                  问题描述

                  我已通过 FCM 在我的两个相关应用中成功实现推送通知,并尝试实现一些逻辑以在收到通知时增加徽章编号.

                  I have successfully implemented push notifications in my two related apps via FCM and while trying to implement some logic to increment badge number on receiving the notification.

                  我意识到 didReceiveRemoteNotificationdelegate 方法根本没有被调用,因为我没有得到任何打印结果,但我确实从 willPresent 通知didReceive 响应.所以在 didFinishLaunchingWithOptions 中设置 UIApplication.shared.applicationIconBadgeNumber 没有效果,但是在里面设置 didReceive response 可以.

                  I realized that didReceiveRemoteNotificationdelegate method is not called at all as I don't get any prints out of it, but I do get prints from willPresent notificationand didReceive response. So setting UIApplication.shared.applicationIconBadgeNumber in didFinishLaunchingWithOptionshas no effect, but setting in it didReceive responsedoes.

                  按照文档 didReceiveRemoteNotification 应该被调用,但是当通知到达时我从来没有打印出来.

                  Following the documentation didReceiveRemoteNotification should be called but I never get prints out of it when a notification arrives.

                  我尝试将整个 didReceiveRemoteNotification 方法注释掉,并且通知仍然传递.

                  I tried commenting out the whole didReceiveRemoteNotificationmethod and notifications are still delivered.

                  为什么会这样?我想我真的不明白谁在这个设置中处理消息.你能帮我澄清一下吗?

                  Why is it so? I guess I didn't really understand who's handling messaging in this set up. Can you please help me clarifying it?

                  AppDelegate 方法:

                  我终于找到了解决方案.警报需要"content_available": true 在从 App2 到 App1 的帖子发送功能的警报定义中设置,否则会传递通知但不调用didReceiveRemoteNotification",您不能使用userInfo"'.希望这对其他人有所帮助,因为我没有找到有关此问题的太多信息.如果您使用 Postman 或类似工具设置通知,请在此处查看 didReceiveRemoteNotification 函数不使用 FCM 通知服务器调用,因为这是我在这个问题上找到的唯一帖子并解决了我的问题.感谢@Ranjani 尝试帮助我.

                  I finally found the solution. Alert needs"content_available": true to be set in the alert definition from the post sending funtion from App2 to App1 or else notifications get delivered but 'didReceiveRemoteNotification` is not called and you can't use 'userInfo'. Hope this will help others as I haven't found much info about this problem. If you're setting the notification with Postman or similars check here didReceiveRemoteNotification function doesn't called with FCM notification server as that's the only post I found on this problem and solved mine. Thanks to @Ranjani for trying helping me.

                  let postParams: [String : Any] = [
                                  "to": receiverToken,
                                  "notification": [
                                      "badge" : 1,
                                      "body": body,
                                      "title": title,
                                      "subtitle": subtitle,
                                      "sound" : true, // or specify audio name to play
                                      "content_available": true, // this will call didReceiveRemoteNotification in receiving app, else won't work
                                      "priority": "high"
                                  ],
                                  "data" : [
                                      "data": "ciao",
                              ]
                                  ]
