是否可以为功能分配开关？

Question

我有一个按钮来控制计时器。我轻松，有规律，有困难。我在一个按钮内创建了三个开关。如何将每个按钮分配给特定开关？像func hard $将分配给switch（buttonStatehard）。

 var buttonStatehard: UISwitch!

@IBAction func start(sender: AnyObject) {

    //stop within 5 ms
    buttonStatehard.setOn(false, animated: true)
    switch(buttonStatehard){
    case 0:
        let aSelector : Selector = "updateTime"
        timer = NSTimer.scheduledTimerWithTimeInterval(0.01, target: self, selector: aSelector, userInfo: nil, repeats: true)
        startTime = NSDate.timeIntervalSinceReferenceDate()
        //buttonStatehard = 1;

        break;

    case 1:
        timer.invalidate()
            if(displayTime.text == stoptimer.text){
            score++
            scoring.text = String(score)
            try = 0
            attempt.text = String(try)

        }

        if(displayTime.text != stoptimer.text){
            try++
            attempt.text = String(try)
            if(try > 2){
                gameOver = UIView(frame: CGRectMake(0, 0, 0, 0))
                gameOver.backgroundColor = UIColor.blackColor().colorWithAlphaComponent(0.6)
                gameOver.opaque = false
                self.view.addSubview(gameOver)
                //UIView.animateWithDuration(0, animations:{
                self.gameOver.frame.size = CGSizeMake(1000, 1000)

                //})

                gobutton = UIButton()
                let image = "button.png"
                gobutton.setImage(UIImage(named: image), forState: .Normal)
                gobutton.frame = CGRectMake(135, 300, 95, 95)
                gobutton.setTranslatesAutoresizingMaskIntoConstraints(false)
                gobutton.addTarget(self, action: "pressed:" , forControlEvents: UIControlEvents.TouchUpInside)
                self.view.addSubview(gobutton)

                self.view.addConstraint(horizontalConstraint1)

                let verticalConstraint2 = NSLayoutConstraint(item: gobutton, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: self.view, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0)
                self.view.addConstraint(verticalConstraint2)

如何将每个按钮分配给特定开关？

func ez$ (sender: UIButton!){

}

func reg$ (sender: UIButton!){

}

func hard$ (sender: UIButton!){
    buttonStatehard.setOn(true, animated:true)

    //error EXC_BAD_INSTRUCTION
}

我为你找到了这个，如果它不是你想要的，请评论。

@IBAction func buttonClicked(sender: UIButton) {
    if mySwitch.on {
        myTextField.text = "The Switch is Off"
        println("Switch is on")
        mySwitch.setOn(false, animated:true)
    } else {
          myTextField.text = "The Switch is On"
          mySwitch.setOn(true, animated:true)
    }
}
