title: Is it possible to trigger a local notification after an event IOS?
body: <p>Im working on an app that does some computationally heavy tasks that take a long time. I want to notify the user with a local push notification when the task is done. Is this possible? The only information I have been able to find online is to do with triggering notifications at certain times/dates or if the app has entered the background or terminated, all of which is done in the appDelegate. Is there a way to do this in my own classes? </p>
  
  <p>Thanks.</p>
