NSUserDefaults Not Saving TextField Text (Swift)

Question

I\'m trying to create a game with Swift, and I want to add the ability to create a username, which will be saved in NSUserDefaults. This is my code:

println(&         


        

Answer 1

I made a small modification to Roman's answer with Swift 2.0 and Xcode 6.4.

saving:

    var myValue:NSString = usernameTF.text

    NSUserDefaults.standardUserDefaults().setObject(myValue, forKey:"Username")
    NSUserDefaults.standardUserDefaults().synchronize()

retrieving:

var myOutput = NSUserDefaults.standardUserDefaults().objectForKey("Username")
if (myOutput != nil)
{
    self.title = "Welcome "+((myOutput) as! String)
    }

Answer 2

In Swift 4.1

 UserDefaults.standard.set(textfield.text, forKey: "yourKey") // saves text field text
  UserDefaults.standard.synchronize()

// To Retrieve
textfield.text = UserDefaults.standard.value(forKey:"yourKey") as? String

Answer 3

println("Textfield Text: \(usernameTextfield.text)")

var myValue:NSString = usernameTextfield.text

NSUserDefaults.standardUserDefaults().setObject(myValue, forKey:"Username")
NSUserDefaults.standardUserDefaults().synchronize()

var myOutput: AnyObject? = NSUserDefaults.standardUserDefaults().objectForKey("Username")
println(myOutput)

Answer 4

In Swift 3.0

    let userDefult = UserDefaults.standard //returns shared defaults object.

    if let userName = usernameTextfield.text {
        //storing string in UserDefaults
        userDefult.set(userName, forKey: "userName") //Sets the value of the specified default key in the standard application domain.
    }

    print(userDefult.string(forKey: "userName")!)//Returns the string associated with the specified key.

For swift 3.0, You can create user default by,

UserDefaults.standard.set("yourValue", forKey: "YourString")

To Print the value in console :

print(UserDefaults.standard.string(forKey: "YourString")!)
