问题 The problem What I have so far is code that creates a new local file and deletes the iCloud file. Is it possible to rename an iCloud document, so that it stays in iCloud? GarageBand can do it. It's possible to rename an iCloud song. After the rename is done, the song is still in iCloud. However GarageBand is an Apple app, so it may use private apis. My current code: - (void)moveFrom:(NSURL*)sourceURL moveTo:(NSString*)destinationName completion:(void (^)())completion { MyDocument *document =

问题 I have an iOS app that is trying to read files from an external storage device without importing them into the App's sandbox. I have followed Apple's documentations outlined here to do this -- Providing Access to Directories I'm able to retrieve the selected directory ( which is on an external storage device connected via the Lightning port ) and enumerate the files inside the directory. However, when I try to do something with those files as per the recommended pattern, I get a failure and

问题 I'm trying to write a simple (toy) program that uses the NSFilePresenter and NSFileCoordinator methods to watch a file for changes. The program consists of a text view that loads a (hardcoded) text file and a button that will save the file with any changes. The idea is that I have two instances running and saving in one instance will cause the other instance to reload the changed file. Loading and saving the file works fine but the NSFilePresenter methods are never called. It is all based
