I'm trying to listen user clear push notification action. I've the code below, It's working when the app is on the foreground but when i put the app on the background it doesn't go into that function. Is there any way that i can do some coding when the user clear the notification on the background state?
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
if(response.actionIdentifier == UNNotificationDismissActionIdentifier){
...
//I need to do some coding here!
}
}
I use this for receiving remote notifications behind the scenes:
extension AppDelegate: UNUserNotificationCenterDelegate {
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
// Process this userInfo dictionary
processNotification(dictionary: userInfo)
}
In my willFinishLaunchingWithOptions in AppDelegate I call this:
fileprivate func setupAPN(application: UIApplication) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
// For iOS 10 data message (sent via FCM)
MobilePlatformPush.setRemoteDelegate(delegate: self)
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { _, _ in }
application.registerForRemoteNotifications()
}

I wanted to set up Firebase Cloud Messaging(FCM) for my iOS app. I followed the firebase documentation but I can't seem to get it to work. This is my app delegate file:
import UIKit
import Firebase
import FirebaseAnalytics
import FirebaseMessaging
#main
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {
let gcmMessageIDKey = "gcmMessageIDKey"
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FirebaseApp.configure()
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()
Messaging.messaging().delegate = self
return true
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: \(String(describing: 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.
}
// 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
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// ...
// Print full message.
print(userInfo)
// Change this to your preferred presentation option
completionHandler([[.banner, .sound]])
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: #escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
// ...
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print full message.
print(userInfo)
completionHandler()
}
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)
}
// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
}
I also set up the app capabilities:
capability setting
I also check many times that I have my APNs auth key right.
But when I tried to send a test notification from the firebase notification composer, nothing popped up on my phone. The function didReceiveRegistrationToken is working and provides a token, but when I used the token to 'send test message', nothing happened.
I tried to make an empty Xcode project side-by-side with the documentation to see if the issue is with my existing app, but it still didn't work.
Is there anything else that I'm missing here?
I need to get local notification data from lock screen or apps was kill. Is there a way to detect it or any handler that would trigger after show?.
i try using UNUserNotificationCenter present and UNUserNotificationCenter didReceive but still not working..
response.notification.request.content.userInfo contains the notification data
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
completionHandler()
guard let bodyText = response.notification.request.content.userInfo["body"] as? String else {return}
}
func application(_ application: UIApplication, didReceiveRemoteNotification
userInfo: [AnyHashable : Any])
{
if application.applicationState == .inactive || application.applicationState == .background
{
//opened from a push notification when the app was on background
}
}
I have managed to schedule a notification and show it to the user when the app is running/not running in the foreground. Now I need to display a ViewController upon the tap of this notification.
I understand that didReceiveRemoteNotification is the function that is called when the user taps on a notification. In my case, This function is never fired.
AppDelegate:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
return true
}
//didReceiveRemoteNotification goes here
The didReceiveRemoteNotification function:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
if ( application.applicationState == UIApplicationState.active)
{
print("Active")
// App is foreground and notification is recieved,
// Show a alert.
}
else if( application.applicationState == UIApplicationState.background)
{
print("Background")
// App is in background and notification is received,
// You can fetch required data here don't do anything with UI.
}
else if( application.applicationState == UIApplicationState.inactive)
{
print("Inactive")
// App came in foreground by used clicking on notification,
// Use userinfo for redirecting to specific view controller.
}
}
This is the entire Notification related code in my AppDelegate. Am I missing something?
For UserNotifications framework you need to work with UNUserNotificationCenterDelegate, so implement UNUserNotificationCenterDelegate with AppDelegate and set the delegate in didFinishLaunchingWithOptions method.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
return true
}
Now you need to implements userNotificationCenter(_:willPresent:withCompletionHandler:) and userNotificationCenter(_:didReceive:withCompletionHandler:) methods to get notification.
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
//Handle notification
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
// pull out the buried userInfo dictionary
let userInfo = response.notification.request.content.userInfo
if let customData = userInfo["customData"] as? String {
print("Custom data received: \(customData)")
switch response.actionIdentifier {
case UNNotificationDefaultActionIdentifier:
// the user swiped to unlock
print("Default identifier")
case "show":
// the user tapped our "show more info…" button
print("Show more information…")
break
default:
break
}
}
// you must call the completion handler when you're done
completionHandler()
}

I am trying to implement a basic func here which will be called when my app is backgrounded or suspended.
In reality, we aim to send about 5 a day so Apple should not throttle our utilisation.
I've put together the following which uses firebase and userNotifications, for now, it is in my app delegate.
import Firebase
import FirebaseMessaging
import UserNotifications
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var backgroundSessionCompletionHandler: (() -> Void)?
lazy var downloadsSession: Foundation.URLSession = {
let configuration = URLSessionConfiguration.background(withIdentifier: "bgSessionConfiguration")
configuration.timeoutIntervalForRequest = 30.0
let session = Foundation.URLSession(configuration: configuration, delegate: self, delegateQueue: nil)
return session
}()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FIRApp.configure()
if #available(iOS 10.0, *) {
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
// For iOS 10 data message (sent via FCM)
FIRMessaging.messaging().remoteMessageDelegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
let token = FIRInstanceID.instanceID().token()!
print("token is \(token) < ")
return true
}
func application(_ application: UIApplication, handleEventsForBackgroundURLSession identifier: String, completionHandler: #escaping () -> Void){
print("in handleEventsForBackgroundURLSession")
_ = self.downloadsSession
self.backgroundSessionCompletionHandler = completionHandler
}
//MARK: SyncFunc
func startDownload() {
NSLog("in startDownload func")
let todoEndpoint: String = "https://jsonplaceholder.typicode.com/todos/1"
guard let url = URL(string: todoEndpoint) else {
print("Error: cannot create URL")
return
}
// make the request
let task = downloadsSession.downloadTask(with: url)
task.resume()
NSLog(" ")
NSLog(" ")
}
func urlSessionDidFinishEvents(forBackgroundURLSession session: URLSession){
DispatchQueue.main.async(execute: {
self.backgroundSessionCompletionHandler?()
self.backgroundSessionCompletionHandler = nil
})
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
NSLog("in didReceiveRemoteNotification")
NSLog("%#", userInfo)
startDownload()
DispatchQueue.main.async {
completionHandler(UIBackgroundFetchResult.newData)
}
}
}
#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 message ID.
