iOS object memory warning

[Olivier]

As you know, iOS might terminate any app running in the background if it needs to free up memory. That's why I would like to know if the condition "Application has received a memory warning" of the iOS object also fires when the app is in the background. If yes I could make my app react accordingly, like writing data.

That is a very good question. We will do some testing (but you can do it too) : drop a counter on the frame, and in case of memory message, add one to it.
Then put the app in the back and eat memory. If the counter has changed when you revive the app, then the answer is yes.
