How to clear the remote notification in your app?

Question

Is there a way to clear the remote notification from the notification banner when swiping down from the top of the iPhone screen. I tried setting the badge number to zero:

Answer 1

I have to increment then decrement badge count in order for it to work:

application.applicationIconBadgeNumber = 1
application.applicationIconBadgeNumber = 0
application.cancelAllLocalNotifications()
