Dismiss IOS Notification from NotificationContentExtention

Question

Is it possible to dismiss/cancel a local notification from a button with in NotificationContentExtension?

I was only able to dismiss the NotificationContentExtension itself, but not the entire notification.

if #available(iOSApplicationExtension 12.0, *) {
          self.extensionContext?.dismissNotificationContentExtension()
}

Вы можете сделать это с помощью протокола UNUserNotificationCenter и UNNotificationContentExtension.

Добавить действие с помощью UNUserNotificationCenter

let center = UNUserNotificationCenter.current()
center.delegate = self  
center.requestAuthorization (options: [.alert, .sound]) {(_, _) in 
}  
let clearAction = UNNotificationAction(identifier: "ClearNotif", title: "Clear", options: [])
let category = UNNotificationCategory(identifier: "ClearNotifCategory", actions: [clearAction], intentIdentifiers: [], options: [])
 center.setNotificationCategories([category])

Добавьте метод делегата протокола UNNotificationContentExtension в контроллер представления вашего расширения

 func didReceive(_ response: UNNotificationResponse, completionHandler completion: @escaping (UNNotificationContentExtensionResponseOption) -> Void) {
    if response.actionIdentifier == "ClearNotif" {
        UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
        UNUserNotificationCenter.current().removeAllDeliveredNotifications()
    }
    completion(.dismiss)
}

Попробуйте и дайте мне знать, что это работает.
