我在.enabled按鈕快速代碼方面遇到麻煩

Question

我在玩迷你瑣事游戲時，一切正常。 現在唯一的問題是，當用戶完成回答問題時，按鈕仍處於啟用狀態。

我創建了一個禁用和啟用buttons功能，而禁用buttons功能正在UIButton動作中工作，但在這種情況下無法正常工作，我不知道我是否錯過了某些東西或Im做錯了什么。

PS：我在快速代碼中很新，這就是我所擁有的：

 private func pickingRandomQuestion() {
    if questions.count > 0  {
        questionNumber = random() % questions.count
        questionLabel.text = questions[questionNumber].Question 
        answerNumber = questions[questionNumber].Answer
        imgDisplay.image = questions[questionNumber].Img

        answerA.setTitle(questions[questionNumber].Answers[0], forState: .Normal)
        answerB.setTitle(questions[questionNumber].Answers[1], forState: .Normal)
        answerC.setTitle(questions[questionNumber].Answers[2], forState: .Normal)
        answerD.setTitle(questions[questionNumber].Answers[3], forState: .Normal)

        questions.removeAtIndex(questionNumber)
    } else {

        finishGame.hidden = false
        disableButtons()
        //Here is my problem 
        //NSLog("Done")
        //NSLog(String(finalScore))


    }
}

@IBAction func btnA(sender: UIButton) {
    unhide()
    disableButtons()
    if answerNumber == 1 {
        endLabel.text = "You are Right"
        finalScore+=1
    } else {
        endLabel.text = "You are Wrong"
    }
}
@IBAction func btnB(sender: UIButton) {
    unhide()
    disableButtons()
    if answerNumber == 2 {
        endLabel.text = "You got it"
        finalScore+=1
    } else {
        endLabel.text = "You are Wrong"
    }
}
@IBAction func btnC(sender: UIButton) {
    unhide()
    disableButtons()
    if answerNumber == 3 {
        endLabel.text = "You are Correct"
        finalScore+=1
    } else {
        endLabel.text = "You are Wrong"
    }
}
@IBAction func btnD(sender: UIButton) {
    unhide()
    disableButtons()
    if answerNumber == 4 {
        endLabel.text = "You are Right"
        finalScore+=1
    } else {
        endLabel.text = "You are Wrong"
    }
}
 @IBAction func nextQuestion(sender: UIButton) {
    pickingRandomQuestion()
    hide()
    enableButtons()
}

Answer 1

answerA.enabled = false

您的問題禁用功能不起作用嗎？
