Here's a NSCoding compliant object. I would like to save and recover it from the app's documents directory in Swift 3. I imagine it's a save method and recover method. How is this done? import Foundation class Book: NSObject, NSCoding { var title: String var author: String var pageCount: Int var categories: [String] var available: Bool init(title:String, author: String, pageCount:Int, categories:[String],available:Bool) { self.title = title self.author = author self.pageCount = pageCount self.categories = categories self.available = available } // MARK: NSCoding required convenience init?

I would like to get milliseconds from creation time of file attribute When I get file attribute, I use NSDateFormatter to convert file creation time (NSDate) to NSString. [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss:SS: A"]; ss --> seconds SS --> should be millisecond A --> milliseconds of the date I get 00 for SS and get 54487000 for A. I notice that the last three digits are always zero for NSDate come from file attribute of any files. But when I use the same formatter with the NSDate come from [NSDate date], the last three digits are not zero for A, and SS digit is not always zero.

I store an .jpg image i the iOS documents directory. I can write files and read files but when it comes to deleting them it says that there is no such file but that cannot be because I can read it with the same url.

String) let data = NSData(contentsOf: fullPath!) Deleting: let fileManager = FileManager.default fileManager.delegate = self let paths = NSSearchPathForDirectoriesInDomains

I saw a WWDC 2010 video about NSFileProtectionComplete and protecting app's data. Are there any examples out there? Does any one have sample code to share? See the NSFileManager class doc: The file is stored in an encrypted format on disk and cannot be read from or written to while the device is locked or booting. It's basically file vault for individual files. You just pass the constant when you set the file attributes. To mark a file as protected, you must add an extended attribute to it. The Foundation framework includes two ways to add this attribute: When writing the contents of an NSData

I want to store pictures taken from camera and video recordings from my application in a separate folder in temporary directories for a while. And as the task is being completed, they shall be going to save into the database. How do I save pictures taken from camera & video recording files in a separate folder in temp directories? You are looking for this to get tot he caches folder to store temporary files: NSString* path = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject]; From there you can use NSFileManager to create and remove the directories you
