swift ios check if local notification is show - swift

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
}
}

Handle notification dismiss action when app is on the background

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()
}

Debugging Firebase with Swift 3

I'm trying to debug why I can't get messages from firebase on my iPhone,
I am connected to the FCM server, and I've also subscribed to a topic, however, when I try to print data recieved from FCM I get nil values.
This is the code I have from google's tutorial, it gets executed so that does mean the app is being notified correctly that a new topic is available on FCM?
Also how can I debug to see if there's something I'm doing wrong in setting FCM up?
Thanks
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
// Print message ID.
FIRMessaging.messaging().subscribe(toTopic: "/topics/newNotificationtest")
print("Message ID: \(userInfo["gcm.message_id"])")
debugPrint(userInfo)
// Print full message.
print("%#", userInfo)
}
Please Try With this code and debug
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
FIRMessaging.messaging().appDidReceiveMessage(userInfo)
let aps = userInfo["aps"] as? NSDictionary
print(aps)
print(userInfo)
print("Message ID: \(userInfo["gcm.message_id"]!)")
print("%#", userInfo)
}

How do I handle ios push notifications when the app is in the foreground?

How do I set up my AppDelegate to handle push notifications that occur when the app is in the foreground and in the background with swift 3 and ios 10? Including how to make the phone vibrate while in the foreground if I receive a notifcation.
Here is how I set up my AppDelegate file to do this:
To handle push notifications, import the following framework:
import UserNotifications
To make the phone vibrate on any device import the following framework:
import AudioToolbox
Make your AppDelegate a UNUserNotificationCenterDelegate:
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
In your "didFinishLaunchingWithOptions" add this:
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(granted, error) in
if (granted) {
UIApplication.shared.registerForRemoteNotifications()
} else{
print("Notification permissions not granted")
}
})
This will determine if the user has previously said that your app can send notifications. If not, handle it how you please.
To get access to the device token once it is registered:
//Completed registering for notifications. Store the device token to be saved later
func application( _ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data ) {
self.deviceTokenString = deviceToken.hexString
}
hexString is an extension I added to my project:
extension Data {
var hexString: String {
return map { String(format: "%02.2hhx", arguments: [$0]) }.joined()
}
}
To handle what happens when your app receives a notification in the foreground:
//Called when a notification is delivered to a foreground app.
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
//Handle the notification
//This will get the text sent in your notification
let body = notification.request.content.body
//This works for iphone 7 and above using haptic feedback
let feedbackGenerator = UINotificationFeedbackGenerator()
feedbackGenerator.notificationOccurred(.success)
//This works for all devices. Choose one or the other.
AudioServicesPlayAlertSoundWithCompletion(SystemSoundID(kSystemSoundID_Vibrate), nil)
}
To handle what happens when a users presses on a notification they receive (from your application) while your app is in the background, call the following function:
//Called when a notification is interacted with for a background app.
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
//Handle the notification
print("did receive")
let body = response.notification.request.content.body
completionHandler()
}
I would add to havak5's answer that you can set push notifications to be shown as iOS default push, just like this:
swift code:
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
if UIApplication.shared.applicationState == .active {
completionHandler( [.alert,.sound]) // completionHandler will show alert and sound from foreground app, just like a push that is shown from background app
}
}

Swift 3 - Local Notification's didReceiveRemoteNotification function not fired

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()
}

Push not received on iOS 10 when the app is in foreground

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
