ios - 快速保存变量

Question

我需要帮助保存一个变量……两个变量。 这是我的 viewcontroller 文件。我试过 NSUser 但人们说它只应该用于设置用户数据等。任何帮助都很好 :) 谢谢

import UIKit
var wreath = 0
var box = 0




class ViewController: UIViewController {
@IBOutlet weak var YouHaveB: UILabel!
@IBOutlet weak var YouHaveW: UILabel!

@IBAction func Wreaths(sender: AnyObject) {
    wreath += 1
    YouHaveW.text = "You Have \(wreath) Wreaths"

}
@IBAction func Boxes(sender: AnyObject) {
    box += 1
    YouHaveB.text = "You Have \(box) Boxes"
}


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.
}
}

设置:

let defaults = NSUserDefaults.standardUserDefaults()
defaults.setInteger(wreath, forKey: "wreath")
defaults.setInteger(box, forKey: "box")

获取:

let defaults = NSUserDefaults.standardUserDefaults()
if let wreath = defaults. integerForKey("wreath")
{
   // do something with wreath value here
}

if let box = defaults. integerForKey("box")
{
   // do something with box value here
}
