When I plug in the iPhone to iTunes and drag a file into the File Sharing section of my app, the app on the screen goes away for a moment and then comes back. It seems that none of the app delegate methods are triggered at this time, not even something like "went to background, went to foreground".
As soon as my app comes back after a sync where the user added or removed files, I want to update the screen.
Maybe there is a notification beeing sent?
- (void)applicationWillResignActive:(UIApplication *)application
is called when the sync starts and - (void)applicationDidBecomeActive:(UIApplication *)application
after the sync is complete
