Firebase Cloud Messaging AppDelegate Error

Ответ 1

Пример в документах Firebase устарел. Вот код для последних Xcode 8 и Swift 3:

import Firebase
import UserNotifications

class AppDelegate: UIResponder, UIApplicationDelegate {


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


        FIRApp.configure()

        if #available(iOS 10.0, *) {
            let authOptions : UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_,_ in })

            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self
            // For iOS 10 data message (sent via FCM)
            FIRMessaging.messaging().remoteMessageDelegate = self

        }

        application.registerForRemoteNotifications()

        return true
    }
}


@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 message ID.
        print("Message ID: \(userInfo["gcm.message_id"]!)")

        // Print full message.
        print("%@", userInfo)

    }

}

extension AppDelegate : FIRMessagingDelegate {
    // Receive data message on iOS 10 devices.
    func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
        print("%@", remoteMessage.appData)
    }
}

Ответ 2

Вам необходимо добавить следующие файлы в файл:

import Firebase
import FirebaseMessaging
import UserNotifications

Вам также нужен метод с именем tokenRefreshNotification, похожий на следующий:

func tokenRefreshNotification() {
    let fcmDeviceToken = FIRInstanceID.instanceID().token()
    // TODO: Send token to server
}

Для быстрого 2.0 добавить протокол FIRMessagingDelegate

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate{}
func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage){}

Ответ 5

Свифт 2.3 версии ответа Алексея будет:

if #available(iOS 10.0, *) {
            let authOptions: UNAuthorizationOptions = [.Alert, .Badge, .Sound]
            UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(authOptions, completionHandler: {_, _ in})

            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.currentNotificationCenter().delegate = self
            // For iOS 10 data message (sent via FCM)
            FIRMessaging.messaging().remoteMessageDelegate = self

        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(forTypes: [.Alert , .Badge, .Sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }

        application.registerForRemoteNotifications()

А..

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

    // Receive displayed notifications for iOS 10 devices.

    func userNotificationCenter(center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
        let userInfo = notification.request.content.userInfo
        // Print message ID.
        print("Message ID: \(userInfo["gcm.message_id"]!)")

        // Print full message.
        print("%@", userInfo)

    }

}

extension AppDelegate : FIRMessagingDelegate {
    // Receive data message on iOS 10 devices.
    func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage) {
        print("%@", remoteMessage.appData)
    }
}
