Ios 加载并继续添加整数Xcode Swift

我可以保存一个整数并使用NSUserdeafaults加载它，但当我加载该数字并尝试继续添加该数字时，它从0开始

示例：我按下按钮7次，然后切换到另一页。我返回并单击“加载”按钮，它将在第7天加载。当我再次单击它时，它会显示1

这是我的货币代码：

//要钱

@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()

}

加载代码：

@IBAction func LoadTestButton(sender: UIButton) {
        let defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
        var money = defaults.valueForKey("money") as? String
        DollarsLabel.text! = money!
}

如果您知道如何使其继续增加该数字，请提供帮助

完整代码：

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!
}

}

问题是，当您实际希望将货币设置为包含NSUserDefaults中的值时，您将货币设置为0。要在LoadTestButton方法中执行此操作，请尝试以下操作：

@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()!
}

您最初在哪里设置货币变量？这是一个整数，用于计算点击次数。是的，但您第一次设置它是什么时候？我假设您希望它等于存储在NSUserDefaults中的值…您可以发布该代码吗？我在上面发布了完整的代码，它告诉我要放置！最后，当我把它放进去时，它告诉我再放一个，然后它告诉我删除那个，依此类推。我该怎么解决这个问题？你可能把它！在错误的地方。一秒钟。。。我会更新的。
