未调用 iOS 回调的 FCM 推送

Question

我对 FCM 推送通知有疑问。

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Swift.Void)

和

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Swift.Void) 

当我收到推送时不会调用。通知是在我的 iPhone 中生成的。

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)

被调用，但我不明白为什么，因为它已被弃用。

我的通知内容：

{
  "to": "FCM Token",
  "priority": "high",
  "content_available": true,
  "notification": {
    "sound": "default",
    "title": "Test",
    "body": "Test",
    "description": "Test"
  },
  "data": {
    "id": 123456,
    "status": "11",
  }
}

在我的 AppDelegate.swift 中：

import UIKit
import CoreData
import Firebase

        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(

            completionHandler: {_, _ in })

     }
 }

在我的 Info.plist 中，我将 FirebaseAppdelegateProxyEnable 设置为 NO

在功能方面，我启用了推送通知，并且在后台模式下也启用了远程通知。

我使用的是 Xcode 11.1。我已将我的项目转换为 Swift 5（它是使用 Swift 3 创建的），我已将构建系统更改为新的。

我在这个项目中有两个目标，我不知道它是否与我的问题有关。

我尝试使用具有相同 AppDelegate.swift、相同包标识符的空新项目并且它可以工作。

试试这个

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    // put your code here
}

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    // put your code here
}
