Local notifications are not firing in ios10

Question

I\'m using UNUserNotificationCenter for ios 10. For testing, I\'m setting a local notification for 10 seconds from current time.

This is what I tried,

Answer 1

Set NSDateComponents like:

NSDateComponents *components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay|NSCalendarUnitHour|NSCalendarUnitMinute|NSCalendarUnitSecond|NSCalendarUnitTimeZone fromDate:[[NSDate date] dateByAddingTimeInterval:10]];

Answer 2

Or use a time trigger instead of a calendar trigger

Answer 3

@IBAction func sendNotification(_ sender: Any) {

    let content = UNMutableNotificationContent()
    content.title = "Hello"
    content.body = "Ved Rauniyar !!!"
   // content.badge = 1
    content.sound = UNNotificationSound.default()
    // Deliver the notification in five seconds.
    let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)
    let url = Bundle.main.url(forResource:"ved", withExtension: "png")
    let attachment = try? UNNotificationAttachment(identifier: "FiveSecond",
                                                   url: url!,
                                                   options: [:])
    content.attachments = [attachment!]
    let request = UNNotificationRequest.init(identifier: "FiveSecond", content: content, trigger: trigger)
    // Schedule the notification.
    let center = UNUserNotificationCenter.current()
    center.add(request) { (error) in
       // print(error!)
    }
}
