ios - 当我从Scheme Url(Swift项目)启动应用程序时，openURL没有被调用

Question

当我通过 myapp://param1=abc 打开应用程序时，不会调用 open url 函数。

我已经添加了函数 didFinishLaunchingWithOptions 和 willFinishLaunchingWithOptions 使其成为 true，正如 Apple 文档所述，但它仍然没有被调用。应用程序完美打开，但未调用函数 open url 我无法获取 param1

这是我的 AppDelegate 文件:

class AppDelegate: UIResponder, UIApplicationDelegate  {

    func application(_ application: UIApplication,
                     didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        return true
    }

    func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        return true
    }

    func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        // Here doesn't come! :(
        return true
    }


    // MARK: UISceneSession Lifecycle


    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        // Called when a new scene session is being created.
        // Use this method to select a configuration to create the new scene with.
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
        // Called when the user discards a scene session.
        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
    }
}

知道会发生什么吗？

谢谢!

openUrl的签名AppDelegate中的方法已更新为，

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    return true
}

您需要添加您的urlScheme在项目设置的信息选项卡下的URL类型中，即

对于 Swift-5 和 iOS-13:

在 SceneDelegate.swift文件，您需要实现以下方法来处理 urlSchemes ，即

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    print(URLContexts)
}
