我遇到类似的问题： iOS not receiving notifications from Firebase Cloud Messaging
在我的Firebase console我从我的KeyChain添加了我的Apple iOS开发推送服务.p12键，我添加了GoogleService-Info.plist，标识符也没问题。
此外，在我的Capabilities Push Notifications，Background Modes＆gt; Background fetch和Remote notifications以及Keychain Sharing处于有效状态。
我的 AppDelegate.swift 看起来：
import UIKit
import GoogleMaps
//import FacebookCore
import FBSDKCoreKit
import UserNotifications
import Firebase
import FirebaseCore
import FirebaseInstanceID
import FirebaseMessaging
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let gcmMessageIDKey = "gcm.message_id"
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
GMSServices.provideAPIKey("xxxx-xxx")
if #available(iOS 10.0, *) {
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
// For iOS 10 data message (sent via FCM)
FIRMessaging.messaging().remoteMessageDelegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
// [END register_for_notifications]

当我从Firebase控制台发送消息时，我收到如下消息：
Message ID: 0:1xxxx5994%84df84xxxxx
[AnyHashable("google.c.a.e"): 1, AnyHashable("google.c.a.ts"): 14871xxx, AnyHashable("google.c.a.udt"): 0, AnyHashable("gcm.n.e"): 1, AnyHashable("aps"): {
alert = "This is a test";
}, AnyHashable("google.c.a.c_id"): 5884120750xxxxxx, AnyHashable("gcm.message_id"): 0:1xxxx5994%84df84xxxxx]
但由于某种原因推送通知从未出现在我的设备上。
我做错了什么？
