Question

您好，您好，新手在这里！我使用的是本地通知，并向我的应用添加了默认代码。它可以在Android中使用，但不能在iOS中使用。知道为什么吗？

我同时尝试了适用于iPhone 8和iPhone 11的iOS模拟器。它可以在我的Android模拟器（Pixel 3 API 29）上运行。

我还为此应用启用了iOS中的通知（设置>此应用>通知），并授予了权限。

对于Android，我已经在AndroidManifest.xml中添加了权限请求。

import 'package:flutter/material.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart';


class AppNotification extends StatefulWidget {
  static const String id = 'app_notification';

  @override
  _AppNotificationState createState() => _AppNotificationState();
}

class _AppNotificationState extends State<AppNotification> {
  FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin;

  @override
  void initState() {
    super.initState();
    flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();
    var android = AndroidInitializationSettings('app_icon');
    var iOS = IOSInitializationSettings();
    var initSettings = InitializationSettings(android, iOS);

    flutterLocalNotificationsPlugin.initialize(initSettings,
        onSelectNotification: onSelectNotification);
  }

  Future onSelectNotification(String payload) async {
    debugPrint("payload : $payload");
    showDialog(
      context: context,
      builder: (_) {
        return AlertDialog(
          title: Text("PayLoad"),
          content: Text("Payload : $payload"),
        );
      },
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            FlatButton(
              child: Text('Notification'),
              onPressed: _showNotificationWithDefaultSound,
            ),
            FlatButton(
              onPressed: () {
                Navigator.pop(context);
              },
              child: Text('back'),
            )
          ],
        ),
      ),
    );
  }

  // TODO iOS doesn't work

  Future _showNotificationWithDefaultSound() async {
    var androidPlatformChannelSpecifics = new AndroidNotificationDetails(
        'your channel id', 'your channel name', 'your channel description',
        importance: Importance.Max, priority: Priority.High);
    var iOSPlatformChannelSpecifics = new IOSNotificationDetails();
    var platformChannelSpecifics = new NotificationDetails(
        androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
    await flutterLocalNotificationsPlugin.show(
      0,
      'New Post',
      'How to Show Notification in Flutter',
      platformChannelSpecifics,
      payload: 'Default_Sound',
    );
  }

我在didFinishLaunchingWithOptions方法内的“ AppDelegate.swift”中添加了这一行，它解决了我的问题：

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

// 我希望在插件的文档中找到它它可以解决您的问题！

Flutter本地通知不适用于iOS
