In iOS 11, how can I implement a local notification which repeats every x minutes?
The repeating interval will be selected from the user. So for example let's say that a user choose to set a notification which will trigger tomorrow at 9:00 AM and from there it triggers every 2 days (or two weeks or 6 months or 10 minutes)
var repeatInterval = Bool()
trigger = UNCalendarNotificationTrigger(dateMatching: triggerDate, repeats: repeatInterval)
//Schedule the Notification
let identifier = titleNospace
let request = UNNotificationRequest(identifier: identifier!, content: content, trigger: trigger)
self.center.add(request, withCompletionHandler: { (error) in
if let error = error {
print(error.localizedDescription)
}
})
UNUserNotificationCenter.current().add(notificationRequest, withCompletionHandler: nil)
With this code I can schedule a notification at a set date. I've been told that from here if I would like to schedule a repeat notification I should use a triggerInterval when the notification is delivered.
But how can I do so? How can I get the value of the repeating time (defined by the user) when the notification is delivered?
Shall I use this?:
func didReceive(_ notification: UNNotification)
I've tried but it seems that it's never called.
I'm new to swift and I've tried and tried but it seems I cannot find a solution.
I've been able to manage the repeating hourly, monthly, daily and yearly.
If I would like to add a custom repeat though I really wouldn't know how to do.
For your information you can't do customise repeat time interval like every 2 min, 10 min or Etc. you must use value of NSCalendarUnit like

I want to when user get notification from fcm (Firebase Cloud Messaging) or scheduler local notification like alarm notification like image below :
Here my code :
func onTest() {
let content = UNMutableNotificationContent()
content.title = "Weekly Staff Meeting"
content.body = "Every Tuesday at 2pm"
// Configure the recurring date.
var dateComponents = DateComponents()
dateComponents.calendar = Calendar.current
dateComponents.hour = 16 // 14:00 hours
dateComponents.minute = 11
// Create the trigger as a repeating event.
let trigger = UNCalendarNotificationTrigger(
dateMatching: dateComponents, repeats: true)
// Create the request
let uuidString = UUID().uuidString
let request = UNNotificationRequest(identifier: uuidString,
content: content, trigger: trigger)
// Schedule the request with the system.
let notificationCenter = UNUserNotificationCenter.current()
notificationCenter.add(request) { (error) in
if error != nil {
// Handle any errors.
}
}
}
My code right now just like the usual notification which disappears in 5 seconds I want to make it like an Alarm notification or Whatsapp Calling Notification. Please Help Thanks.
Due to Apple's limitation, app dev can only play notification tone up to 30 seconds. It will play default notification tone if your tone is longer than 30 seconds.
If your notification tone is gone after 5 seconds, try to set your notification presentation options to list, badge and sound.
Once there's no banner for notification, your 30seconds tone will play till the end.
Unfortunately there's no legal way or any workaround to have notification ring continuously such as alarm clock. Hope I was wrong though.

What I think, max you can do is to present a local notification. But yes that would not be exactly like an Apple Alarm notification. In Reality, you don't have permission for this. You can only present the local notifications.
Since UILocalNotification was deprecated in iOS10, I'm having trouble understanding how to update the following code to the UNNotificationRequest framework. Im basically letting a user schedule a daily notification at a time of their choosing. For example, if they want to get a notification everyday at 11:00AM. The below code works for iOS versions below iOS10 but since UILocalNotification is deprecated, it no longer works. Any help is greatly appreciated.
let notification = UILocalNotification()
notification.fireDate = fixedNotificationDate(datePicker.date)
notification.alertBody = "Your daily alert is ready for you!"
notification.timeZone = TimeZone.current
notification.repeatInterval = NSCalendar.Unit.day
notification.applicationIconBadgeNumber = 1
UIApplication.shared.scheduleLocalNotification(notification)
You can use UNCalendarNotificationTrigger for creating a notification that fires repeatedly using UNUserNotificationCenter. You can do something like this. The trick is to only have the time component in the Trigger date.
let center = UNUserNotificationCenter.current()
let content = UNMutableNotificationContent()
content.title = "Attention!"
content.body = "Your daily alert is ready for you!"
content.sound = UNNotificationSound.default
let identifier = "com.yourdomain.notificationIdentifier"
var triggerDate = DateComponents()
triggerDate.hour = 18
triggerDate.minute = 30
let trigger = UNCalendarNotificationTrigger(dateMatching: triggerDate, repeats: true)
let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)
center.add(request, withCompletionHandler: { (error) in
if let error = error {
// Something went wrong
print("Error : \(error.localizedDescription)")
} else {
// Something went right
print("Success")
}
})
You can't schedule a notification that repeats daily. That notification would happen only once, and then you would have to schedule it again, which means that you would have to open the app again.
