Change NSUserDefaults bool value

I want to change the character of my game when the user touches the character, so I used a NSUserDefault to store a bool and check if the user pressed on the button that will change the character.

if userDefaults.boolForKey("PBChange") == true { hero.texture = SKTexture(imageNamed: "PoolBall") hero.size = CGSize(width: 60, height: 60) }

But somehow I need to change the "PBChange" to false after changing the character.

I wanted to do this like this: userDefaults.boolForKey("PBChange").boolValue = false

But it shows me an error that I can't do that.

How can I do this??

PLEASE HELP!!

Hey Andrés Leal,

Why don't you just store a key value pair using a String for the key and a Bool for the value.

        NSUserDefaults.standardUserDefaults().setObject(false, forKey: "yourKey")

        // Then when you retrieve the object, type cast it as a bool
        NSUserDefaults.standardUserDefaults().objectForKey("yourKey") as? Bool

       // If you want to change the value, just set a new object for that key
       NSUserDefaults.standardUserDefaults().setObject(true, forKey: "yourKey")

Good Luck

To change it, does it has to be with the same key?

Yep, when you set a newObject using an existing key - you replace the value for that key.
