iOS推送通知无法正常工作

Question

我的应用需要推送通知。我只关注flutterfire guide，android 正常工作，但不适用于 iOS 应用程序...我认为错误出在通知配置中，因为代码永远不会在 FirebaseMessaging.onMessage.listen() 或 FirebaseMessaging.onBackgroundMessage() 内执行 print("PUSH RECEIVED");。

        badge: true,

      );
    }

另一方面，我配置了整个 Firebase：

• 创建了新的 iOS 应用
• 添加了团队 ID 和应用商店 ID
• 添加了带有密钥 ID 和团队 ID 的 APNS 身份验证密钥

您知道 iOS 设备没有收到推送通知的原因吗？如果你需要什么，我想我会提供所有必要的信息，告诉我！提前致谢！

Answer 1

ios 中的 firebase 推送通知也有同样的问题。我的 android 推送通知工作正常，但在 ios 中没有。

我所做的是按照 firebase 提供的指令集成推送通知（不是颤振指南，而是 ios 指南） 关注此链接https://firebase.google.com/docs/cloud-messaging/ios/client

在 ios 中，用户必须授予权限才能为他们发送推送通知，这与 android 不同 所以你要做的就是将下面的代码添加到 AppDelegate.swift

if #available(iOS 10.0, *) {
  // For iOS 10 display notification (sent via APNS)
  UNUserNotificationCenter.current().delegate = self
  let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
  UNUserNotificationCenter.current().requestAuthorization(
    options: authOptions,
    completionHandler: { _, _ in }
  )
} else {
  let settings: UIUserNotificationSettings =
    UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
  application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()

希望这可行
