Instance Method

presentedSubitemDidChange(at:)

Tells the delegate that the contents or attributes of the specified item changed.

Declaration

optional func presentedSubitemDidChange(at url: URL)

Parameters

url

The URL of the item in the presented directory that changed. The item need not be at the top level of the presented directory but may itself be inside a nested subdirectory.

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.
