After an iPhone app is put into background, then the user clicks on it again and it comes back to foreground, THEN

Question – How to tell what is the current UIView/UIController after an iPhone app in brought back to foreground?

I know that the application delegate’s applicationDidBecomeActive method can be used to trap the return to foreground. I also know that each controller could subscribe via notification centre to UIApplicationDidBecomeActiveNotification.

But if what I want to do is reload the UI data in the UIView/UIController that is displayed, and not carry out this same operation through all other view/controllers, how can I tell which is the one to do the reloadData on?