//print("Message ID: \(userInfo["gcm.message_id"]!)")
// Print full message.
print("%#", userInfo)
startDownload()
DispatchQueue.main.async {
completionHandler(UNNotificationPresentationOptions.alert)
}
}
*/
}
extension AppDelegate : FIRMessagingDelegate {
// Receive data message on iOS 10 devices.
func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
print("%#", remoteMessage.appData)
}
}
extension AppDelegate: URLSessionDownloadDelegate {
func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL){
NSLog("finished downloading")
}
}
The results are as follows:
When the app is in the foreground:
I get the log "in startDownload func"
I get the log "finished downloading".
When the app is in the background:
I get the log "in startDownload func"
I do not get the log "finished downloading".
The silencer isn't working i.e. when the app is backgrounded, I am still getting the notification in the tray.
I am using Postman to send the request and tried the following payload, which results in the console error 'FIRMessaging receiving notification in invalid state 2':
{
"to" : "Server_Key",
"content_available" : true,
"notification": {
"body": "Firebase Cloud Message29- BG CA1"
}
}
I have the capabilities set for background fetch and remote notifications. The app is written in swift 3 and uses the latest Firebase
EDIT: Updated AppDelegate to include funcs as per comment
A few observations:
When your app is restarted by handleEventsForBackgroundURLSessionIdentifier, you have to not only save the completion handler, but you actually have to start the session, too. You appear to be doing the former, but not the latter.
Also, you have to implement urlSessionDidFinishEvents(forBackgroundURLSession:) and call (and discard your reference to) that saved completion handler.
You appear to be doing a data task. But if you want background operation, it has to be download or upload task. [You have edited question to make it a download task.]
In userNotificationCenter(_:willPresent:completionHandler:), you don't ever call the completion handler that was passed to this method. So, when the 30 seconds (or whatever it is) expires, because you haven't called it, your app will be summarily terminated and all background requests will be canceled.
So, willPresent should call its completion handler as soon it done starting the requests. Don't confuse this completion handler (that you're done handling the notification) with the separate completion handler that is provided later to urlSessionDidFinishEvents (that you're done handling the the background URLSession events).
Your saved background session completion handler is not right. I'd suggest:
var backgroundSessionCompletionHandler: (() -> Void)?
When you save it, it is:
backgroundSessionCompletionHandler = completionHandler // note, no ()
And when you call it in urlSessionDidFinishEvents, it is:
DispatchQueue.main.async {
self.backgroundSessionCompletionHandler?()
self.backgroundSessionCompletionHandler = nil
}
Yesterday I updated 2 of my apps to swift 3.
func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
UIApplication.shared.registerForRemoteNotifications()
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print(error.localizedDescription)
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
// Save Installation if registered successfully
}
//MARK: Recieved Notification
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
print("received a notification")
}
so background push notification works fine on both apps, but in one of my app its not receiving any pushes in foreground that is, didReceiveRemoteNotification is never getting called
Things I have checked, Push Notifications enabled in Capabilities
Using this code to register for push notifications on both apps
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .alert, .sound], categories: nil))
Not only that, I have tried UNUserNotificationCenterDelegate for iOS 10 but still none of its delegate functions get called.
This only doesn't work on iOS 10 phones, iOS 8 and 9 works like charm.
So I'm not really sure why its never calling didReceiveRemoteNotification in only one of my 2 swift 3 apps on ios 10 when the app is open
This is my iOS 10 code I tried
//Added in didFinishLaunchingWithOptions
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
if error == nil{
UIApplication.shared.registerForRemoteNotifications()
}
}
}
//Delegates
#available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
print("push2")
}
#available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
print("push1")
}
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
self.initializeNotificationServices()
}
func initializeNotificationServices() -> Void {
if #available(iOS 10.0, *) {
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
if granted {
//self.registerCategory()
//self.scheduleNotification("test", interval: 3)
//self.scheduleNotification("test2", interval: 5)
let types : UIUserNotificationType = [.Badge, .Sound, .Alert]
let mySettings : UIUserNotificationSettings = UIUserNotificationSettings.init(forTypes: types, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(mySettings)
UIApplication.sharedApplication().registerForRemoteNotifications()
}
}
}
else {
// Fallback on earlier versions
let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
// This is an asynchronous method to retrieve a Device Token
// Callbacks are in AppDelegate.swift
// Success = didRegisterForRemoteNotificationsWithDeviceToken
// Fail = didFailToRegisterForRemoteNotificationsWithError
UIApplication.sharedApplication().registerForRemoteNotifications()
}
}
#available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
print("willPresent")
completionHandler([.Badge, .Alert, .Sound])
}
#available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
self.didReceiveBookingAppRemoteNotification(response.notification.request.content.userInfo)
print("didReceive == >> \(response.notification.request.content.userInfo)")
completionHandler()
}
//for Lower to ios 10 version
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
self.getNotifInfo(userInfo)
}
Make sure you have to enable push notification from project's
Target => Capabilities and you have to add it's framework UserNotifications.framework
