I have properly set up location based local notifications. As of now the user receives a notification when they enter a defined zone (CLCircularRegion). Id like to delay that notification about 10 minutes after they enter the zone, could that be possible?
// SENDING WITH (UNLocationNotificationTrigger)
let trigger = UNLocationNotificationTrigger(region: destRegion, repeats: false)
let request = UNNotificationRequest(identifier: notificationInfo.notificationId,
content: notification,
trigger: trigger)
UNUserNotificationCenter.current().add(request)
I also send notification locally for other reasons at different places in my app. This causes a delay for the elapsedSeconds.
// SENDING WITH (UNTimeIntervalNotificationTrigger)
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: elapsedSeconds, repeats: false)
let request = UNNotificationRequest(identifier: "cartabandon", content: localnotification, trigger: trigger)
UNUserNotificationCenter.current().add(request)
Maybe theres a way to combine the two? Or another option?

I'm trying to group different local notifications together, but iOS 15.2 seems to ignore the threadIdentifier parameter and it stills display the notifications in separate rows:
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
let notificationContent = UNMutableNotificationContent()
// ... more properties
notificationContent.threadIdentifier = "please-group-together" // not working
let request = UNNotificationRequest(identifier: UUID().uuidString, content: notificationContent, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: completion)
Am I missing something?
Is it possible to trigger Notification Service Extension through Local Push Notification?
My code snippet
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
let content = UNMutableNotificationContent()
// Adding title,subtitle,body & badge
content.title = "title"
content.body = "body"
content.sound = UNNotificationSound.default
let aps = ["mutable-content": 1]
let dict = ["aps": aps, "some-key": "some-value"] as [AnyHashable : Any]
content.userInfo = dict
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 10, repeats: false)
let request = UNNotificationRequest(identifier: "SimplifiedIOSNotification", content: content as UNNotificationContent, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
No, It is not possible to trigger notification service extension through push notification.
Reason: Service extension lets you customize the content of a remote notification before it is delivered to the user. e.g decrypt the message or download the attachments
but I personally think there is no point of downloading the notification content attachments in service extension because you can always download the attachments before scheduling. e.g
// Download attachment asynchronously
downloadAttachments(data: data) { attachments in
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
let content = UNMutableNotificationContent()
// Add downloaded attachment here
content.attachments = attachments
// Adding title,subtitle,body & badge
content.title = "title"
content.body = "body"
content.sound = UNNotificationSound.default
// No need of adding mutable content here
let dict = ["some-key": "some-value"] as [AnyHashable : Any]
content.userInfo = dict
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 10, repeats: false)
let request = UNNotificationRequest(identifier: "SimplifiedIOSNotification", content: content as UNNotificationContent, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}
Let me know if you have different use case.
Pleas read the documentation before posting. The first line states:
A UNNotificationServiceExtension object provides the entry point for a Notification Service app extension, which lets you customize the content of a remote notification before it is delivered to the user.
My iOS app has a share-extension where users can also upload Attachments.
As those can be large, the upload is done using an URLSession with URLSessionConfiguration.background. After the upload is done, I'd like to show the user some kind of success-ui and chose a Notification for that purpose. So now in my completion block I am doing something like that:
let content = UNMutableNotificationContent()
content.body = "Success"
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 0.5, repeats: false)
let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
let center = UNUserNotificationCenter.current()
center.add(request)
print("This line is never called")
and as you can see in my sample code here, the app is stuck ad center.add(request). This method is just never completing?!? When calling it, I am on the main-thread, but also tried on other threads... always the same result
Does anybody have an idea why?
I have an messaging app,I am using VoIP notifications to send acknowledgement to users. I am firing a local notification each time the PushKit delegate is called.
The current scenario is that the previous notification gets removed and is replaced by a newer one. Is there a way to manage local notifications such that the user can see multiple notifications in their device?
This is the code I have tried:
let notificationContent = UNMutableNotificationContent()
notificationContent.title = "Title"
notificationContent.subtitle = "Subtitle"
notificationContent.body = "Body"
// Add Trigger
let notificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: 0.01, repeats: false)
// Create Notification Request
let notificationRequest = UNNotificationRequest(identifier: "cocoacasts_local_notification", content: notificationContent, trigger: notificationTrigger)
// Add Request to User Notification Center
UNUserNotificationCenter.current().add(notificationRequest) { (error) in
if let error = error {
print("Unable to Add Notification Request (\(error), \(error.localizedDescription))")
}
}
P.S : I don't want to schedule local notification for a later period
Using for loop to register multiple Notification with the unique identifier https://developer.apple.com/documentation/usernotifications/unnotificationrequest/1649634-identifier?language=objc
let notificationRequest = UNNotificationRequest(identifier: "cocoacasts_local_notification", content: notificationContent, trigger: notificationTrigger)
you should change this identifier "cocoacasts_local_notification" to dynamically reset the unique identifier
let notification = UNMutableNotificationContent()
let notificationTrigger = UNCalendarNotificationTrigger(dateMatching: dayComponent, repeats: true)
let lnMessageId:String = messageDict["Id"] as! String
let dayRequest = UNNotificationRequest(identifier: lnMessageId , content: notification, trigger: notificationTrigger)
UNUserNotificationCenter.current().add(dayRequest, withCompletionHandler: {(_ error: Error?) -> Void in
if error == nil
{
//print("success")
}
else
{
//print("UNUserNotificationCenter Error : \(String(describing: error?.localizedDescription))")
}
})
I am setting up my local notification using the following code. The issue I am facing is that it triggers the "will present" delegate call back just after the execution of this code and don't wait for the interval. i.e. 2 minutes. then trigger again after 2 minutes as required. I am new to this.
let content = UNMutableNotificationContent()
let center = UNUserNotificationCenter.current()
center.removeAllPendingNotificationRequests()
let message = String(format: "No hit since %d minutes", notificationInterval!)
content.body = message
content.sound = UNNotificationSound.default()
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: TimeInterval(2 * 60), repeats: true)
let request = UNNotificationRequest(identifier: "liveSessionLocalNotification", content: content, trigger: trigger)
// Schedule the notification.
center.add(request) { (error) in
}
