我正在为Android和iOS开发一个Flutter应用程序。它具有通知功能，因此我实现了firebase_messaging API。我通过设备ID向特定设备发送通知，并向
我正在测试
以下是我的通知注册代码。
我的登录能力如下：
我是iOS的新手，无法理解发生了什么。我认为就像在Android中一样，当应用程序在后台或关闭时，通知会自动出现在通知栏中。

如@nandish的建议，我已将
topics发送通知。我正在测试
topics的通知发送，在Android中工作得非常好。我按照上面提供的链接中的指南进行操作，也实现了iOS设置。但是在iOS中，当通知被发送时，仅当应用程序在前台时才收到通知。这意味着只能通过onMessage接收。如果应用程序在后台或关闭状态下，我看不到任何通知（我在控制台中打印）。但是当我重新打开应用程序时，通知会被打印出来。以下是我的通知注册代码。
FirebaseMessagesImpl msg = FirebaseMessagesImpl();
msg.requestPermissions();
//Get configured with firebase messaging to recieve messages
msg.getMessage().then((_) {
msg.register().then((String token) {
print(token);
//Register to the `topic` so we get messages sent to the topic
msg.topicRegister();
.........
}
FirebaseMessagesImpl
import 'package:firebase_messaging/firebase_messaging.dart';
import 'package:http/http.dart' as http;
import 'dart:convert' as convert;
class FirebaseMessagesImpl {
final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
String serverToken =
"AAAAAAA:XXXXXXXXX-YYYYYYYY-ZZZZ-BBBBBBBB";
Future<String> register() async {
String token = "";
_firebaseMessaging.getToken().then((t) {
token = t;
print("ha: " + t);
});
return token;
}
Future<void> getMessage() async {
_firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
print('on message $message');
//setState(() => _message = message["notification"]["title"]);
}, onResume: (Map<String, dynamic> message) async {
print('on resume $message');
// setState(() => _message = message["notification"]["title"]);
}, onLaunch: (Map<String, dynamic> message) async {
print('on launch $message');
//setState(() => _message = message["notification"]["title"]);
});
}
void topicRegister() {
// _firebaseMessaging.subscribeToTopic("mobile_admin");
_firebaseMessaging.subscribeToTopic("puppies");
}
void requestPermissions() async
{
await _firebaseMessaging.requestNotificationPermissions(
const IosNotificationSettings(sound:true, badge:true, alert:true, provisional:false)
);
}
}

以下是AppDelegate.swift
import UIKit
import Flutter
import Firebase
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
FirebaseApp.configure()
GeneratedPluginRegistrant.register(with: self)
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
super.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
}
}
正如其他SO答案中的一些人建议的那样，我从AppDelegate.swift代码中删除了以下部分并尝试过，但问题仍然存在。
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}
我已经按照指南将苹果密钥文件上传到Firebase项目的云消息部分。
以下是我的JSON代码发送通知：
{
"notification": {
"body": "body",
"title": "title"
},
"priority": "high",
"data": {
"body": "body",
"title": "title",
"click_action": "FLUTTER_NOTIFICATION_CLICK",
"id": "1",
"status": "done",
"image": "https://ibin.co/2t1lLdpfS06F.png"
},
"to": "/topics/puppies"
}
我的登录能力如下：

更新
如@nandish的建议，我已将AppDelegate.swift文件更改如下：import UIKit
import Flutter
import Firebase
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate, UNUserNotificationCenterDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
FirebaseApp.configure()
GeneratedPluginRegistrant.register(with: self)
UNUserNotificationCenter.current().delegate = self
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
super.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
}
// MARK: - UNUserNotificationCenterDelegate Method
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
}
}
然后我遇到了以下错误
UNUserNotificationCenter' is only available in iOS 10.0 or newer
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
更新
当应用程序发出通知时，在前台，我从应用程序中获得以下响应。这仅在iPhone模拟器中发生，而不是在真实设备上。
{from: /topics/puppies, status: done, id: 1, notification: {body: body, title: title, e: 1, tag: topic_key_9204266xxxxxxx535}, title: title, image: https://ibin.co/2t1lLdpfS06F.png, collapse_key: com.aaa.xxx, body: body, click_action: FLUTTER_NOTIFICATION_CLICK}
