问题描述
我已将 Firebase DeepLink/DynamicLinks/UniversalLink 集成到我们的应用中。当 app is running 或 background/foreground state 时，Deep Links 工作没有问题。但是，当应用程序处于 not running 或处于 killed/terminated 状态时，应用程序将启动，但不会调用或初始化任何触发器方法。就好像它只触发 URL Scheme。因此，结果是，我无法获取被点击的深层链接的数据，这是一个大问题。
在 didFinishLaunchingWithOptions: 中，launchOptions 始终为零，因此 launchOptions[.url] 为零
func application(_ application: UIApplication,didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool
并且 open url:options: 不会触发
func application(_ app: UIApplication,open url: URL,options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool
当然这个continue userActivity:restorationHandler:不会触发
func application(_ application: UIApplication,continue userActivity: NSUserActivity,restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool
所以，我只能在没有捕获数据的情况下启动应用程序。任何解决方法或建议表示赞赏。谢谢！
解决方法
我花了一些时间来解决这个问题。在尝试了一系列解决方法后，有效的解决方案是使用 Apple's App Structure 迁移到新的 SceneDelegate。
从终止状态处理DeepLink，需要配置这个函数：
var window: UIWindow?
func scene(_ scene: UIScene,willConnectTo session: UISceneSession,options connectionOptions: UIScene.ConnectionOptions) {
if let userActivity = connectionOptions.userActivities.first,let url = userActivity.webpageURL {
DynamicLinks.dynamicLinks().handleUniversalLink(url) { dynamicLink,error in
guard let dynamicLink = dynamicLink,let url = dynamicLink.url else { return }
parseDynamicLink(fromURL: url)
}
}
guard let windowScene = (scene as? UIWindowScene) else { return }
// Initialize UIWindow
window = UIWindow(windowScene: windowScene)
window?.rootViewController = YOUR_ROOT_VIEW_CONTROLLER
window?.makeKeyAndVisible()
}
处理 UIApplication 等效的场景委托的其他部分：
func scene(_ scene: UIScene,continue userActivity: NSUserActivity) {
guard let url = userActivity.webpageURL else { return }
DynamicLinks.dynamicLinks().handleUniversalLink(url) { dynamicLink,error in
guard let dynamicLink = dynamicLink,let url = dynamicLink.url else { return }
parseDynamicLink(fromURL: url)
// launch dynamic link code here...?
}
}
func scene(_ scene: UIScene,openURLContexts URLContexts: Set<UIOpenURLContext>) {
guard let urlContext = URLContexts.first else { return }
if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: urlContext.url) {
guard let url = dynamicLink.url else { return }
parseDynamicLink(fromURL: url)
}
}
如果您打算进行迁移，请确保正确配置您的 Info.plist 的 Application Scene Manifest，然后在此处设置您的场景配置：
func application(_ application: UIApplication,configurationForConnecting connectingSceneSession: UISceneSession,options: UIScene.ConnectionOptions) -> UISceneConfiguration {
return UISceneConfiguration(name: "Default Configuration",sessionRole: connectingSceneSession.role)
}
您的 Application Scene Manifest 应如下所示：
<?xml version="1.0" encoding="UTF-8"?>
