即使在注册 fcm 令牌后也未在设备上收到通知 ios
not recieving notification on device even after registering for fcm token ios
下面是我的 appdelegate（我正在使用 Swift 3）。我成功获得了 fcm 令牌和 apns 令牌。设备上仍未显示通知。有人可以帮忙吗？

-> I was also suffer from this problem. I show your code. It is look perfect.But you have to check some point like...
1. Select Project (From Project Navigator)->Select Capabilities->On Push notification.
2. Your google plist file must be correct.
3. all things are done then run your latest application in ios device and then closed application.Even Removed from background.(If your application are in background then you can not show notification and most important you can not see notification in simulator.)
