问题 I'm loading a lot of image paths into a NSURL. The images are in a folder ordered from 1.PNG, 2.PNG, 3.PNG to 1500.PNG. When I trie to load them: let imagePath = path + "/images" let url = NSURL(fileURLWithPath: imagePath) print(url) let fileManager = NSFileManager.defaultManager() let properties = [NSURLLocalizedLabelKey, NSURLCreationDateKey, NSURLLocalizedTypeDescriptionKey] do { imageURLs = try fileManager.contentsOfDirectoryAtURL(url, includingPropertiesForKeys: properties, options

问题 I want to get a thumbnail representation of a file I have to display in my app. I'm using NSURL here: NSDictionary *thumbnails = nil; BOOL success = [fileURL getResourceValue:&thumbnails forKey:NSURLThumbnailDictionaryKey error: &error]; This works fine if I am connected to iCloud, and the URL is a link to a file stored in iCloud. The fileURL is something like: file:///Users/me/Library/Mobile%20Documents/BJXXGLR9R3~com~myapp~icloud/FileStorage/contact-page%20copy.png If I use the same code

问题 I login to my server using a SOAP web service . Once logged in, many of the files that I am viewing are only available to the logged in user, so iOS must create a session in NSURL or something. When trying to preview a video file using MPMoviePlayerViewController it will not work, it just loads up the viewController, then dismisses it. If I use QuickLook it does work, probably because I download the video locally first, then view it. But, I don't want to do it this way, I want to stream the

问题 I'd like to use -[NSURL parameterString] to parse out the parameters of a URL I've been passed. It says URL must conform to RFC 1808 but now wondering if ours do?!? We use something like: http://server/path/query?property1=value1&property2=value2 but RFC 1808 never mentions the ampersand ( & ) as a valid parameter separator (at least the way I read it). It suggests the semicolon ( ; ). Perhaps because it was drafted in 1995? Has the & replaced the ; ? If so anyone verify if NSURL's

问题 I'm following a basic tutorial on building a simple iOS app in Swift. It is written in Swift 2.x, and I work with XCode 8 Beta and Swift 3. The tutorial suggests using NSFileManager to find a data directory. Class names have changed, so the auto-fixed Swift 3 looks like this: static let DocumentsDirectory = FileManager().urlsForDirectory(.documentDirectory, inDomains:.userDomainMask).first! static let ArchiveURL = DocumentsDirectory.URLByAppendingPathComponent("meals") However, Xcode now
