ios - Swift 4：如果在 Deep Link 中有参数，则转到另一个屏幕

Question

介绍
我还是新手使用 Swift，现在，我有一个使用 Swift 的项目，而不是开发表单开始只是自定义应用程序。

问题
现在我想用参数创建深度链接。因此，我尝试遵循互联网上的一些教程，例如：[https://medium.com/wolox/ios-deep-linking-url-scheme-vs-universal-links-50abd3802f97] 和 [https://www .swiftdevcenter.com/custom-url-scheme-deep-link-ios-13-and-later-swift-5/] 但不起作用。

TRY TO DO
我想如果 App 检测到 Deep Link 有参数，App 将转到另一个页面并显示该参数。

在场景委托中添加此代码

类 SceneDelegate: UIResponder, UIWindowSceneDelegate {

var window: UIWindow?


func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
    // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
    // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
    guard let _ = (scene as? UIWindowScene) else { return }
}

func sceneDidDisconnect(_ scene: UIScene) {
    // Called as the scene is being released by the system.
    // This occurs shortly after the scene enters the background, or when its session is discarded.
    // Release any resources associated with this scene that can be re-created the next time the scene connects.
    // The scene may re-connect later, as its session was not necessarily discarded (see `application:didDiscardSceneSessions` instead).
}

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    
    if let url = URLContexts.first?.url{
      print(url)
      let urlStr = url.absoluteString //1
      // Parse the custom URL as per your uses, this will change as per requirement
      let component = urlStr.components(separatedBy: "=") // 2
      if component.count > 1, let productId = component.last { // 3
        self.pushToProductDetailSceen(productId: productId) // 4
      }
    }
}

func pushToProductDetailSceen(productId: String)
{
    
}

func sceneDidBecomeActive(_ scene: UIScene) {
    // Called when the scene has moved from an inactive state to an active state.
    // Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.
}

func sceneWillResignActive(_ scene: UIScene) {
    // Called when the scene will move from an active state to an inactive state.
    // This may occur due to temporary interruptions (ex. an incoming phone call).
}

func sceneWillEnterForeground(_ scene[![enter image description here][1]][1]: UIScene) {
    // Called as the scene transitions from the background to the foreground.
    // Use this method to undo the changes made on entering the background.
}

func sceneDidEnterBackground(_ scene: UIScene) {
    // Called as the scene transitions from the foreground to the background.
    // Use this method to save data, release shared resources, and store enough scene-specific state information
    // to restore the scene back to its current state.
}

}

只需将这条线放在 safari 中就可以了。
