Discussion
This method is relevant for applications that present directories. This might occur if the delegate manages the contents of a directory or manages a file that is implemented as a file package. Your implementation of this method should take whatever actions necessary to handle the change in content or attributes of the specified item.
If the presented directory is a file package, the system calls the presentedItemDidChange() method if your delegate does not implement this method.
