Not getting didReceiveMemoryWarning when app is in the background

Question

I\'m noticing that my view controllers aren\'t getting their didReceiveMemoryWarning methods called when my application is in the background state on the iPad s

Answer 1

I don't think that is the case. I am able to access didReceiveMemoryWarning code while in background. Once system generates low memory signal than as a good citizen we should release the memory. This also helps our app from terminating by the system.

Answer 2

If you did not start a background task, or do VOIP, location tracking or audio in the background, then your app is suspended after applicationDidEnterBackground. It will not get any notifications. Any notifications are kept around (even those that occur after the app was suspended) and sent to the app when the app goes to the foreground again.
