我几周来一直在尝试让推送通知在 iOS 上正常工作,但没有成功。我已经仔细查看了文档来验证我的配置。不过,推送通知在 Android 上可以正常工作。
我还测试了直接从 firebase 消息控制台向 IOS 发送消息,但仍然不成功。我还尝试了之前的堆栈溢出帖子中的许多建议,但没有成功。

iOS FirebaseCloudMessaging 通知在调试/测试飞行或发布中不起作用
我使用的是运行 iOS 14.6 的实体 iPhone 12。我使用的 Xcode 版本是 12.5。 Xcode配置如下。
应用程序委托文件的代码
import UIKit
import Flutter
import Firebase
import FirebaseMessaging
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
super.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
}
}
如何请求推送通知的代码
Future<void> notficationsPermission () async {
FirebaseMessaging messaging = FirebaseMessaging.instance;
NotificationSettings settings = await messaging.requestPermission(
alert: true,
announcement: true,
badge: true,
carPlay: false,
criticalAlert: true,
provisional: false,
sound: true,
);
print('User granted permission: ${settings.authorizationStatus}');
String uid = Pref.getString(Keys.USER_ID);
var databaseReference = FirebaseDatabase.instance.reference();
if(settings.authorizationStatus == AuthorizationStatus.authorized){
notficationStatus = true;
await FirebaseMessaging.instance.setForegroundNotificationPresentationOptions(
alert: true, // Required to display a heads up notification
badge: true,
sound: true,
);
}
else{
notficationStatus = false;
}
}
}
如何配置通知的片段
return admin.messaging().sendToTopic(
topicName, {
android: {
priority: "high",
},
// Add APNS (Apple) config
apns: {
payload: {
aps: {
contentAvailable: true,
},
},
headers: {
"apns-push-type": "background",
"apns-priority": "5", // Must be `5` when `contentAvailable` is set to true.
"apns-topic": "io.flutter.plugins.firebase.messaging", // bundle identifier
},
},
notification: {
title: snapshot2.val().group_name +
": new chat message",
body: name +":"+snapshot.val().message,
clickAction: "FLUTTER_NOTIFICATION_CLICK",
},
});
我的 Info.plist 中还有以下内容。
<key>FirebaseAppDelegateProxyEnabled</key>
<string>0</string>
我终于弄清楚了,但忘了发布答案! 在我的index.js中
exports.chatNotfi = functions.database.ref("messages/{gId}/{chat}")
.onCreate((snapshot, context)=>{
const groupId = context.params.gId;
console.log("Group id:" + groupId);
const topicName = groupId + "chat";
console.log("topic name"+topicName);
const userId = snapshot.val().userId;
return admin.database().ref("groups/"+groupId+ "/").once("value").
then((snapshot2)=>{
return admin.messaging().sendToTopic(
topicName, {
notification: {
title:
": New chat message",
body: name +":"+snapshot.val().message,
clickAction: "FLUTTER_NOTIFICATION_CLICK",
},
});
});
在我的 AppDelegate.swift 中
import UIKit
import Flutter
import Firebase
import FirebaseMessaging
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions:
[UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
FirebaseApp.configure()
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions:
launchOptions)
}
override func application(_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
super.application(application,
didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
}
}
在我的 Info.plist 中
<key>FirebaseAppDelegateProxyEnabled</key>
<string>NO</string>
<key>UIBackgroundModes</key>
<array>
<string>fetch</string>
<string>remote-notification</string>
</array>
还要确保在 Firebase 控制台中注册的应用程序与 Xcode 中使用的包标识符匹配。
有多种情况会导致您没有收到提醒通知
最近对 SDK 进行更改后,您不必使用 fontawesomenotifications 等软件包手动显示推送通知,如果 SDK 将其识别为背景/通知,则 SDK 会自行处理后台和前台的平视通知类型,但是如果您使用的是早期的 SDK,则必须在前台消息侦听器中手动编写 fontawesomenotifications.show() 如果您在最新的 SDK 中编写此 fontawesomenotifications.show(),您可能会收到两次通知
我正在使用自定义 Django 后端来触发向我的 Flutter 应用程序发送推送通知,这是代码
请记住为 ios 添加 content_available=True 和 sound='default',以便 SDK 会将其视为通知类型并弹出带有声音的平视通知
这对我有用!!
