Firebase - 推送通知 - 不工作

【中文标题】Firebase - 推送通知 - 不工作【英文标题】：Firebase - Push Notifications - Not working 【发布时间】：2018-11-27 09:20:33 【问题描述】：我只是在尝试使用 Firebase 推送通知；作为开始，我遵循了这个文件： https://www.appcoda.com/firebase-push-notifications/
这里是我此时的相关代码： （它构建没有任何问题）
......
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool
......
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: _, _ in )
application.registerForRemoteNotifications()
FirebaseApp.configure()
......
return true
......
// The callback to handle data message received via FCM for devices running ios 10 or above.
func applicationReceivedRemoteMessage(_ remoteMessage: MessagingRemoteMessage)
print(#function)
print(remoteMessage.appData)
当我尝试测试它时（按照前面提到的文档中的建议），函数 applicationReceivedRemoteMessage() 永远不会被调用，我看不到任何事情发生。我错过了什么？有什么我应该先看的吗？
有关信息，我使用的是 Xcode 10.1、iOS 12.1 和 Swift 4.2。
【问题讨论】：
您是否在 Firebase 控制台的项目设置中添加了 .p12 证书？ 是的，我做到了，一切看起来都很好。 你用func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)方法检查了吗？
取得一些进展后，我在另一篇文章中重新提出了修改后的问题：***.com/questions/53512234/…
【参考方案1】：
检查以下代码：
import Firebase
import UserNotifications
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool
setupFireBase(application)
func setupFireBase(_ application: UIApplication)
FirebaseApp.configure()
Messaging.messaging().delegate = self
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()
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String)
print("Firebase registration token: \(fcmToken)")
print(messaging)
ClassUserDefault.shared.deviceToken = fcmToken
let dataDict: [String: String] = ["token": fcmToken]
NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
// TODO: If necessary send token to application server.
// Note: This callback is fired at each app startup and whenever a new token is generated.
connectToFcm()
// [START refresh_token]
func tokenRefreshNotification(_ notification: Notification)
InstanceID.instanceID().instanceID (result, error) in
if let error = error
print("Error fetching remote instange ID: \(error)")
else if let result = result
print("Remote instance ID token: \(result.token)")
connectToFcm()
func connectToFcm()
InstanceID.instanceID().instanceID (result, error) in
if let _ = error
return
else if let result = result
print("Remote instance ID token: \(result.token)")
func application(application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData)
Messaging.messaging().apnsToken = deviceToken as Data
public func application(received remoteMessage: MessagingRemoteMessage)
print(remoteMessage.appData)
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (_ options: UNNotificationPresentationOptions) -> Void)
completionHandler([UNNotificationPresentationOptions.alert, UNNotificationPresentationOptions.sound, UNNotificationPresentationOptions.badge])
print("Handle push from background or closed")
print("\(notification.request.content.userInfo)")
let _ResponsePush = ClassResponsePush(fromData: notification.request.content.userInfo)
//AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
if notification.request.content.userInfo.isEmpty
return
else
print(_ResponsePush)
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
print("Handle push from background or closed")
print("\(response.notification.request.content.userInfo)")
let _ResponsePush = ClassResponsePush(fromData: response.notification.request.content.userInfo)
if response.notification.request.content.userInfo.isEmpty return else
handlePush(userInfo: _ResponsePush)
print(_ResponsePush)
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
let chars = (deviceToken as NSData).bytes.bindMemory(to: CChar.self, capacity: deviceToken.count)
var token = ""
for i in 0..<deviceToken.count
token += String(format: "%02.2hhx", arguments: [chars[i]])
print("Device Token = ", token)
func applicationReceivedRemoteMessage(_ remoteMessage: MessagingRemoteMessage)
print("Received data message: \(remoteMessage.appData)")
func handlePush(userInfo: ClassResponsePush)
不要忘记在 Firebase 控制台的项目设置的云消息传递中添加 .p12 文件。
希望对你有帮助:)
【讨论】：
我看了你的代码，我有两个问题：ClassUserDefault 和 ClassResponsePush 来自哪里？ 两者都是单例类，一类是用户默认保存令牌，而类responsepush是即将到来的响应的响应处理程序，与可编码的相同。明天我会为你提供这两个课程的代码。 取得一些进展后，我在另一篇文章中重新提出了修改后的问题：***.com/questions/53512234/…【参考方案2】：你好，米歇尔，
根据您的参考链接，您似乎错过了这一行
FIRMessaging.messaging().remoteMessageDelegate = self
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 )
// 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()
FIRApp.configure()
【讨论】：
确实我已经注释掉了这一行，因为它会产生一个错误：“'Messaging' 类型的值没有成员'remoteMessageDelegate'” @Michel 请检查您关注的链接appcoda.com/firebase-push-notifications @Michel 你也可以在这里查看....***.com/questions/51685040/…以上是关于Firebase - 推送通知 - 不工作的主要内容，如果未能解决你的问题，请参考以下文章
