Q: 

ViewDidLoad after ViewDidUnload is called.

Hi, I know that ViewDidUnload may be called if there is a problem in an app such as a memory warning. When that view is loaded later, ViewDidLoad is called again. If ViewDidUnload is not called, but a view that was previously shown is moved aside (like in a UINavigationBar), is ViewDidLoad called again? What can be done if one does not want the default information to be put back in?

Thanks.
