我已经按照Firebase控制台中提供的说明创建了一个示例ios应用程序，用于在ios设备上接收云消息。通知消息从控制台发送，并打印在应用程序控制台上。但是，即使在授予必要的权限后，也不会在设备上收到推送通知。
我使用的是 swift 3 和 xCode 版本 10.3。在 Firebase 控制台中注册了应用，并通过应用接收并添加所需的 FCM 令牌以向设备发送测试消息。尝试通过控制台发送大量消息，但没有一条显示在设备上。它显示在控制台上成功发送消息时。
以下是我为接收推送通知而编写的 AppDelegate.swift 文件。
import UIKit
import UserNotifications
import Firebase
import FirebaseMessaging
import FirebaseInstanceID
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let gcmMessageIDKey = "gcm.message_id"
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
if #available(iOS 10.0, *) {
FirebaseApp.configure()
Messaging.messaging().delegate = self
Messaging.messaging().shouldEstablishDirectChannel = true
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)
}
// request permission from user to send notification
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound], completionHandler: { authorized, error in
if authorized {
DispatchQueue.main.async(execute: {
application.registerForRemoteNotifications()
})
}
else{
print("Notification access denied")
}
})
return true
}
// [START receive_message]
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: (messageID)")
}
print(userInfo)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: (messageID)")
}
print(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("Unable to register for remote notifications: (error.localizedDescription)")
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
print("APNs token retrieved: (deviceToken)")
}
}
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
print(userInfo)
print("Message ID: (userInfo["gcm.message_id"]!)")
completionHandler(UNNotificationPresentationOptions.alert)
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
print("Do what ever you want")
// Print full message.
print("tap on on forground app",userInfo)
completionHandler()
}
}
extension AppDelegate : MessagingDelegate {
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: (fcmToken)")
Messaging.messaging().subscribe(toTopic: "/topics/nutriewell_live")
Messaging.messaging().shouldEstablishDirectChannel = true
}
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print("Received data message: (remoteMessage.appData)")
}
}
我期望在ios设备上收到推送通知，但我没有收到任何通知。 我收到以下输出，该输出与从控制台发送的通知消息一起打印。

我能在这里得到任何帮助吗？
有两种方法可以接收通知：
-
当应用程序关闭/处于非活动状态并且您在 didFinishLaunchingWithOptions 中获得有效负载时：
-
当应用程序处于打开/活动状态并且当前可见时，您会在 didReceiveRemoteNotification 中获得有效负载：
当您的应用程序关闭时，iOS 会负责显示通知(如果未开发通知扩展(，并在您点击它时启动您的应用程序。
如果您的应用程序已打开，则必须注意显示此通知或忽略它。
以下是官方文件所说的：
当本地和远程通知不由您的 应用程序或用户，它们将显示在通知中心中，以便 以后可以查看它们。使用getDeliveredNotificationsWithCompletionHandler：共享的UNUserNotificationCenter对象的方法，用于获取 通知仍显示在"通知中心"中。如果你 查找任何现已过时且不应过期的通知 显示给用户，您可以使用removeDeliveredNotificationsWithIdentifiers：方法。
