FCM 推送通知在 iOS 11 上不起作用

FCM Push notifications do not work on iOS 11

提问by Alexander Khitev

I use Firebase as a backend. I also use FCM as one of the provided features from Firebase. FCM worked well in iOS 10, but after switching to iOS 11, push notifications stopped coming to user devices, and I myself did not receive any push notifications sent from the cloud functions or the Notification section in the Firebase Console. How to fix this problem?

我使用 Firebase 作为后端。我还使用 FCM 作为 Firebase 提供的功能之一。FCM 在 iOS 10 中运行良好，但在切换到 iOS 11 后，推送通知停止发送到用户设备，我自己也没有收到任何从云功能或 Firebase 控制台中的通知部分发送的推送通知。如何解决这个问题？

Update:I sent several push notifications from Firebase Notifcations, but they do not come.

更新：我从 Firebase Notifcations 发送了几个推送通知，但他们没有来。

It appears that with FirebaseInstanceID 2.0.3 push notifications don't work. It helped me to set: pod 'FirebaseInstanceID', "2.0.0". Maybe in next version this will be fixed.

似乎 FirebaseInstanceID 2.0.3 推送通知不起作用。它帮助我设置：pod 'FirebaseInstanceID', "2.0.0"。也许在下一个版本中，这将被修复。

Please update your FCM pod

请更新您的 FCM pod

pod ‘Firebase/Messaging'

to the latest version, which is 2.0.6

到最新版本，即 2.0.6

Installing FirebaseInstanceID (2.0.6)
Installing FirebaseMessaging (2.0.6)

It should work with iOS 11+ devices.

它应该适用于 iOS 11+ 设备。

I read this topicand added this code application.registerForRemoteNotifications()to the AppDelegate method didFinishLaunchingWithOptionsand it worked, but unfortunately current users will not receive notifications until they are updated to the new version. Please see https://github.com/firebase/quickstart-ios/issues/327#issuecomment-331782299

我阅读了这个主题并将此代码添加application.registerForRemoteNotifications()到 AppDelegate 方法中didFinishLaunchingWithOptions并且它起作用了，但不幸的是，当前用户在更新到新版本之前不会收到通知。请参阅https://github.com/firebase/quickstart-ios/issues/327#issuecomment-331782299

Seems to be an issue with Firebase SDK where push notifications stop working after app relaunch or when killed. A work around for this was suggested:

似乎是 Firebase SDK 的一个问题，其中推送通知在应用重新启动或被终止后停止工作。建议解决此问题：

let deleteCount = UserDefaults.standard.integer(forKey: "oneTimeWorkaroundKey")
        if deleteCount == 0 {
            InstanceID.instanceID().deleteID { error in
                if let cError = error {
                    log("APNS: Error on delete: \(cError)")
                } else {
                    UserDefaults.standard.set(deleteCount + 1, forKey: "oneTimeWorkaroundKey")
                }
            }
        }
