ios - iOS 设备上未收到 Firebase 推送通知。虽然控制台记录了消息，但它在设备上收到

问题描述

我根据 Firebase 控制台中提供的说明创建了一个示例 ios 应用程序，以在 ios 设备上接收云消息。通知消息从控制台发送并打印在应用程序控制台上。但是即使在给予必要的许可后，设备也不会收到推送通知。

我正在使用 swift 3 和 xCode 10.3 版。在 Firebase 控制台中注册了应用程序，并通过应用程序接收所需的 FCM 令牌并添加以向设备发送测试消息。尝试通过控制台发送大量消息，但设备上均未显示。它显示消息正在控制台上成功发送。

以下是我为接收推送通知而编写的 AppDelegate.swift 文件。

import UIKit
import UserNotifications
import Firebase
import FirebaseMessaging
import FirebaseInstanceID

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    let gcmMessageIDKey = "gcm.message_id"

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

        if #available(iOS 10.0, *) {

            FirebaseApp.configure()           

            Messaging.messaging().delegate = self
            Messaging.messaging().shouldEstablishDirectChannel = true

            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_, _ in })
        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }


        // request permission from user to send notification
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound], completionHandler: { authorized, error in
            if authorized {
                DispatchQueue.main.async(execute: {
                    application.registerForRemoteNotifications()
                })
            }
            else{
                print("Notification access denied")
            }
        })
        return true
    }


    // [START receive_message]
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {

        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }

        print(userInfo)
    }

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }

        print(userInfo)

        completionHandler(UIBackgroundFetchResult.newData)
    }

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Unable to register for remote notifications: \(error.localizedDescription)")
    }


    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        Messaging.messaging().apnsToken = deviceToken
        print("APNs token retrieved: \(deviceToken)")


    }

}

@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {

    // Receive displayed notifications for iOS 10 devices.
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        let userInfo = notification.request.content.userInfo

        print(userInfo)
         print("Message ID: \(userInfo["gcm.message_id"]!)")
        completionHandler(UNNotificationPresentationOptions.alert)

    }

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
                                withCompletionHandler completionHandler: @escaping () -> Void) {
        let userInfo = response.notification.request.content.userInfo

        print("Do what ever you want")
        // Print full message.
        print("tap on on forground app",userInfo)


        completionHandler()
    }
}

extension AppDelegate : MessagingDelegate {

    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        print("Firebase registration token: \(fcmToken)")
        Messaging.messaging().subscribe(toTopic: "/topics/nutriewell_live")
        Messaging.messaging().shouldEstablishDirectChannel = true

    }

    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
        print("Received data message: \(remoteMessage.appData)")
    }


}

我希望在 ios 设备上收到推送通知，但我没有收到任何通知。我得到以下输出，它与从控制台发送的通知消息一起打印。

我可以在这里获得任何帮助吗？

解决方案

有两种方式接收通知：

  1. 当应用程序关闭/不活动并且您在 didFinishLaunchingWithOptions 中获得有效负载时：

  2. 当应用程序打开/活动且当前可见时，您将在 didReceiveRemoteNotification 中获得有效负载：

当您的应用程序关闭时，iOS 会处理显示通知（如果未开发通知扩展程序）并在您点击它时启动您的应用程序。

如果您的应用程序已打开，您必须注意显示此通知或忽略它。

这是官方文档所说的：

当本地和远程通知不是由您的应用程序或用户直接处理时，它们会显示在通知中心，以便以后查看。使用 共享UNUserNotificationCenter对象的getDeliveredNotificationsWithCompletionHandler:方法获取仍在通知中心显示的通知列表。如果您发现任何现在已过时且不应向用户显示的通知，您可以使用 removeDeliveredNotificationsWithIdentifiers:方法删除它们。
