You can set your boolean by using: [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@”logged_in”]; [[NSUserDefaults standardUserDefaults] synchronize]; and read it by using this code: if(![[NSUserDefaults standardUserDefaults] boolForKey:@”logged_in”]) { [self displayLogin]; } else { [self displayMainScreen]; }
This applies to OS 1 only. See below for better answers. I got it working using your method. I guess there’s a couple of things you can check: 1) Are you synchronising the defaults after you set the value: defaults?.synchronize(); NSLog(“%@ “, defaults?.dictionaryRepresentation()) 2) Have you enabled the App Group in both your app and … Read more
At first, NSUserDefaults is a dictionary (NSDictionary I think). Every app has its own user defaults, so you cannot access the user defaults from any other app. If the user (the one who plays your game) makes a new highscore, you have to save that highscore like this: let highscore = 1000 let userDefaults = … Read more
They are usually not reset unless the user deletes the app. For basic data, NSUserDefaults is the best way to save data such as preferences, dates, strings etc. If you are looking to save images and files, the file system is a better bet.
You need to create Data instance from your JobCategory model using JSONEncoder and store that Data instance in UserDefaults and later decode using JSONDecoder. struct JobCategory: Codable { let id: Int let name: String } // To store in UserDefaults if let encoded = try? JSONEncoder().encode(category) { UserDefaults.standard.set(encoded, forKey: UserDefaultsKeys.jobCategory.rawValue) } // Retrieve from UserDefaults … Read more
You cannot use NSUserDefaults for a custom class. From the documentation: The NSUserDefaults class provides convenience methods for accessing common types such as floats, doubles, integers, Booleans, and URLs. A default object must be a property list, that is, an instance of (or for collections a combination of instances of): NSData, NSString, NSNumber, NSDate, NSArray, … Read more
From your code I see you are storing some array // Your code NSUserDefaults.standardUserDefaults().setObject(myArray, forKey: “\(identity.text!)listA”) and retrieving a string //Your code let tabledata = NSUserDefaults.standardUserDefaults().stringForKey(“\(identity.text!)listA”) There is probably a type mismatch, You store one type and retrieve another type. While retrieving either use arrayForKey() or objectForKey() see the code below. let tabledata = NSUserDefaults.standardUserDefaults().arrayForKey(“\(identity.text!)listA”) … Read more
The approach from caram is in general ok but there are so many problems with the code that SmushyTaco did not get it work. Below you will find an “Out of the Box” working solution. 1. UserDefaults propertyWrapper import Foundation import Combine @propertyWrapper struct UserDefault<T> { let key: String let defaultValue: T init(_ key: String, … Read more
I think this is due to a bug in the iOS8 Beta Simulator. The expected behavior is that when the app is deleted, the NSUserDefaults for that app are deleted as well. However, NSUserDefaults are NOT deleted when you remove an app from the simulator. They are correctly deleted when you delete them from a … Read more
You are needlessly complicating things. Why are you converting the date to a time interval (then the time interval to a different primitive)? Just [sharedDefaults setObject:theDate forKey:@”theDateKey”] and be done with it. NSDate is one of the “main types” supported by the PLIST format (dates, numbers, strings, data, dictionaries, and arrays), so you can just … Read more
