我很难显示我从 FCM 通知控制台发送到我的设备的推送通知.我可以看到设备正在接收通知，因为我可以看到我发送的消息test8"
I am struggling to display my push notifications that I am sending to my device from the FCM notification console. I can see the device is receiving the notification because I can see the message I send "test8"
Connected to FCM.
%@ [AnyHashable("notification"): {
body = test8;
e = 1;
},
但不管我的应用是在前台还是后台，我都不会显示通知.
But it does not matter if my app is in the foreground or background I don't get the notification displayed.
我在 info.plist 中添加了必需的后台模式 - 应用下载内容以响应推送通知".我的证书是正确的，生成令牌没有问题.我的应用正在接收通知，但只是不显示它们.
I have added "Required background modes - App downloads content in response to push notifications" to the info.plist. My certificates are correct and I have no issue generating a token. My app is receiving the notifications but just not displaying them.

我一直在尝试自己研究和解决这个问题，但我遇到了问题.任何帮助或建议将不胜感激.
I having been trying to research and solve this issue on my own but I am having issues. Any help or suggestions would be greatly appreciated.
在didRegisterForRemoteNotificationsWithDeviceToken方法内部，添加如下代码:
Inside method didRegisterForRemoteNotificationsWithDeviceToken, add the following code:
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
var tokenString = ""
for i in 0..<deviceToken.length {
tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown)
print("tokenString: (tokenString)")
}
别忘了在Capabilities中启用Push Notifications.
