iOS 推送通知在 flutter 中不起作用

Question

我的应用程序需要推送通知。我只是遵循flutterfire 指南，android 工作正常，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print("PUSH RECEIVED");在FirebaseMessaging.onMessage.listen()或内部执行FirebaseMessaging.onBackgroundMessage()。

另一方面，我配置了整个 Firebase：

\n

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

iOS 设备收不到推送通知的原因有什么想法吗？我想我会提供所有必要的信息，如果您需要什么，请告诉我！提前致谢！

Answer 1

我在 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 中却无法正常工作。

我所做的是按照 firebase 提供的说明集成推送通知（不是 flutter 指南，而是 ios 指南）请按照此链接https://firebase.google.com/docs/cloud-messaging/ios/client

在 ios 中，用户必须授予向他们发送推送通知的权限，这与 Android 不同，因此您要做的是将以下代码添加到 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()

希望这有效
