SwiftUI 2 Firebase 推送通知

Question

因此，我正在使用 SwiftUI 2 和新的应用程序生命周期构建 iOS 应用程序，尝试实现 AppsDelegate 和 Firebase 推送通知

\n

这是我的代码示例

\n

import SwiftUI\n\n@main\nstruct App: App {\n    \n    @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate\n    \n    var body: some Scene {\n        WindowGroup {\n            ContentView().environmentObject(AppSettings())\n        }\n    }\n}\n

和应用程序委托

import Firebase\nimport FirebaseMessaging\nimport UserNotifications\nimport Foundation\nimport UIKit\nclass AppDelegate: NSObject {\n    \n    let gcmMessageIDKey = "gcm.message_id"\n    \n    private func setupFirebase(application: UIApplication) {\n        FirebaseApp.configure()\n\n        if #available(iOS 10.0, *) {\n            // For iOS 10 display notification (sent via APNS)\n            UNUserNotificationCenter.current().delegate = self\n\n            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]\n            UNUserNotificationCenter.current().requestAuthorization(\n                options: authOptions,\n                completionHandler: {_, _ in })\n        } else {\n            let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)\n            application.registerUserNotificationSettings(settings)\n        }\n        Messaging.messaging().delegate = self\n        application.registerForRemoteNotifications()\n    }\n    \n}\n\nextension AppDelegate: UIApplicationDelegate {\n    \n    func application(_ application: UIApplication,\n                     didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {\n        setupFirebase(application: application)\n        return true\n    }\n    \n}\n\nextension AppDelegate: MessagingDelegate {\n    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {\n        print("Firebase registration token: \\(fcmToken)")\n    }\n}\n\n@available(iOS 10, *)\nextension AppDelegate: UNUserNotificationCenterDelegate {\n    \n    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {\n        let userInfo = notification.request.content.userInfo\n        \n        // With swizzling disabled you must let Messaging know about the message, for Analytics\n        // Messaging.messaging().appDidReceiveMessage(userInfo)\n        \n        // Print message ID.\n        \n        if let messageID = userInfo[gcmMessageIDKey] {\n            print("Message ID: \\(messageID)")\n        }\n        \n        // Print full message.\n        // print(userInfo)\n        \n        completionHandler([.banner, .badge, .sound])\n    }\n    \n    func userNotificationCenter(_ center: UNUserNotificationCenter,\n                                didReceive response: UNNotificationResponse,\n                                withCompletionHandler completionHandler: @escaping () -> Void) {\n        let userInfo = response.notification.request.content.userInfo\n        // Print message ID.\n        \n        if let messageID = userInfo[gcmMessageIDKey] {\n            print("Message ID: \\(messageID)")\n        }\n        \n        // Print full message.\n        print(userInfo)\n        \n        completionHandler()\n    }\n    \n}\n

但是当我\xe2\x80\x99m 测试来自 firebase 控制台的通知时，它没有出现。

2022 年 12 月更新

当写这个答案时，Firebase 允许您禁用 swizzling，但还有几个其他区域必须更新才能使其工作。

Firebase 现已删除这些附加要求，您应该相应地更新您的实现。

SwiftUI 应用程序应使用 UIApplicationDelegateAdaptor 或 NSApplicationDelegateAdaptor 属性包装器来提供与适当的应用程序委托协议相对应的类型。

您应该仔细检查文档，因为 SO 上的帖子很容易就会过时。

执行

我能够让你的代码工作。我认为 Firebase 在调整AppDelegate.

如果您通过将密钥添加FirebaseAppDelegateProxyEnabled到您的Info.plist、将其设为 aBoolean并将其设置为 来禁用混合NO。

然后，AppDelegate您需要添加以下内容，以便它向 Firebase 注册 APNS 令牌：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    Messaging.messaging().apnsToken = deviceToken
}

为了使 Firebase Cloud Messaging 正常工作，需要在 APNS 令牌与其令牌之间建立链接。如果未建立链接，则您将无法发送消息。

您可能还想设置一个消息传递委托，这允许您监视令牌刷新。这可以通过遵守消息传递委托协议来完成，更多信息可以在此处找到。
