徽章的数量始终为一个(云功能)

Question

如果节点在Firebase中成功更改，我已从云功能发送通知，但徽章编号始终显示(1(即使我发送多个通知。

我在云中的代码功能(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 (swift( 中的代码：

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()
}
}

我的代码工作正常并且可以完成所有工作，但徽章编号它保留在一个任何帮助中，非常感谢。

Answer 1

在您的云函数(打字稿(中，您正在发送 1 in 徽章，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。

您应该放置一些逻辑以使徽章编号在云功能(打字稿(中动态化。

Answer 2

更改此行：

UIApplication.shared.applicationIconBadgeNumber += 1
