Question

我正在尝试使用Firebase云消息传递来实现推送通知。我已经关注了来自https://firebase.google.com/docs/cloud-messaging/ios/client的firebase官方教程它在模拟器中工作，我得到我从firebase控制台发送的消息，但是当我尝试在设备中构建它时，它不会获得InstanceID令牌（FCM令牌）。

这是我的AppDelegate代码

没有什么可以改变的。我从firebase控制台设置了一条消息，以便以后交付，它完美运行.firebase控制台时间和我的iphone时间不匹配，这就是它没有立即发送消息的原因。

Firebase Cloud消息在模拟器中工作，但不在IOS设备上工作
