在我的设备上没有收到通知，只是在控制台中

Question

我执行以下步骤以在我的设备上接收通知：

1. 在 Xcode/功能 中激活推送通知。
2. 在我的开发者帐户上激活通知，并将 .p12 文件添加到 Firebase 控制台。

我在 xcode 控制台中收到通知，但我的设备上不会显示任何内容。这是我的代码：

import UIKit
import Firebase
import Vox
import FirebaseMessaging
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    let gcmMessageIDKey = "gcm.message_id"
    var responseData : String!

    func registerForPushNotifications() {
        UNUserNotificationCenter.current() 
            .requestAuthorization(options: [.alert, .sound, .badge]) { 
                granted, error in
                print("Permission granted: (granted)") 
        }
    }
    func getNotificationSettings() {
        UNUserNotificationCenter.current().getNotificationSettings { settings in
            print("Notification settings: (settings)")
            guard settings.authorizationStatus == .authorized else { return }
            DispatchQueue.main.async {
                UIApplication.shared.registerForRemoteNotifications()
            }
        }
    }
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        FirebaseApp.configure()
        Messaging.messaging().shouldEstablishDirectChannel = true
        Messaging.messaging()
        Messaging.messaging().delegate = self
        if #available(iOS 10.0, *) {
            UNUserNotificationCenter.current().delegate = self
            UNUserNotificationCenter.current()
                .requestAuthorization(options: [.alert, .sound, .badge]) {
                    [weak self] granted, error in
                    print("Permission granted: (granted)")
                    guard granted else { return }
                    self?.getNotificationSettings()
            }
        }
        else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }
        application.registerForRemoteNotifications()
        registerForPushNotifications()
        return true
    }
//for receive group messaging
    func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
        Messaging.messaging().subscribe(toTopic: responseData)
    }
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
        Messaging.messaging().appDidReceiveMessage(userInfo)
        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: (messageID)")
        }
        print(userInfo)
    }
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
         Messaging.messaging().appDidReceiveMessage(userInfo)
        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
        ) {
        let tokenParts = deviceToken.map { data in String(format: "%02.2hhx", data) }
        let token = tokenParts.joined()
        print("Device Token: (token)")
    }
}
extension AppDelegate : MessagingDelegate {
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        print("Firebase registration token: (fcmToken)")
    }
    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
        print("Received data message: (remoteMessage.appData)")
    }
}
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        let userInfo = notification.request.content.userInfo
         Messaging.messaging().appDidReceiveMessage(userInfo)
        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: (messageID)")
        }
        print(userInfo)
        completionHandler([.alert])
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
                                withCompletionHandler completionHandler: @escaping () -> Void) {
        let userInfo = response.notification.request.content.userInfo
        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: (messageID)")
        }
        print(userInfo)
        completionHandler()
    }
}

我的代码有什么问题?!?

Answer 1

我不明白你如何在火力基地
中发送APNs令牌您可以逐步
重新检查指南
https://firebase.google.com/docs/cloud-messaging/ios/client如果我有问题，通常我会制作空项目并设置(任何库(干净
在您的情况下，我没有看到您如何将设备令牌 (APN( 发送到 Firebase
你有功能

func application(
        _ application: UIApplication,
        didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data
        ) {
        let tokenParts = deviceToken.map { data in String(format: "%02.2hhx", data) }
        let token = tokenParts.joined()
        print("Device Token: (token)")
    }

在指南中，我看到此示例，您不会像这样发送令牌

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

也许你还有其他问题。
例如，如果应用程序位于前台，则默认行为不显示任何警报或横幅。
