ios - 如何在 webView 上打开 Smooch 聊天中的链接，而不是 Safari 浏览器 Swift

Question

我正在使用 Smooch 库将聊天集成到应用程序中。此外，我还实现了通用链接。

编程语言 - Swift / iOS 版本 - 12.4+ / Smooch SDK 版本 7.12

问题：

• 当我点击 Smooch 聊天中的链接时，它会打开我的 Safari 浏览器而不是 webView ！！！ 通用链接正常工作，我可以通过点击其他应用程序（WhatsApp、Safari、电报...）的链接来重定向我

但是，只需点击 smooch 聊天中的链接，就会将我重定向到 Safari 浏览器。我怎样才能留在应用程序中？

这里是主要的 VC，我正在使用 Smooch 聊天加载 webView 和按钮：

override func viewDidLoad() {
    super.viewDidLoad()
    if let data = userDefaults.dictionary(forKey: "data"){
        responseData = data
    }
    loadWebKit()
    checkToken()
    initSmooch()
    setupChatBtnView()
}


//showing smooch chat view
@IBAction func chatBtnDidPress(_ sender: UIButton) {
    Smooch.show()

}

//chat button design
func setupChatBtnView(){
    chatBtnOutlet.layer.cornerRadius = chatBtnOutlet.bounds.self.width / 2.0
    chatBtnOutlet.clipsToBounds = true
    chatBtnOutlet.layer.shadowRadius = 1
    chatBtnOutlet.layer.shadowColor = UIColor(red: 255/255, green: 170/255, blue: 0/255, alpha: 0.5).cgColor
    chatBtnOutlet.layer.shadowOpacity = 0.5
    chatBtnOutlet.layer.shadowOffset = CGSize(width: 0.0, height: 3.0)
    chatBtnOutlet.layer.masksToBounds = false
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)
    Smooch.close()
}

//webkit view url load and adding js event listeners
func loadWebKit(){
    webView.navigationDelegate = self
    webView.configuration.userContentController.add(self, name: "finishLoading")
    webView.configuration.userContentController.add(self, name: "logout")
    webView.isHidden = true
    activityIndicator.isHidden = false

    if appDelegate.externalUrl == nil {
        webView.load(URLRequest(url: URL(string: "https://example.com")!))
    } else {
        deepLinkURL = self.appDelegate.externalUrl!
        let urlRequest = URLRequest(url: deepLinkURL!)
        self.webView.load(urlRequest)
        isFromDeepLing = true
        webView.isHidden = true
        activityIndicator.isHidden = false
        print(urlRequest)

    }
}

//when loading url finish call a js functions
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
    guard let dataForJS = userDefaults.string(forKey: "dataJs") else {
        self.webView.isHidden = false
        self.activityIndicator.isHidden = true
        return
    }

    if !isFromDeepLing {
        webView.evaluateJavaScript("handleNativeLogin('\(dataForJS)')") { (result, error) in
            self.webView.isHidden = false
            self.activityIndicator.isHidden = true
        }
    } else {
        if !isUsedDeepLink {
            webView.evaluateJavaScript("handleNativeLogin('\(dataForJS)')") { (result, error) in
            }
            webView.isHidden = true
            activityIndicator.isHidden = false
            DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
                let urlRequest = URLRequest(url: self.deepLinkURL!)
                self.webView.load(urlRequest)
                self.isUsedDeepLink = true
            }
        } else {
            self.webView.isHidden = false
            self.activityIndicator.isHidden = true
        }
    }
}

//segue to login screen and logout from smooch
func goToLoginScreen(){
    Smooch.logout {(error:Error?, userInfo:[AnyHashable : Any]?) in

    }
    userDefaults.removeObject(forKey: "data")
    performSegue(withIdentifier: "loginViewController", sender: self);
}

// check if token is valid . if not, go to login screen
func checkToken(){
    if let token = userDefaults.dictionary(forKey: "data")?["access_token"]{
        serverManager.checkToken(token: token as! String) { (code) in
            if(code == "200"){
                print("token is valid")
            }else if(code == "401"){
                print("token expierd")
                self.goToLoginScreen()
            }
        }
    }
}

// connect to smooch service , init and login
func initSmooch(){
    guard let appId = responseData["smoochAppId"] ,let userId = responseData["smoochUserId"], let smoochToken = responseData["smoochJWTToken"] else {
        chatBtnOutlet.isHidden = true
        return
    }
    Smooch.initWith(SKTSettings(appId: appId as! String)) { (error:Error?, userInfo:[AnyHashable : Any]?) in
        if(error == nil){
            print("smooch init success")
            Smooch.login(userId as! String , jwt: smoochToken as! String, completionHandler: { (error:Error?, userInfo: [AnyHashable : Any]?) in
                if(error == nil){
                    print("smooch user login success")
                }else{
                     print("smooch user login failed")
                }
            })
        }else{
             print("smooch init failed")
        }
    }
}

// listen to js event
func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) {
    if(message.name == "finishLoading"){
        print("finishLoading")

    }else if (message.name == "logout"){
        userDefaults.set(false, forKey: "isLoggedIn")
        self.goToLoginScreen()
    }
}

这里是我使用通用链接的 appDelegate：

 // MARK: - Deep Linking

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {

    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
        let url = userActivity.webpageURL else { return false }

    var viewController = UIViewController()

    let userDefaults = UserDefaults.standard
    let isLoggedIn = userDefaults.bool(forKey: "isLoggedIn")

    if url.path == "/login" || isLoggedIn == false {
        viewController = self.getDestinationLogin(for: url)
    } else {
        viewController = self.getDestinationMain(for: url)
    }
    externalUrl = url
    window?.rootViewController = viewController
    window?.makeKeyAndVisible()
    return (parseAppLinks(from: url) != nil)
}

 func getDestinationLogin(for url: URL) -> UIViewController {
    let storyboard = UIStoryboard(name: "Main", bundle: .main)
    let loginVC = storyboard.instantiateViewController(withIdentifier: "loginViewController") as? LoginViewController
    return loginVC!
}

func getDestinationMain(for url: URL) -> UIViewController {
    let storyboard = UIStoryboard(name: "Main", bundle: .main)
    let mainVC = storyboard.instantiateViewController(withIdentifier: "MainViewController") as? MainViewController
    let userDefaults = UserDefaults.standard
    userDefaults.set(true, forKey: "isLoggedIn")

    return mainVC!
}

private func parseAppLinks(from url: URL) -> String? {
   guard let components = URLComponents(url: url, resolvingAgainstBaseURL: true)  else { return .none }
   guard let urlString = components.queryItems?.first?.value else { return .none }

   return urlString
}
