//在发送请求之前，决定是否跳转,在这个WKNavigationDelegate方法里

- (void)webView:(WKWebView*)webView decidePolicyForNavigationAction:(WKNavigationAction*)navigationAction decisionHandler:(void(^)(WKNavigationActionPolicy))decisionHandler{

decisionHandler(WKNavigationActionPolicyAllow);

if ([navigationAction.request.URL.absoluteString hasPrefix:@"weixin://")

{

    //decisionHandler(WKNavigationActionPolicyCancel);

    if ([[UIApplication sharedApplication] canOpenURL:navigationAction.request.URL])

    {

        if ([[UIApplication sharedApplication] respondsToSelector:@selector(openURL:options:completionHandler:)])

        {

            [[UIApplication sharedApplication] openURL:navigationAction.request.URL options:@{UIApplicationOpenURLOptionUniversalLinksOnly: @NO} completionHandler:^(BOOL success) {

            }];

        }

        else

        {

            [[UIApplication sharedApplication] openURL:navigationAction.request.URL];

        }

    }

}

}

存在的问题:不能返回APP,而是返回了浏览器,希望解决的大神私聊说下方案,谢谢!
