Question

我正在使用flutter应用程序设置fcm，并使用本地通知在应用程序处于前台状态时显示通知。

在android中完美运行，没有任何错误。但是在IOS上，本地通知不起作用。它没有显示错误或其他任何内容，但是当应用程序在前台运行时，它现在完全显示了通知横幅

这是本地通知的设置：

var android = AndroidInitializationSettings('mipmap/ic_launcher');
var ios = IOSInitializationSettings();
var platform = new InitializationSettings(android, ios);
flutterLocalNotificationsPlugin.initialize(platform);
_firebaseMessaging.requestNotificationPermissions(
 const IosNotificationSettings(sound: true, badge: true, alert: true, provisional: false));

然后是showNotification函数，它是这样的：

 showNotification(Map<String, dynamic> message) async {
var android = new AndroidNotificationDetails(
    'IMPORTANT1', 'SHOW BANNER', 'ALWAYS SHOWS BANNER',
    importance: Importance.Max, priority: Priority.High, ticker: 'ticker');
var ios = new IOSNotificationDetails();
var platform = NotificationDetails(android, ios);
await flutterLocalNotificationsPlugin.show(
    0,
    message['notification']['title'],
    message['notification']['body'],
    platform); }

我已经通过互联网进行搜索，发现我需要使用

if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}

，我将其添加到AppDelegate.swift，但仍无法正常工作

谢谢

已通过将flutter本地通知插件更新为最新版本并从设备中删除该应用程序并运行flutter clean来解决了

Answer 2

请在 appDelegate 文件中试试这个

import UIKit
import Flutter
import UserNotifications

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate, UNUserNotificationCenterDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    // set the delegate in didFinishLaunchingWithOptions
    UNUserNotificationCenter.current().delegate = self
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
    // This method will be called when app received push notifications in foreground
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
    {
        completionHandler([.alert, .badge, .sound])
    }
}

颤抖的本地通知不适用于IOS
