cancelAllLocalNotifications not working in iOS10

Question

I want to remove all previous local notification from NotificationCenter when adding new notifications. But it is working in iOS9.0 and lower version but in iOS 10 it fires

Answer 1

For iOS 10, Objective C:

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center removeAllDeliveredNotifications];
[center removeAllPendingNotificationRequests];

Swift 4:

UNUserNotificationCenter.current().removeAllPendingNotificationRequests()

If you want to list all notifications:

func listPendingNotifications() {

    let notifCenter = UNUserNotificationCenter.current()
    notifCenter.getPendingNotificationRequests(completionHandler: { requests in
        for request in requests {
            print(request)
        }
    })
}

Answer 2

For iOS 10, Swift 3.0

cancelAllLocalNotifications deprecated from iOS 10.

@available(iOS, introduced: 4.0, deprecated: 10.0, message: "Use UserNotifications Framework's -[UNUserNotificationCenter removeAllPendingNotificationRequests]")
open func cancelAllLocalNotifications()

You will have to add this import statement,

import UserNotifications

Get notification center. And perform the operation like below

let center = UNUserNotificationCenter.current()
center.removeAllDeliveredNotifications() // To remove all delivered notifications
center.removeAllPendingNotificationRequests() // To remove all pending notifications which are not delivered yet but scheduled.

If you want to remove single or multiple specific notification, you can achieve it by below method.

center.removeDeliveredNotifications(withIdentifiers: ["your notification identifier"])

Hope it helps..!!

For iOS 10, You can use this way for removing all of Local Notification. I have just tested, It's working.

    NSArray *arrayOfLocalNotifications = [[UIApplication sharedApplication] scheduledLocalNotifications] ;
    for (UILocalNotification *localNotification in arrayOfLocalNotifications) {
        [[UIApplication sharedApplication] cancelLocalNotification:localNotification] ;
    }
