我一直致力于在我的应用程序中包含动态链接。我已经对其进行了设置，以便可以正确生成并正确接收链接，但它们仅在应用程序打开并在后台运行时才有效。如果应用程序完全关闭，该链接将仅打开该应用程序。即使我在 didFinishLaunchingWithOptions 方法中返回 TRUE，它看起来也没有调用 AppDelegate 中的 continueUserActivity 方法。我读过，我应该在 didFinishLaunchingWithOptions 方法中获取传入的 URL，但可用的答案不起作用并且已经过时，所以我希望有人知道。
这是代码：
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate{
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FirebaseApp.configure()
return true
}
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
if let incomingURL = userActivity.webpageURL {
let linkHandled = DynamicLinks.dynamicLinks().handleUniversalLink(incomingURL) { (dynamicLink, error) in
guard error == nil else {
print(error!.localizedDescription)
return
}
if let dynamicLink = dynamicLink {
self.handleIncomingDynamicLink(dynamicLink)
} else {
print("Something went wrong")
}
}
if linkHandled {
return true
} else {
return false
}
}
return false
}
func handleIncomingDynamicLink(_ dynamicLink: DynamicLink) {
guard let url = dynamicLink.url else {
print("No incoming link")
return
}
print("Link is: \(url)")
SystemManager.sharedInstance.setDeepLinkTrip(tripKey: deepLinkParser(link: url))
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewController = storyboard.instantiateViewController(withIdentifier: "RootVC")
self.window?.rootViewController = initialViewController
}
那么，现在应用程序冷启动时，如何才能正确打开链接呢？感谢您的帮助:)
编辑：我已经更新了我的应用程序以使用 SceneDelegate，所有其他答案都建议这样做，但它仍然不起作用。如果在后台运行，它仍然会打开动态链接，但否则不会打开它们。看起来没有任何链接发送到该应用程序。我找不到任何 userActivity、urlContexts 等。
这是新的相关代码：
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
//I read that this function should be handling the link when it is clicked while the app is dead, but nothing works. Basically this checks that the user is logged in (always is), then looks for a link.
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
self.scene(scene, openURLContexts: connectionOptions.urlContexts)
guard let _ = (scene as? UIWindowScene) else { return }
if Auth.auth().currentUser != nil {
if let userActivity = connectionOptions.userActivities.first {
self.scene(scene, continue: userActivity)
} else {
self.scene(scene, openURLContexts: connectionOptions.urlContexts)
}
if let userActivity = connectionOptions.userActivities.first {
if let incomingURL = userActivity.webpageURL {
_ = DynamicLinks.dynamicLinks().handleUniversalLink(incomingURL) { (dynamicLink, error) in
guard error == nil else { return }
if let dynamicLink = dynamicLink {
self.handleIncomingDynamicLink(dynamicLink)
} else {
print("Something went wrong")
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewController = storyboard.instantiateViewController(withIdentifier: "RootVC")
self.window?.rootViewController = initialViewController
}
}
}
} else {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewController = storyboard.instantiateViewController(withIdentifier: "RootVC")
self.window?.rootViewController = initialViewController
}
}
}
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
if let url = URLContexts.first?.url {
_ = DynamicLinks.dynamicLinks().handleUniversalLink(url) { (dynamicLink, error) in
guard error == nil else { return }
if let dynamicLink = dynamicLink {
//your code for handling the dynamic link goes here
self.handleIncomingDynamicLink(dynamicLink)
}
}
}
}
func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
if let incomingURL = userActivity.webpageURL {
_ = DynamicLinks.dynamicLinks().handleUniversalLink(incomingURL) { (dynamicLink, error) in
guard error == nil else {
print(error!.localizedDescription)
return
}
if let dynamicLink = dynamicLink {
self.handleIncomingDynamicLink(dynamicLink)
} else {
print("Soemthing went wrong")
}
}
}
}
