ios - 为什么按钮不起作用

Question

“开始按钮”没有正常工作。单击时应隐藏 subview 。这是 View Controller 。我尝试将最终函数放在不同的地方。

class timeViewController: UIViewController {


var score = 0
var buttonState: Int = 0;
var gameOver = UIView()

@IBAction func start(sender: AnyObject) {

  if(displayTime.text != stoptimer.text){

        var gameOver = UIView(frame: CGRectMake(0, 0, 0, 0))
        gameOver.backgroundColor = UIColor.blackColor().colorWithAlphaComponent(0.2)
        //gameOver.opaque = false
        self.view.addSubview(gameOver)
        UIView.animateWithDuration(0, animations:{
            gameOver.frame.size = CGSizeMake(667, 667)
        })

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

        func pressed(sender: UIButton!){
             gameOver.removeFromSuperview()
        }
  }
}

要删除您对此代码的“GaneOver” View 更改:

gameOver.removeFromSuperview()

我希望你在 viewDidLoad 或 viewWillAppear 之外编写“func pressed”
