[英]Function didReceive remoteMessage not being called Swift 5
所以我一直在這里和其他地方閱讀關於這個主題的其他帖子,但我仍然在掙扎。 我的應用程序正在使用"Fireabase FCM"
進行設備到設備通知。 我能夠發送和接收消息。 但是,從未調用過"didReceive remoteMessage"
方法。 我想使用這個 func 來更新應用程序和標簽欄項目徽章編號。
我嘗試添加其他方法來指示收到消息,但這些方法也沒有奏效。 我想我錯過了一些基本的東西。 我將Swift 5
與Xcode 10
。
import Foundation
import UIKit
import Firebase
import FirebaseFirestore
import FirebaseMessaging
import UserNotifications
class PushNotificationManager : NSObject, MessagingDelegate, UNUserNotificationCenterDelegate {
static let shared = PushNotificationManager( )
var userID: String = ""
var instanceIDToken : String = ""
let defaults = UserDefaults.standard
override init( ) {
super.init()
}
func setUserId(identifier: String) {
userID = identifier
}
func registerForPushNotifications() {
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)
Messaging.messaging().delegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
UIApplication.shared.registerUserNotificationSettings(settings)
}
UIApplication.shared.registerForRemoteNotifications()
UNMutableNotificationContent().sound = UNNotificationSound.default
Messaging.messaging().shouldEstablishDirectChannel = true
updateFirestorePushTokenIfNeeded()
}
func getNotificationSettings( ) {
UNUserNotificationCenter.current().getNotificationSettings { (settings) in
print("Notification settings: \(settings)")
guard settings.authorizationStatus == .authorized else {return}
DispatchQueue.main.async{UIApplication.shared.registerForRemoteNotifications()}
}
}
func updateFirestorePushTokenIfNeeded( ) {
// let mytoken = Messaging.messaging().fcmToken
if let token = Messaging.messaging().fcmToken {
let usersRef = Firestore.firestore().collection("users_table").document(userID)
usersRef.setData(["fcmToken": token], merge: true)
}
}
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print(remoteMessage.appData)
}
func application(received remoteMessage: MessagingRemoteMessage) {
print("applicationReceivedRemoteMessage")
print(remoteMessage.appData)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
print("REMOTE NOTIFICATION RECEIVED")
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: \(fcmToken)")
updateFirestorePushTokenIfNeeded()
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print(response)
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound])
}
func getTokenDirectly( ) {
InstanceID.instanceID().instanceID { (result, error) in
if let error = error {
print("Error fetching remote instance ID: \(error)")
} else if let result = result {
print("Remoted instance ID token: \(result.token)")
self.instanceIDToken = result.token
self.updateFirestorePushTokenIfNeeded()
}
}
}
}
再次,我在我用來測試的設備上收到通知,但
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print(remoteMessage.appData)
}
永遠不會被調用。
您似乎沒有調用此方法:
registerForPushNotifications()
由於那是您將delegate
設置為self
的地方,因此不會調用委托的方法