There is BGTask API introduces in iOS 13, that can be used to perform some background tasks, but not this one, you can not schedule the task for specific time.This API last only works when app is in the background, not when it is killed. You can only set some time interval that the system will use as a guiding point to determine when to perform you app's code. But in my experience it is pretty unreliable.
The only way to achieve this is to implement remote push notifications. Push notifications also work even when the app is killed.
Im trying to schedule local notification every hour. The problem is that im getting the notification in such irregular time. Sometime in 10 minutes, or in second, or 30 minutes. Sometime i get like 10 notifications in the same second suddenly. I have no idea what is the mistake im doing here. I apologize in advance, i just started learning swift.
This is my code.
#objc func LocalNotificationHour() {
let user = UNUserNotificationCenter.current()
user.requestAuthorization(options: [.alert,.sound]) { (granted, error) in}
let content = UNMutableNotificationContent()
content.title = "Local Notification"
content.body = "Test."
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: (60*60), repeats: true)
let uuid = UUID().uuidString
let request = UNNotificationRequest(identifier: uuid, content: content, trigger: trigger)
user.add(request) { (error) in print("Error")}
}
Is it possible that your function is being run multiple times, and therefore scheduling more than one notification to repeat? That would account for receiving multiple notifications at once/at times when you're not expecting them.
If that is the case, try adding the line user.removeAllPendingNotificationRequests() under let user = UNUserNotificationCenter.current(). This will remove any pending notifications your app may have scheduled before scheduling a new one.
It's because you are running your code once with one hour logic.
And then you are changing logic for two hour logic.
So basically both notification is triggering.
Either delete the app or previously scheduled notifications or change the identifier.
Hello to all I'm stuck with one issue in my iOS app. I have searched over the internet and didn't find solution. Most of the solutions are using deprecated
func application(_ application: UIApplication, didReceive notification: UILocalNotification)
So scenario is following:
App schedules for each day 5 local notifications and that is okay and that works:
var dateComponents = DateComponents()
dateComponents.weekday = Date().dayNumberOfWeek()
dateComponents.hour = hour
dateComponents.minute = minute
dateComponents.second = 5
let notificationTrigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: false)
let request = UNNotificationRequest(identifier: "identifier", content: notifcation, trigger: notificationTrigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
But my question is: is it possible to find out when notification is fired regardless of app state and get data from that notification?
Because time for each notification is retrieved from API I don't know when (hour and minute) notifications will be scheduled.
For example in Android I schedule notifications using AlarmManager API and than easly by extending BroadcastReciver I can fetch every fired notification and get data sent via Intent.
I need to find out when last (fifth) notification is fired for that day so I can preform some additional work.
In short no, it's not possible to be notified regardless of the app state.
If the app is running in foreground you can do this using UNUserNotificationCenterDelegate methods, but if your app is not in foreground the app will know about the notification only if it's opened from the notification (swiping or tapping it).
Basically, I need an app that runs a notification every other Monday. What I have is an app that runs a notification every Monday. Is there a way to set it up so that when the first notification is received the app will begin a two week time interval where it will run the notification again, and have it repeat? For example, if I had a variable called "week" and had it alternate between '1' and '2' every other week, how could I tag it to the notification's trigger?
func notification(hour: Int, minute: Int, weekday: Int, text: String){
let content = UNMutableNotificationContent()
content.title = "Example"
content.body = text
content.sound = UNNotificationSound.default()
let trigger = UNCalendarNotificationTrigger(dateMatching: DateComponents(hour: hour, minute: minute, weekday: weekday), repeats: true)
let request = UNNotificationRequest(identifier: text, content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
notification(hour: 12, minute: 0, weekday: 2, text: "Test")
}
You cannot do that for repeated notifications.
Only way to do this is to use non-repeated notifications and setup them on given time (in your case on Mondays) in advance - for example make a for-loop that will setup single notification on next 10 Mondays - you have to manually calculate trigger time for all of them in a loop.
Limitation is that you cannot make them infinitive - but probably if user will not react to those 10 notifications - there is a really small chance you use them later on - at least from my experience.
Best way to do this will be also to setup those notifications each time user closes the application - if we opens the app on 5th Monday for example, you should clean up all notifications and setup next set of 10 notifications again.
