为什么在 iOS 11.4 版本中无法获取设备令牌值和 FCM 令牌值？

Question

I am developing message communication through FCM.

But there's a problem. On iPhone 6 , version 12.4 , you can normally get device tokens and FCM values.

However, 11.4 does not get a device token value, nor does it get an FCM token value. I don't know what the problem is.

On iPhone 12.4, FCM token values are received here. And the iOS version is the same.

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

        Log.Info("Registration succeeded!")

        Auth.auth().setAPNSToken(deviceToken, type: AuthAPNSTokenType.sandbox)
        Messaging.messaging().apnsToken = deviceToken
        InstanceID.instanceID().instanceID { (result, error) in
            if let error = error {
                Log.Error("Error fetching remote instance ID: \(error)")
            } else if let result = result {
                Log.Info("Remote instance ID token: \(result.token)")
                LocalStorage.set(result.token, "dacDeviceToken")
            }
        }
        Messaging.messaging().shouldEstablishDirectChannel = true
    }

However, you can't see logs of FCM Token or device token values anywhere on iPhone 11.4. How can you solve this problem?

Answer 1

@Starsky was right. This was a bug, and after I erased my app and restarted the device, the problem was solved.
