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 use NSFileManager to get the current device disk space (total, used, and free) like so... let systemAttributes = try? NSFileManager.defaultManager().attributesOfFileSystemForPath(NSHomeDirectory() as String) let space = (systemAttributes?[NSFileSystemSize] as? NSNumber)?.longLongValue Is there any way to do something similar for a user's iCloud account? I want to be able to present a user's iCloud disk space statistics within an app. 回答1: Capacity iCloud online capacity is determined by

问题 I am building an iOS app in which the user can download different files. I am using an URLSessionDownloadTask and an URLSession to download a file asynchronously. When the download is finished, the destination folder is by default, the tmp/ directory. So, when the download ends, I need to move the temporary file to another directory. For a picture or a song, this takes only 1 second maybe even less. But when the file is a video for example, it can take up to 15 seconds. The issue To allow the

问题 How do I iterate through a folder (with subdirectories that might have further subdirectories in them) and delete the file if it's not a directory? Essentially, I'm asking how to clear all the directories. I'm having a little trouble with the enumeratorAtPath: method in this regard, because I'm not sure how to ask the enumerator if the current file is a directory or not. Does require looking through the fileAttributes dictionary. Note: This may be very wrong of me, but I initialize the

Below is a screen shot of the hierarchy, I am attempting to get all the files in the 'test' folder: Any help is greatly appreciated, I have attempted to use file manager and bundle main path but to no joy so far.
