【中文标题】Swift firebase 推送通知无法使用零错误?【英文标题】:Swift firebase push notification not working with zero error? 【发布时间】:2020-02-12 11:45:17 【问题描述】:我尝试创建推送通知,我成功生成了 APNs 身份验证密钥,并将其上传到 firebase,一切都在那里工作。我在我的应用程序委托中添加了一些功能和委托:
let notificationCenter = UNUserNotificationCenter.current()//Yeni
notificationCenter.delegate = self//yeni
// [START set_messaging_delegate]
Messaging.messaging().delegate = self as? MessagingDelegate
// [END set_messaging_delegate]
// 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 as? UNUserNotificationCenterDelegate
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()
// [START receive_message]
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any])
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey]
print("Message ID: \(messageID)")
// Print full message.
print(userInfo)
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey]
print("Message ID: \(messageID)")
// Print full message.
print(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
// [END receive_message]
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error)
print("Unable to register for remote notifications: \(error.localizedDescription)")
// This function is added here only for debugging purposes, and can be removed if swizzling is enabled.
// If swizzling is disabled then this function must be implemented so that the APNs token can be paired to
// the FCM registration token.
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
print("APNs token retrieved: \(deviceToken)")
// With swizzling disabled you must set the APNs token here.
// Messaging.messaging().apnsToken = deviceToken
还有这些代码扩展:
// [START ios_10_message_handling]
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate
// Receive displayed notifications for iOS 10 devices.
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
let userInfo = notification.request.content.userInfo
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
completionHandler([.alert, .sound])
if let messageID = userInfo[gcmMessageIDKey]
print("Message ID: \(messageID)")
// Print full message.
print(userInfo)
// Change this to your preferred presentation option
completionHandler([])
extension AppDelegate : MessagingDelegate
// [START refresh_token]
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String)
print("Firebase registration token: \(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.
// [END refresh_token]
// [START ios_10_data_message]
// Receive data messages on iOS 10+ directly from FCM (bypassing APNs) when the app is in the foreground.
// To enable direct data messages, you can set Messaging.messaging().shouldEstablishDirectChannel to true.
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage)
print("Received data message: \(remoteMessage.appData)")
// [END ios_10_data_message]
在那一点上我找不到任何问题。我在 firebase 中创建了新的推送通知,但我无法从我的设备访问它。我已经一次又一次地阅读文档,但在我的代码中找不到任何问题。为什么会这样?我的错在哪里?
【问题讨论】:
【参考方案1】:您是否在您的应用中添加了 PushNotifications 功能?
您的 Firebase 消息传递是否正确配置?
您是否上传了正确的 APNs 证书?
