问题 I have an iOS 7 application that saves a custom object to app's iCloud Docs folder as a file.

问题 Basically I have some sort of bug with tableView, i noticed that my tableView is not always getting updated correctly, and i tried debugging it and what i noticed is that tableView class is not always getting called to update the table. What am i doing wrong ?

问题 My app uses a custom class as its data model: class Drug: NSObject, NSCoding { // Properties, methods etc... } I have just created a Today extension and need to access the user’s data from it, so I use NSCoding to persist my data in both the app container and the shared container. These are the save and load functions in the main app: func saveDrugs() { // Save to app container let isSuccessfulSave = NSKeyedArchiver.archiveRootObject(drugs, toFile: Drug.ArchiveURL.path) if isSuccessfulSave {

问题 I need some help to load and read UIColor from UserDefaults. I found a nice extension to do that: extension UserDefaults { func colorForKey(key: String) -> UIColor? { var color: UIColor? if let colorData = data(forKey: key) { color = NSKeyedUnarchiver.unarchiveObject(with: colorData) as? UIColor } return color } func setColor(color: UIColor?, forKey key: String) { var colorData: NSData? if let color = color { colorData = NSKeyedArchiver.archivedData(withRootObject: color) as NSData? } set

For a game I'm creating, I want to be able to create a lot of custom levels that can be loaded easily. Each level should have a .sks interface file and its own SKScene subclass .swift file.
