【中文标题】iOS FCM 没有收到推送通知【英文标题】：iOS FCM not getting push notifications 【发布时间】：2016-12-22 08:31:14 【问题描述】：自从我更新到 swift 3，FCM 不起作用。
Push Notifications 在 Capabilities 中启用，证书在 Firebase 控制台上更新。
顺便说一句，android 应用程序上的 fcm 工作正常，它在 ios 上工作，但在更新 swift 3 和新的 firebase 库后，它没有。
AppDelegate.swift：
class AppDelegate: UIResponder, UIApplicationDelegate
var window: UIWindow?
let notificationCenter = NotificationCenter.default
var connectedToFcm: Bool = false
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool
let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
FIRApp.configure()
NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotification), name: NSNotification.Name.firInstanceIDTokenRefresh, object: nil)
return true
func applicationDidEnterBackground(_ application: UIApplication)
disconnectFromFcm()
func applicationDidBecomeActive(_ application: UIApplication)
connectToFcm()
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
print("REGISTRED")
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: .unknown)
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError
error: Error )
print("Registration for remote notification failed with error: \(error.localizedDescription)")
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any])
print(userInfo)
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)
print(userInfo)
func tokenRefreshNotification(_ notification: Notification)
let refreshedToken = FIRInstanceID.instanceID().token()
if refreshedToken != nil
print("InstanceID token: \(refreshedToken!)")
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
func connectToFcm()
guard FIRInstanceID.instanceID().token() != nil else
return;
if connectedToFcm == false
FIRMessaging.messaging().disconnect()
FIRMessaging.messaging().connect (error) in
if (error != nil)
self.connectedToFcm = false
print("Unable to connect with FCM. \(error)")
else
self.connectedToFcm = true
print("Connected to FCM.")
self.sendTokenToServer()
return
func sendTokenToServer()
let fcmToken = FIRInstanceID.instanceID().token()
if self.sharedUser.getToken().characters.count == 0 || fcmToken == nil
return
let params = [
"reg_id": fcmToken!,
"dev_id": Config().devId
]
Alamofire.request(Config().fcmUrl, method: .post, parameters: params, encoding: JSONEncoding.default, headers: Config().apiHeaders)
.validate()
.responseJSON response in
if response.result.isSuccess
print("FCM token send to app server")
func disconnectFromFcm()
FIRMessaging.messaging().disconnect()
connectedToFcm = false
print("Disconnected to FCM")

Connected to FCM.
FCM token send to app server
我进行了打印以检查应用程序是否获得令牌，并且确实如此。此外，令牌被发送到服务器，我在那里检查它是否正常以及服务器是否正在发送推送。
【问题讨论】：
您是如何发送推送通知的？是数据消息还是通知消息？ 我发送json数据。如果你是这个意思？ 【参考方案1】：我在 iOS FCM 集成中遇到了同样的问题，我已经通过在 iOS 10 中使用最新的推送通知代码解决了这个问题。
您需要检查设备的操作系统版本并隔离相关代码。
if #available(iOS 10, *)
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.sound, .alert, .badge]) (granted, error) in
if error == nil
UIApplication.shared.registerForRemoteNotifications()
else
// Register for remote notifications
if #available(iOS 8.0, *)
// [START register_for_notifications]
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
// [END register_for_notifications]
else
// Fallback
let types: UIRemoteNotificationType = [.alert, .badge, .sound]
application.registerForRemoteNotifications(matching: types)
将此代码放在一个函数中并从完成启动时调用它并注释您的代码。 如果您还有任何问题，请告诉我。
重要：- 导入用户通知
委托：-
func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings)
/**
Allow device to register for remote notification.
*/
UIApplication.shared.registerForRemoteNotifications()
FIRMessaging.messaging().subscribe(toTopic: "/topics/test")
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
/**
Send device token to firebase to get the FCM token for pushnotification from firebase.
*/
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.prod)
【讨论】：
我放了没有功能的代码，需要UNUserNotificationCenterDelegate，但结果还是一样，没有成功。
我已经编辑了我的答案，请检查并告诉我。同样对于这一行 FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: .unknown) 我正在使用 -> FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: .sandbox) 进行发布构建的开发和生产。请查看编辑后的答案，让我知道它是否有效。
我试过.sandbox和.prod还是一样:(
即使我也面临同样的问题。为什么你调用这个 FIRMessaging.messaging().subscribe(toTopic: "/topics/test")
@MirzaDelic - 你从控制台测试过吗？以上是关于iOS FCM 没有收到推送通知的主要内容，如果未能解决你的问题，请参考以下文章
