iOS notification app goes into background doesn't seem to work

[Graham Samuel]

Thanks to Mark Smith and Henry Lowe, I know that I’m supposed to set up mergNotify for two notifications as below.

I believe I’ve done this, and I’ve set a monitoring action (putting a text into a field) to show that these notifications have happened.

Of course it may be just me, but so far, I only seem to get the notification when the app comes back into the foreground (so logically it must have gone the background first),  but I just don’t get the ‘going in to the background' notification, or at least my monitoring doesn’t work.  Is there some trick of timing that I’ve missed?

It’s documented under mergNotify in the dictionary (with credit to Elanor for pointing this out to me when my “on shutdownRequest” handlers were being ignored).
