<code>UIApplication.sharedApplication().cancelAllLocalNotifications()</code>

For cancelling all pending notifications, you can use this:

<pre><code>UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
</code></pre>

For cancelling specific notifications,

<pre><code>UNUserNotificationCenter.current().getPendingNotificationRequests { (notificationRequests) in
 var identifiers: [String] = []
 for notification:UNNotificationRequest in notificationRequests {
 if notification.identifier == "identifierCancel" {
 identifiers.append(notification.identifier)
 }
 }
 UNUserNotificationCenter.current().removePendingNotificationRequests(withIdentifiers: identifiers)
}
</code></pre>

blocks|key|4039006|text|识别相同+UNNotification的方式是基于创建identifier时传递的UNNotificationRequest。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4039007|在上面的示例中，|4039008|let+request+=+UNNotificationRequest(identifier:+"myNotif",+content:+notif,+trigger:+dateTrigger)|code-block|syntax|javascript|4039009|实际上，您已经将identifier硬编码为"myNotif"。这样，当您想要删除已设置的通知时，您可以这样做：|4039010|UNUserNotificationCenter.current().removePendingNotificationRequests(withIdentifiers:+"myNotif")|4039011|但是，请注意，当您对标识符进行硬编码时，每次向UNUserNotificationCenter添加request时，通知实际上都会被替换。|4039012|例如，如果您在1分钟后安排了一个"myNotif"+request设置，但您调用另一个函数在1小时后安排了一个"myNotif"，则它将被替换。因此，只有一小时后的最新"myNotif"将在pendingNotificationRequest中。|4039013|entityMap^0|5|E|R|A|15|L|0|0|0|8|A|M|9|0|0|N|O|1D|7|0|G|9|Q|7|1J|9|2C|9|2N|Q|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]|$9|Z|A|10|B|C]|$9|11|A|12|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|13|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|14|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|15|8|@$9|16|A|17|B|C]|$9|18|A|19|B|C]]|D|@]|E|$]]|$1|O|3|P|5|J|7|1A|8|@]|D|@]|E|$K|L]]|$1|Q|3|R|5|6|7|1B|8|@$9|1C|A|1D|B|C]|$9|1E|A|1F|B|C]]|D|@]|E|$]]|$1|S|3|T|5|6|7|1G|8|@$9|1H|A|1I|B|C]|$9|1J|A|1K|B|C]|$9|1L|A|1M|B|C]|$9|1N|A|1O|B|C]|$9|1P|A|1Q|B|C]]|D|@]|E|$]]|$1|U|3|-4|5|6|7|1R|8|@]|D|@]|E|$]]]|V|$]]

The way same <code>UNNotification</code> is identify are base on the <code>identifier</code> passed when you create the <code>UNNotificationRequest</code>.

In your example above,

<pre><code>let request = UNNotificationRequest(identifier: "myNotif", content: notif, trigger: dateTrigger)
</code></pre>

You have actually hardcoded the <code>identifier</code> to be <code>"myNotif"</code>. This way, whenever you want to delete the already set notification you can do this:

<pre><code>UNUserNotificationCenter.current().removePendingNotificationRequests(withIdentifiers: "myNotif")
</code></pre>

However, do take note that when you hardcode the identifier, every time when you add a <code>request</code> to <code>UNUserNotificationCenter</code> the notification is actually being replaced. 

Example, if you scheduled a <code>"myNotif"</code> <code>request</code> set on 1 minute later but you call another function to schedule a <code>"myNotif"</code> at 1 hour later it will be replaced. Therefore only the latest <code>"myNotif"</code> at one hour later will be in the <code>pendingNotificationRequest</code>.

How I can disable/cancel already setted notification? 

Here is my schedule function.

<pre><code>func scheduleNotif(date: DateComponents, completion: @escaping (_ Success: Bool) -&gt; ()) {

 let notif = UNMutableNotificationContent()

 notif.title = "Your quote for today is ready."
 notif.body = "Click here to open an app."

 let dateTrigger = UNCalendarNotificationTrigger(dateMatching: date, repeats: true)
 let request = UNNotificationRequest(identifier: "myNotif", content: notif, trigger: dateTrigger)

 UNUserNotificationCenter.current().add(request, withCompletionHandler: { error in

 if error != nil {
 print(error)
 completion(false)
 } else {
 completion(true)
 }
 })
}
</code></pre>
