Method Detail

didEnumerateItems

void didEnumerateItems(NSArray<?> updatedItems)

finishEnumeratingUpToPage

void finishEnumeratingUpToPage(NSData nextPage)

Call this method after enumerating a full page of items. If you set a non-nil nextPage, -[NSFileProviderEnumerator enumerateItemsToObserver:startingAtPage:] might be called with nextPage to enumerate more items. This is typically driven by the user scrolling a UIDocumentBrowserViewController presenting a directory containing more child items that would fit in the view.

Page data is limited to 500 bytes. Setting a larger nextPage interrupts the enumeration.

finishEnumeratingWithError

void finishEnumeratingWithError(NSError error)
