Loading And Continuing To Add Integers Xcode Swift - ios

Question

I am able to save an integer and load it using NSUserdeafaults but when I load up the number and try to continue adding to that number it starts at 0.
Example: I press the button 7 times and switch to a different page. I go back and click load button and it days 7. When I click it again it says 1.
Here is my "press for money" code:
//Press for Money
#IBAction func MoneyPress(sender: AnyObject) {
Money += 1
var MoneyNumberString:String = String(format: "Dollars:%i", Money)
self.DollarsLabel.text = (string: MoneyNumberString)
let defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
defaults.setObject(MoneyNumberString, forKey: "money")
defaults.synchronize()
}
Loading Code:
#IBAction func LoadTestButton(sender: UIButton) {
let defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
var money = defaults.valueForKey("money") as? String
DollarsLabel.text! = money!
}
Please help if you know how to make it continue adding to that number.
Full Code:
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var MoneyButton: UIButton!
#IBOutlet weak var OptionButton: UIButton!
#IBOutlet weak var FeelingLuckyButton: UIButton!
#IBOutlet weak var TrophiesButton: UIButton!
#IBOutlet weak var DollarsLabel: UILabel!
#IBOutlet weak var BuyNowOne: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
var Money = Int(0)
//Press for Money
#IBAction func MoneyPress(sender: AnyObject) {
Money += 1
var MoneyNumberString:String = String(format: "Dollars:%i", Money)
self.DollarsLabel.text = (string: MoneyNumberString)
let defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
defaults.setObject(MoneyNumberString, forKey: "money")
defaults.synchronize()
}
#IBAction func LoadTestButton(sender: UIButton) {
let defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
var money = defaults.valueForKey("money") as? String
DollarsLabel.text! = money!
}
}

The problem is that you're setting Money to 0 when you actually want to set it to contain the value in your NSUserDefaults. To do that in your LoadTestButton method, try this:
#IBAction func LoadTestButton(sender: UIButton) {
let defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
var money = defaults.valueForKey("money") as? String
DollarsLabel.text! = money!
// Set "Money" to contain the numbers in your "money"
// string converted to an Int
Money = money!.stringByTrimmingCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet).toInt()!
}
