iOS FCM消息传递未调用

Question

我想使用FCM将通知和数据消息发送到iOS设备。

都可以正常工作，但是由于某种原因，委托方法messaging didReceiveRemoteMessage从未被调用。因此，当应用在前景中时，我无法收到数据消息...我在数据旁边尝试了有没有通知块的情况。因此，我发送的消息看起来像这样：

{'message': {
    'token': 'mytokenstandshere',
    'notification': {
        'body': 'message',
        'title': 'title'},
    'data': {
        'datafield': 'datavalue',
        'datafield2': 'datavalue2'}
}}

我尝试了所有可能性(没有通知，没有数据，两者都(。通知没有问题，但是数据块没有出现在干净的数据消息中。

我只想在iOS 11 上运行此操作。但是我什至尝试了Google的文档中iOS 9和10的零件。

。

这是我的AppDelegate：

@
UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate {
    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        Hardware.start()
        Preferences.initDefaults()
        FirebaseApp.configure()
        Messaging.messaging().delegate = self
        Messaging.messaging().shouldEstablishDirectChannel = true
        UNUserNotificationCenter.current().delegate = self
        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })
        application.registerForRemoteNotifications()

        return true
    }
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        print("new Token: (fcmToken)")
        Messaging.messaging().subscribe(toTopic: TOPIC_ALL_MESSAGES)
        NotificationSettingsListener.start()
    }
    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
        print("Got a remote")
    }
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        completionHandler(UIBackgroundFetchResult.newData)
    }
}
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        let userInfo = notification.request.content.userInfo
        // Print full message.
        print(userInfo)
        // Change this to your preferred presentation option
        completionHandler([.alert])
    }
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
                                withCompletionHandler completionHandler: @escaping () -> Void) {
        let userInfo = response.notification.request.content.userInfo
        // Print full message.
        print(userInfo)
        completionHandler()
    }
}

Answer 1

我没有看到：

application(_: didReceiveRemoteNotification: fetchCompletionHandler:)

我相信这是处理所必需的。参考

Answer 2

请确保您必须在 AppDelegate.m

中分配firebase消息委托

[FIRMessaging messaging].delegate = self;
