【问题描述】:
适用于所有在更新到 iOS14 和 Xcode12 后因 FCM 而疯狂的人。我花了 2 天时间解决了这些问题。在模拟器上,它可以工作,但在真实设备上,它不会。也许这些说明可以帮助某人并防止浪费时间。另外,如果所有这些步骤都可以改进,那么听听 Flutter Guru 的一些想法会很棒:)。
通知:Instructions for new FCM versions 9+
XCode 设置
AppDelegate.swift
import UIKit
import Flutter
import GoogleMaps
import Firebase
import FirebaseMessaging
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
}
GMSServices.provideAPIKey("")
GeneratedPluginRegistrant.register(with: self)
application.registerForRemoteNotifications()
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Auth.auth().setAPNSToken(deviceToken, type: .prod)
}
override func application(_ application: UIApplication,
didReceiveRemoteNotification notification: [AnyHashable : Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
if Auth.auth().canHandleNotification(notification) {
completionHandler(.noData)
return
}
}
override func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
if Auth.auth().canHandle(url) {
return true
}
return false;
}
}
Info.plist
<key>FirebaseAppDelegateProxyEnabled</key>
<false/>
<key>FirebaseScreenReportingEnabled</key>
<true/>
消息示例(可调用函数)
您的消息必须使用以下选项发送:
{
mutableContent: true,
contentAvailable: true,
apnsPushType: "background"
}
只是在可调用函数中使用的示例
exports.sendNotification = functions.https.onCall(
async (data) => {
console.log(data, "this sendNotification data");
var userTokens = [USERTOKEN1,USERTOKEN2,USERTOKEN3];
var payload = {
notification: {
title: '',
body: '',
image: '',
},
data: {
type:'',
},
};
for (const [userToken,userUID] of Object.entries(userTokens)) {
admin.messaging().sendToDevice(userToken, payload, {
mutableContent: true,
contentAvailable: true,
apnsPushType: "background"
});
}
return {code: 100, message: "notifications send successfully"};
});
Flutter 消息服务
import 'dart:io';
import 'package:hive/hive.dart';
import 'package:firebase_messaging/firebase_messaging.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart';
import 'package:octopoos/providers/app.dart';
Future<dynamic> backgroundMessageHandler(Map<String, dynamic> message) async {}
class FirebaseMessagingService {
final _app = AppProvider();
var _prefs = Hive.box('preferences');
FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
FlutterLocalNotificationsPlugin _flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();
void initialise() {
var android = AndroidInitializationSettings('mipmap/ic_launcher');
var ios = IOSInitializationSettings();
var platform = InitializationSettings(android, ios);
_flutterLocalNotificationsPlugin.initialize(platform);
_firebaseMessaging.configure(
onLaunch: (Map<String, dynamic> message) async {
_app.storeNotification(message);
},
onResume: (Map<String, dynamic> message) async {
_app.storeNotification(message);
},
onMessage: (Map<String, dynamic> message) async {
_app.storeNotification(message);
if (_prefs.get('pushServiceState') == true) _showNotification(message);
},
onBackgroundMessage: Platform.isIOS ? null : backgroundMessageHandler,
);
if (Platform.isIOS) iOSPermission();
_firebaseMessaging.getToken().then((token) {
_prefs.put('fcmToken', token);
});
}
void iOSPermission() {
_firebaseMessaging.requestNotificationPermissions(
IosNotificationSettings(sound: true, badge: true, alert: true, provisional: true));
_firebaseMessaging.onIosSettingsRegistered.listen((IosNotificationSettings settings) {
print('IOS Setting Registed');
});
}
Future<void> _showNotification(Map<String, dynamic> message) async {
var android = AndroidNotificationDetails(
'messages',
"Octopoos",
"channelDescription",
);
var iOS = IOSNotificationDetails();
await _flutterLocalNotificationsPlugin.show(
0,
message['notification']['title'],
message['notification']['body'],
NotificationDetails(android, iOS),
);
}
}
调用小部件
final FirebaseMessagingService _fcm = FirebaseMessagingService();
@override
void afterFirstLayout(BuildContext context) {
_fcm.initialise();
}
只有经过所有这些步骤,我的 FCM 才能正常工作。

或者,您可以轻松地将 OneSignal 集成到您的应用程序中。它很容易集成。只需几个简单的步骤。

我收到此错误。当 ios 应用程序进入后台时。通知未在后台唤醒并终止模式 2020-10-07 15:49:39.938174+0530 Runner[49045:310352] 无法结束 BackgroundTask:不存在标识符为 12 的后台任务(0xc),或者它可能已经结束。中断 UIApplicationEndBackgroundTaskError() 进行调试。
-
无法结束 BackgroundTask:不存在标识符为 35 (0x23) 的后台任务,或者它可能已经结束。中断 UIApplicationEndBackgroundTaskError() 进行调试。
-
AppDelegate 和 info.plist 中没有任何变化,没有任何区别
-
什么是“身份验证”? /Users/development//ios/Runner/AppDelegate.swift:28:10: 错误:在范围内找不到'Auth'
