(iOS) Cancelling all local notifications when app is no longer running

I'm working on an app that is too complex to fully explain, so to support my question I will provide a very basic example of what I'm trying to achieve.

Say I have an app that shows a timer of 10 minutes. If a button is pressed, the timer runs down to 0. When the app is closed (not terminated), I want to notify the user of this by a local notification.

When the app gets terminated, the timer obviously stops as well. However, the local notification would still be set up and fired eventually.

I don't want this to happen. I only want to show the notification if the app is still running in the background. If the app gets terminated by the user or by a crash, the notification should not appear.

Is there any way of achieving this?

Thanks in advance guys.

Laurens

You can check the state of your app where you setup and show your local notification:

Swift 3

let state = UIApplication.shared.applicationState
if state == .background {
    print("App in Background")
}
