如何将高分保存到标签中？

Question

由于某些原因，如果我的分数大于highScore，则它不执行我的功能。 任何帮助深表感谢。

这是我的代码：

import UIKit
import AVFoundation
struct Question {
    var Question : String!
    var Answers : [String]!
    var Answer : Int!

}

class ViewController: UIViewController {

    @IBOutlet weak var highScoreLbl: UILabel!
    @IBOutlet var Buttons: [UIButton]!
    @IBOutlet weak var QLabel: UILabel!
    @IBOutlet weak var Label: UILabel!
    @IBOutlet weak var incorrectLabel: UILabel!
    @IBOutlet weak var timerLabel: UILabel!
    @IBOutlet weak var theEnd: UILabel!
    @IBOutlet weak var continueButton: UIButton!

    var scoreLbl = UILabel()

    var score = Int()

    var Questions = [Question]()

    var QNumber = Int()

    var AnswerNumber = Int()

    var wrongAnswers = Int()

    var highScore = 0

    override func viewDidLoad() {
        super.viewDidLoad()

Answer 1

highScore == score应为highScore = score ，否则highScore始终为0

看起来saveHighScore永远也不会被调用

 func PickQuestions(){

    score++
    saveHighScore()   <--- need to do things like this when score is updated
    scoreLbl.text = "\(score)"

保存：

//How to save result, do this after the highscore is set 
let defaults = NSUserDefaults.standardUserDefaults()
defaults["highScore"] = highScore

//How to read saved result, do this in your viewdidload
let defaults = NSUserDefaults.standardUserDefaults()
if let hs = defaults["highScore"] 
{
    highScore = hs
}

现在您可能必须强制转换为正确的类型才能使其正常工作，但是上面概述了基本概念
