【中文标题】Xcode 8.3 Swift 3 FCM 通知上的 Firebase 问题 iOS 10.3 不起作用【英文标题】：Firebase Issues iOS 10.3 on Xcode 8.3 Swift 3 FCM notifications not working 【发布时间】：2017-05-30 15:28:59 【问题描述】：我正在使用 Swift 3 为 iOS 10.3.2 开发 Xcode 8.3.2，我的项目使用 firebase 云消息传递，当我的 p12 证书已过期，我按照 Firebase 文档的建议将我的证书 p12 更新为 p8，但是昨天当我使用控制台 firebase 进行测试，它正在工作，但今天没有，日志正常打印我：

我犯了一些错误？，或者我需要配置一些东西？，更多的东西应该增加 iOS 9 和 iOS 10.3 之间的差异，或者添加到firebase 设置，非常感谢您的帮助

编辑：
再次嗨，我已将 Firebase 更新到最新版本 4.0.0，在我的代码中进行这些更新：
func initializeFCM(_ application: UIApplication)
print("initializeFCM")
//-------------------------------------------------------------------------//
if #available(iOS 10.0, *) // enable new way for notifications on iOS 10
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.badge, .alert , .sound]) (accepted, error) in
if !accepted
print("Notification access denied.")
else
print("Notification access accepted.")
UIApplication.shared.registerForRemoteNotifications();
else
let type: UIUserNotificationType = [UIUserNotificationType.badge, UIUserNotificationType.alert, UIUserNotificationType.sound];
let setting = UIUserNotificationSettings(types: type, categories: nil);
UIApplication.shared.registerUserNotificationSettings(setting);
UIApplication.shared.registerForRemoteNotifications();
//-------------------------------------------------------------------------//

Messaging.messaging().shouldEstablishDirectChannel = true
NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotificaiton),

func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage)
debugPrint("--->messaging:\(messaging)")
debugPrint("--->didReceive Remote Message:\(remoteMessage.appData)")
guard let data =
try? JSONSerialization.data(withJSONObject: remoteMessage.appData, options: .prettyPrinted),
let prettyPrinted = String(data: data, encoding: .utf8) else return
print("Received direct channel message:\n\(prettyPrinted)")
几个警告日志消失了，但是当我以前台和后台方式进行测试时，此日志会打印我：

我试过了，但它仍然显示那些日志并且它没有显示任何通知：
我有什么遗漏吗？谢谢您的回答！
【问题讨论】：
这里有些问题： @ikanimo 我已经更新了我的问题，有什么想法或帮助吗？，再次感谢 您是如何将 .p12 转换为 .p8 的？ 您无法将 .p12 证书转换为 .p8 证书，您必须从头开始创建一个新证书，***.com/questions/39672297/… 【参考方案1】：您需要将推送通知证书添加到 Cloud Messaging 中的 FCM 控制台。只有这样它才能向您的应用程序发送通知。此外，请确保您已在 iOS 应用的功能中启用推送通知。
更新：
extension AppDelegate: MessagingDelegate
// Registering for Firebase notifications
func configureFirebase(application: UIApplication)
FirebaseApp.configure()
Messaging.messaging().delegate = self
// Register for remote notifications. This shows a permission dialog on first run, to
// show the dialog at a more appropriate time move this registration accordingly.
// [START register_for_notifications]
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()
print("-----firebase token: \(String(describing: Messaging.messaging().fcmToken)) ----")
//MARK: FCM Token Refreshed
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String)
// FCM token updated, update it on Backend Server
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage)
print("remoteMessage: \(remoteMessage)")
//Called when a notification is delivered to a foreground app.
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
completionHandler([.alert, .badge, .sound])
//Called to let your app know which action was selected by the user for a given notification.
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
print("User Info = \(response.notification.request.content.userInfo)")
completionHandler()
在您的AppDelegate 的didFinishLaunchingWithOptions 内致电configureFirebase(application:)。
【讨论】：
我做了所有这些，但错误仍然存在，谢谢FIRMessaging.messaging().remoteMessageDelegate = self 尝试在initializeFCM() 之后的center.delegate = self 行之后添加上面的行。另外，请确保您的 AppDelegate 确认 FIRMessagingDelegate 协议。
我已经更新了我的问题，有什么想法或帮助吗？，再次感谢！
@user_Dennis_Mostajo 您需要遵守 MessagingDelegate 协议-func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) // to conform to MessagingDelegate 。在你的 AppDelegate 中添加这个函数
我添加了，如果你修改编辑，我在代码的最后部分实现了那个功能，包括一个调试打印，但仍然打印那个警告日志，我不知道为什么不能识别委托属性以上是关于Xcode 8.3 Swift 3 FCM 通知上的 Firebase 问题 iOS 10.3 不起作用的主要内容，如果未能解决你的问题，请参考以下文章
