated:YES];
    }else if (((NSNumber *)[tempDic objectForKey:@"action"]).intValue == 102){
        //快捷入金
        if (!readloginState) {
            [navigationVC pushViewController:[[USStartUpController alloc]init] animated:YES];
        }else{
            if (readisOpenAcount) {
                TransferMoneyViewController *vc = [[TransferMoneyViewController alloc]init];
                [navigationVC pushViewController:vc animated:YES];
                vc.activity = [tempDic objectForKey:@"activity"];
                vc.tradeRoute = [tempDic objectForKey:@"tradeRoute"];
            }else{
                OpenAccountInfoController *openVc = [[OpenAccountInfoController alloc]init];
              [navigationVC pushViewController:openVc animated:YES];
            }
        }
    }
    return YES;
}
