I used local notification to deliver a message to the user at the same time I want to update App badge when the notification triggers, but the local notification delegate have functions that deal with notifications when the app is in the foreground and when the user interacts with notification (like a tap on it). Is there any way to update the app badge when the notification triggers and the app is in background?
Handle notification when the app is in the foreground
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
// run code when app in foreground
}
Handle notification when the tap action on it
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
// run code when user interact with notification only
}
To update App badge when local notification trigger set the badge value in the code bellow when set the notification:
func schedulNotification() {
let content = UNMutableNotificationContent()
content.badge = 1 // That will appear on app icon when notification trigger
// Continue notification settings...
}

Able to store push notification data when app is in foreground and background(when launch notification).
But not on application killed or inactive state in iOS.
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound, .badge])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
defer { completionHandler() }
guard response.actionIdentifier == UNNotificationDefaultActionIdentifier else { return }
// perform action here
}
WillPresent is calling when application is in open state,
did receive is calling when user taps on notification.
In these scenarios able to save notification data.
How to save data When application killed and when no interaction with notification.
How to achieve this ?
I am using didReceiveRemoteNotification for detecting the app notification. But it is is getting fired automatically, when the app is at running state. I need the notification selection get detected when the app is at running state, rather than automatic notification detection through didReceiveRemoteNotification. Thanks in Advance
iOS 10+ provide the custom local notification for handling this type of issue when the app is running in the foreground.
In didFinishLaunchingWithOptions, add the delegate
UNUserNotificationCenter.current().delegate = self
then create an appDelegate extension and add this.
#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 full message.
print(userInfo)
// Change this to your preferred presentation option
completionHandler([.alert,.sound])
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: #escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
// Print full message.
print("tap on on forground app",userInfo)
completionHandler()
}
}

I have implemented push notification for ios10. Tapping on the notification alert would trigger "didReceive" delegate, were i save the notification in coredata or silent notification if i m in foreground. The problem is if i receive a stack of notification in background and When i bring my app to foreground from background, Is there a possibility to call "didReceive" delegate or any other push notification delegate were i could sync my items to coredata.
Note
I don't want to sync(didReceive or any delegate) the items in background using silent notification nor tapping on the alert. It should sync automatically the stack of push notification when i bring the app to foreground
func handleInboxNotification(didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
if let inboxValue = userInfo["inbox"] as? String, let value = inboxValue.boolValue(), value {
let mappedMessage = MessageCenterSDK.shared.constructReorderedDictionary(userInfo: userInfo)
MessageCenterDataManager.shared.synchronize(messages: mappedMessage)
messageCenterDelegate?.didFindNewMessages(hasNewMessages: true)
}
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: #escaping () -> Void) {
/// Handle outbound remote
handleInboxNotification(didReceiveRemoteNotification: response.notification.request.content.userInfo)
completionHandler()
}
I was facing the same issue, but my target was for iOS 13 & I'm using BGTaskScheduler to fetch data from the server in the background as well in terminated state.
I too want to trigger the notification when the app is in background. But not tapped but that seems to be not possible so we have changed our implementation by enabling background mode and it worked for me.
Hope it also helps.
For more reference on BGTaskScheduler, https://developer.apple.com/documentation/backgroundtasks/bgtaskscheduler
you need to use willpresent delegate in appDelegate
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
// Change this to your preferred presentation option
completionHandler([])
}
This delegate is called when a notification comes in foreground
I have to locally store Title and Body of all the notifications coming in my iOS app and display those in a notifications screen. I'm able to store all the notification tapped by using these-
This gets called when the app is in not running state or killed when the push notification is tapped-
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {...}
This gets called when app is running in foreground or background and push notification is tapped-
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: #escaping () -> Void) {...}
My question is how to store notifications without tapping on notifications.
I want to store the notifications even if the notification is dimissed/cleared by user.
I know this method is called when app is active and in the foreground and push notification comes-
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {..}
How to handle push notification data without tapping on it when the app is in background or not running state?
1- If the app isn't running then no way to wake up the app only with ( VOIP )
2- if in background then add this key to the sended payload
"content_available": true
And enable RemoteNotifications from app capabilities
I am writing a reminder app in iOS 10; my local notifications are send using the UserNotifications framework. Sending the notification works fine already; my problem is rather the background handling of the notification.
Earlier days, you could use didReceiveRemoteNotification in the app delegate for handling stuff like userInfo; now, UserNotification has apparently it's own methods.
I want to detect, generally, if in my absence a notification has arrived. Case: I received it, I tap open the app icon, bam: alert controller that says: you've received a notification.
I am using these both functions for it:
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (_ options: UNNotificationPresentationOptions) -> Void) {
print("Handle push from foreground")
UserDefaults.standard.set(true, forKey: "didReceiveRemoteNotification")
UserDefaults.standard.synchronize()
print("\(notification.request.content.userInfo)")
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
print("Handle push from background or closed")
UserDefaults.standard.set(true, forKey: "didReceiveRemoteNotification")
print("\(response.notification.request.content.userInfo)")
}
But they ONLY work, if I access the app by tapping on the notification in Notification Center. So, how do I detect if I've received a notification in the scenario that I don't enter the app through the notification, but through the app itself?
