所以这是我第一次尝试在应用上实施通知时..我设法收到它并在userInfo中看到它，但我没有收到它作为我的顶部提醒从Firebase的云消息传递中接收它。

可能有冗余代码......不是真的必要
来自控制台：
整条消息[AnyHashable（“data”）：{“duration”：“1346”，“updated_at”：“2018-05-04 18:53:54”，“status_type”：2，“conversation_id”：“ 8“，”owner_id“：13，”status_name“：”读取“，”message_token“：”2018050421535268819“，”created_at“：”2018-05-04 18:53:54“，”message_id“：156，”url “：”https://voicemo.site/media/files/8/201805042153526881915613.amr“}，AnyHashable（”push_id“）：ios_fIpMjYVprDSxrp3LWbV4QOIms452WUsT，AnyHashable（”gcm.message_id“）：0：1525460034407947％cef2e812cef2e812，AnyHashable（” notification_type“）：message，AnyHashable（”params“）：{”color“：”＃009687“，”conversation_id“：”8“，”subject“：”new voice message“，”sound“：”default“，” icon“：”https://voicemo.site/media/photos/users/img_2c9b5.jpg“，”title“：”CabuZZ“}，AnyHashable（”aps“）：{ “content-available”= 1; }]
答案 0 :(得分：1)
1）当应用处于后台时：
当应用在后台时显示通知的正确格式在aps字典中为：
{
"aps": {
"alert": {
"title": "",
"subtitle": "",
"body": “”
},
"badge": 1,
"sound": "default",
"content-available": 1,
}
// Other data here...
}
因此，在您的情况下，将aps密钥的有效负载更新为：
"aps": {
"alert": {
"title": "CabuZZ",
"body": “new voice message”
},
"badge": 1,
"sound": "default",
"content-available": 1,
}
2）当应用处于前台时：
您将在以下功能中收到userInfo中的数据，您需要手动显示和处理视图。当app位于前台时，iOS不会显示视图。
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
// Handle your view here (app in foreground)
}
