深度链接仅在应用正在运行时才有效

Question

我有一个应用程序，当用户与其他用户共享应用程序中的特定内容时，它使用深层链接导航到页面。当第二个用户已经运行应用程序时，这是有效的，但如果应用程序没有运行，它只是打开应用程序并保留在主屏幕上。我知道我一定在这里错过了一些非常简单的东西，但我就是想不通，在谷歌上找不到任何关于这个问题的答案。

我在应用程序委托中的代码.swift：

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
        let urlPath : String = url.path as String!
        let urlHost : String = url.host as String!
        let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        if(urlHost != "example.com")
        {
            print("Call Not From Correct Host. Not Continuing...")
            return false
        }
        if(urlPath == "/articles"){
            let article: ArticleDetailsViewController = mainStoryboard.instantiateViewController(withIdentifier: "ArticleDetailsViewController") as! ArticleDetailsViewController
            self.window?.rootViewController = article
        } 
        self.window?.makeKeyAndVisible()
        return true
    }
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        return true
    }

Answer 1

这是

正确的行为。你应该在appliction(_: didFinishLaunchingWithOptions:)处理它

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    if let url = launchOptions[.url] as? URL, let annotation = launchOptions[.annotation] {
        return self.application(application, open: url, sourceApplication: launchOptions[.sourceApplication] as? String, annotation: annotation)
    }
    return true
}

Answer 2

如果您使用的是 sceneDelegate，scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions)函数将在终止状态后启动应用程序时起作用。

用于深度链接的 url 将在 connectionOptions.urlContext 中提供

 func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    navigateToDeepLinkScreen(urlContexts: connectionOptions.urlContexts)
}

Answer 3

对于 Swift4.2

if launchOptions != nil{
        let launch = launchOptions![UIApplicationLaunchOptionsKey.userActivityDictionary]! as! Dictionary <String,Any>
        if ((launch["UIApplicationLaunchOptionsUserActivityKey"]! as! NSUserActivity).webpageURL != nil){
            if defaults.bool(forKey: DEFAULTS_IS_FIRST_START){
                print((launch["UIApplicationLaunchOptionsUserActivityKey"]! as! NSUserActivity).webpageURL)
            }
        }
    }

Answer 4

func application(_ application: UIApplication,
                 didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    if let url = launchOptions?[.url] as? URL {
        return handleWidgetUrl(url)
    }
    return true
}
// Custom function to handle url and do some actions
private func handleWidgetUrl(_ url: URL) -> Bool {}

Answer 5

对于SceneDelegate：

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    /* some stuff */
    for activity in connectionOptions.userActivities {
        if let url = activity.webpageURL {
            // handle
        }
    }
}
