【问题描述】：
长期以来，我一直在尝试在我的 ios 应用中获取 firebase 推送通知。我已经尝试了互联网上我能找到的一切。但遗憾的是没有运气。
任何帮助，将不胜感激。
我正在通过 firebase 控制台发送通知。有时当应用程序在前台运行时，最后一部分
extension AppDelegate : FIRMessagingDelegate {
// Receive data message on iOS 10 devices.
func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
print("noti recieve remote notification in extesnion")
print("%@ debug", remoteMessage)
print("%@", remoteMessage.appData)
}
被调用，但当应用程序处于后台时没有任何反应。我在功能中启用了“推送通知”和“后台模式”。
我仅在 ios 10 设备上对此进行了测试。
这是我在AppDelegate.swift中的代码
import UIKit
import FirebaseMessaging
import Firebase
import UserNotifications
import FirebaseInstanceID
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FIRApp.configure()
/* let notificationType : UIUserNotificationType = [UIUserNotificationType.alert, UIUserNotificationType.badge, UIUserNotificationType.sound]
let notificationSettings: UIUserNotificationSettings = UIUserNotificationSettings(types:notificationType,categories:nil)
application.registerForRemoteNotifications()
application.registerUserNotificationSettings(notificationSettings)*/
if #available(iOS 10.0, *) {
print("if ios 10 ")
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
application.registerForRemoteNotifications()
} else {
print("noti not ios 10")
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
// [END register_for_notifications]
// Add observer for InstanceID token refresh callback.
NotificationCenter.default.addObserver(self,
selector: #selector(self.tokenRefreshNotification),
name: NSNotification.Name.firInstanceIDTokenRefresh,
object: nil)
return true }
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
print("noti didRegister notification woth device tocken")
/* let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
var tokenString = ""
for i in 0..<deviceToken.count {
tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}*/
/* var token: String = ""
for i in 0..<deviceToken.count {
token += String(format: "%02.2hhx", deviceToken[i] as CVarArg)
}
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.prod)
print("noti tokenString: \(token)")*/
}
func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

【问题讨论】：
-
尝试将消息的优先级设置为
high -
@TonyMkenu 感谢您的帮助，但我已经尝试设置它。这不是问题。
-
@MuneefM 我也有同样的问题。你有解决办法吗？如果是的话，你能帮我解决这个问题吗？
-
@GaneshKumar 我还没有找到解决方案。我暂停了它的工作，希望这可能是苹果或 FCM 中的一个错误。并将在最近的更新中修复。无论如何，如果您找到解决方案，也请在此处发布。谢谢
-
您是否仅将 FCM 用于远程推送通知？如果您仅将 Firebase 用于远程推送通知，请删除
FIRMessagingDelegate并删除connectToFcm方法。你不会需要它。让我知道它是否有效。
