为什么 FCM 在 Flutter 中无法在 ios 上工作

Question

我正在按照这些步骤使用 firebase 消息向我的应用添加推送通知，但在所有这些步骤之后它不起作用

ios_client

APNs

<key>FirebaseAppDelegateProxyEnabled</key>
<false/>

final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();
  void firebaseTrigger(BuildContext ctx) async {
    _firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print("onLaunch: $message");
        Fluttertoast.showToast(
          msg: message['notification']['title'],
          toastLength: Toast.LENGTH_LONG,
          gravity: ToastGravity.TOP,
          timeInSecForIosWeb: 6,
        );
      },
      onLaunch: (Map<String, dynamic> message) async {
        Navigator.push(
          context,
          MaterialPageRoute(
            builder: (context) => NotificationScreen(),
          ),
        );
      },
      onResume: (Map<String, dynamic> message) async {
        Navigator.push(
          context,
          MaterialPageRoute(
            builder: (context) => NotificationScreen(),
          ),
        );
      },
    );
  }

  @override
  void initState() {
    super.initState();
    firebaseTrigger(context);
    _firebaseMessaging.requestNotificationPermissions(
        const IosNotificationSettings(
            sound: true, badge: true, alert: true, provisional: true));
    _firebaseMessaging.onIosSettingsRegistered
        .listen((IosNotificationSettings settings) {
      print("Settings registered: $settings");
    });
  }

但推送通知仅适用于 ios，但适用于 android 任何人都可以帮助我解决我的问题

编辑：我的 appDelegate

Answer 1

override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let firebaseAuth = Auth.auth()
        firebaseAuth.setAPNSToken(deviceToken, type: AuthAPNSTokenType.unknown)

    }

将此添加到您的 appDelegate.... 这是 appDelegate 的示例

import UIKit
import Flutter

import Firebase
import FirebaseAuth
import UserNotifications
import FirebaseMessaging


@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    

    application.registerForRemoteNotifications()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
  
   override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let firebaseAuth = Auth.auth()
        firebaseAuth.setAPNSToken(deviceToken, type: AuthAPNSTokenType.unknown)

    }
    override func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        let firebaseAuth = Auth.auth()
        if (firebaseAuth.canHandleNotification(userInfo)){
            print(userInfo)
            return
        }
    
    }
   
  
 
}
