FCM推送通知在iOS 11上无法工作

我需要处理推送通知，这在较低版本的iOS中已完成，但在iOS 11中从未收到任何推送通知。我正在使用Firebase Cloud Messaging。如果有人有解决方案，请分享。

问题似乎出在以下方面：

FirebaseInstanceID版本低于1.0.9
FirebaseInstanceID版本在2.0.1 - 2.0.3之间

请将您的pod文件设置如下：

对于Swift 2.3和Xcode 8：（安装FirebaseInstanceID v1.1.0）

pod 'Firebase/Core', '3.8.0'
pod 'Firebase/Messaging'

对于Swift 3和Xcode 9：

pod 'Firebase/Core'
pod 'Firebase/Messaging'
pod 'FirebaseInstanceID', "2.0.0

我不想升级到 FirebaseInstanceID 2.0.0 来解决这个问题，因为我只想使用 Swift 2.3。

我曾经遇到过同样的问题，原因是在 Firebase 控制台中缺少了我的 APN 配置。
