Question

如果节点成功在Firebase中进行了更改，我已经从云功能发送了通知，但是即使我发送了多个通知，徽章编号也始终显示（1）。

我在云函数中的代码（打字稿）：

import * as functions from 'firebase-functions';
import admin = require('firebase-admin');
admin.initializeApp();
exports.sendPushNotificationToUpdate = functions.database.ref('/orders/{Id}/OrderStatus').onWrite((snapshot, context) => {
    let status = snapshot.after.val();
    console.log('status : ' + status);
    if (status != 'Done' && status != 'Rejected') {
        return null;
    }

    else {
        const Id = context.params.Id;

        console.log('id : ' + Id);

        return admin.database().ref('/orders/' + Id).once('value').then(function (snap) {
            const tokenId = snap.val().tokenId;
            console.log('tokenId : ' + snap.val().tokenId);
            let payload = {
                notification: {
                    title: 'my App',
                    body: '',
                    badge: '1',
                    sound: 'default',
                }
            }
            if (status == 'Done') {
                payload = {
                    notification: {
                        title: 'My App',
                        body: 'your order is done',
                        badge: '1',
                        sound: 'default',
                    }
                }


            }
            else if (status == 'Rejected') {
                payload = {
                    notification: {
                        title: 'My App',
                        body: 'your order is rejected',
                        badge: '1',
                        sound: 'default',
                    }
                }

            }
            return admin.messaging().sendToDevice(tokenId, payload).then(response => {
                console.log('update respose');
                console.log(response);
            });
        });
    }


});

我在Xcode中的代码（快速）：

 func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
       let userInfo = response.notification.request.content.userInfo
        print("tap on on forground app",userInfo)
        Messaging.messaging().appDidReceiveMessage(userInfo)
        let content = response.notification.request.content
        let badgeNumber = content.badge as! Int
        UIApplication.shared.applicationIconBadgeNumber  =  badgeNumber + 1

        completionHandler()
          let actionIdentifier = response.actionIdentifier
        switch actionIdentifier {
        case UNNotificationDismissActionIdentifier: // Notification was dismissed by user

            completionHandler()
        case UNNotificationDefaultActionIdentifier: // App was opened from notification

            completionHandler()
        default:
            completionHandler()
        }
    }

我的代码可以很好地工作并完成所有工作，但徽章编号始终对任何帮助都将有很大帮助。

Answer 1

在云功能（打字稿）中，您将在徽章中发送1，因此只会得到1，将徽章编号更改为2或3，然后它将反映在didReceive方法中。

您应该提出一些逻辑，以使云功能（打字稿）中的徽章编号动态化。

Answer 2

更改此行：

UIApplication.shared.applicationIconBadgeNumber += 1

徽章数量始终为一（云功能）
