没有收到来自 Firebase 控制台的推送通知

Question

我已经实现了有关实现推送通知的所有步骤，但是当我测试通知控制台时，它没有进入iPhone，但是当我使用生产APNS证书n与"https://pushtry.com/"中的密码n令牌进行测试时，它工作正常。 我无法纠正为什么这是Heppening.我还启用了来自功能部分的推送通知。谢谢 下面是我的应用程序委托代码

mport Firebase

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
// show the notification alert (banner), and with sound
completionHandler([.alert, .sound])
}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
// tell the app that we have finished processing the user’s action / response
let application = UIApplication.shared

completionHandler()

func applicationWillResignActive(_ application: UIApplication) {

func applicationDidEnterBackground(_ application: UIApplication) {

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 applicationWillTerminate(_ application: UIApplication) {

Answer 1

需要执行几个步骤来测试推送通知：

• 确保使用真实设备进行测试
• 您可以在函数 didRegisterForRemoteNotificationsWithDeviceToken 中获取远程实例 ID，如下所示，然后使用 Firebase 控制台将推送通知直接发送到设备令牌：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
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)")
}
}
}

• 如果不起作用，请检查您是否在 Firebase 控制台设置中上传了正确的 APNs 身份验证密钥或 APNs 证书。

**首先，您应该检查所有证书类型是否正确** 之后在应用程序中

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// 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()        
// END register for notifications
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
InstanceID.instanceID().instanceID { (result, error) in
if let error = error {
print("Error fetching remote instance ID: (error)")
} else if let result = result {
print("Result (result)")
}
}
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.hexString
}

同时将您的 p.12 文件上传到 Firebase 控制台
