通用链接重定向到特定视图

Question

我很难理解通用 Link 的工作原理。首先，我尝试从 SceneDelegate 重定向到特定的 UIViewController（通用 link 工作，因为它将用户从电子邮件中的按钮单击重定向到我的应用程序），但它不起作用。我还注意到 URL 没有在 appDelegate 中处理，我不知道为什么。

这是 AppDelegate 中函数的片段：

func application(_ application: UIApplication,
                     continue userActivity: NSUserActivity,
                     restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool
    {
       print("am I even here ?")
        
        guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
                let incomingURL = userActivity.webpageURL,
              
                let components = NSURLComponents(url: incomingURL, resolvingAgainstBaseURL: true) else {
                return false
            }
            

            // Check for specific URL components that you need.
            guard let path = components.path,
            let params = components.queryItems else {
                return false
            }
           print("path = \(path)")

            if let userId = params.first(where: { [=10=].name == "_id" } )?.value,
                let token = params.first(where: { [=10=].name == "token" })?.value {
                print("_id = \(userId)")
                print("token = \(token)")
                return true

            } else {
                print("Either INDEX ARE MISSING")
                return false
            }

    }

来自 SceneDelegate 的片段：

func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
           // the url is going to be in userActivity.webpageURL
        print(userActivity.webpageURL)
        print(userActivity.webpageURL?.pathComponents[2])
        print(userActivity.webpageURL?.pathComponents[1])
        
        if (userActivity.webpageURL?.lastPathComponent != nil ) {
            
            let storyboard = UIStoryboard(name: "Main", bundle: nil)

            let vc = self.window?.rootViewController?.storyboard?.instantiateViewController(withIdentifier: "ViewController") as? ViewController
            //queryVC?.urlQueryId = queryId!
            self.window?.rootViewController?.present(vc!, animated: true, completion: nil)

        
          

            
            print("am I moving ?")

         
        }
    }

提前抱歉，我对 swift 和 IOS 总体上还是新手，感觉我陷入了一个循环。

ps：来自 SceneDelagate 打印的数据，我得到了两个参数和完整的 URL 以及参数。

谢谢，

好的，这已修复，从 ios 13 开始，如果您有场景委托，那么您应该在此处处理响应。我就是这样修复它的。

if (userActivity.webpageURL?.pathComponents[2] != nil)
        {
           
            let userId = userActivity.webpageURL?.pathComponents[1]
            let token = userActivity.webpageURL?.pathComponents[2]
           
            
             if self.window?.rootViewController?.presentedViewController != nil {
                 self.window?.rootViewController?.dismiss(animated: false, completion: nil)
                    }

            let Main =  self.window?.rootViewController?.storyboard?.instantiateViewController(withIdentifier: "ResetPassword") as? ResetPasswordViewController
            
            //Main.userIdentification = "fd"
            Main?.userIdFromUrl = userId
            Main?.UsertokenFromUrl = token
           // Main.userToken = "aa"
            
            Main?.modalPresentationStyle = .fullScreen
            self.window?.rootViewController?.present(Main!, animated: true, completion: nil)
            
            
        }
        else {print("doesn't contain")}

userIdFromUrl 和 UsertokenFromUrl 也是我在目标视图控制器中初始化的变量。我希望这对任何人都有帮助。很少有教程提到场景委托的使用，在阅读了十几个之后，我最终运行圈子里。
