我正在使用this tutorial和this project作为参考。这是我在AppDelegate中的代码
import UIKit
import UserNotifications
import Firebase
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let gcmMessageIDKey = "gcm.message_id"
let preferences = UserDefaults.standard
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
Messaging.messaging().delegate = self
if #available(iOS 10.0, *) {
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()
FirebaseApp.configure()
return true
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
print("message1:",userInfo)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
print("message2:", 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) {
print("APNs token retrieved: \(deviceToken)")
let apn = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
Messaging.messaging().appDidReceiveMessage(userInfo)
}
}
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
print("userinfo", userInfo)
completionHandler([])
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
print("userinfo", userInfo)
completionHandler()
}
}
extension AppDelegate : MessagingDelegate {
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
print("Firebase registration token: \(fcmToken)")
}
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print("Received data message: \(remoteMessage.appData)")
}
}
我有fcmtoken和APNs token 。我已经上传了我的开发APNs证书。我已将“功能上的推送通知”设置为“开”。我已经在设备上尝试过了。我在项目中添加了GoogleService-Info.plist。但是我没有从前台或后台收到任何通知。
我在代码上犯了任何错误吗？还是我需要更新证书？顺便说一下，我对此很陌生。
有人可以帮我解决吗？我真的很感激。
谢谢!
最佳答案
您必须在数据库中注册deviceTokenString或deviceTokenId，并且必须根据需要获得正确的分发或开发证书，这是接收推送通知的基本要求。
从您的代码中，您没有注册deviceTokenString/Id。
谢谢
