I have a trigger to show a notification to the user:
let content = UNMutableNotificationContent()
content.title = "Title"
content.body = "Body"
content.sound = UNNotificationSound.default
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 20, repeats: false)
let request = UNNotificationRequest(identifier: "TestIdentifier", content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
Is there a way for me to cancel that trigger once it has been set?
How do I cancel the notification before the timeInterval runs out and call the notification?
You can cancel or remove notifications by calling:
let center = UNUserNotificationCenter.current()
Remove pending notifications with given identifier
center.removePendingNotificationRequests(withIdentifiers: [“givenIdentifier”])
And remove delivered notifications with given identifier
center.removeDeliveredNotifications(withIdentifiers: [“givenIdentifier”])
To build on top of Mannopson's answer:
This removes all pending Notifications (Swift 5)
func cancelNotifications() -> Void {
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
}
