为什么我不能用gestureTapRecogniser调用我的函数 [英] Why can't I call my function with gestureTapRecogniser

问题描述

我有这个简单的功能，当有人点击屏幕时，函数内部的代码会执行，我知道函数中的代码可以工作，输入时我没有错误。

I have this simple function that when someone taps the screen, the code inside the function executes, I know the code in the function works and I get no error when it is typed.

    func reload(gestureRecognizer: UITapGestureRecognizer) {
        let skView = self.view!
        skView.presentScene(scene)
    }

我有这个if语句，并且所有代码都工作，除非我在某个事件发生后运行该函数。在我尝试调用'reload（）'的行中，我收到错误'使用未解析的标识符重新加载'。你能告诉我我做错了吗？谢谢！

I have this if statement, and all the code work except for when I ry to run the function after a certain event has occurred. In the line where I try and call 'reload()' I get the error 'Use of unresolved identifier reload'. Can you please tell me what I've done wrong. Thanks!

    if score[0] >= 10 {
        pauseGame()

        let textLabel = SKLabelNode(fontNamed: "Helvetica")
        textLabel.fontSize = 30
        textLabel.fontColor = SKColor.white
        textLabel.position = CGPoint(x:  20, y: 20)
        textLabel.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center
        textLabel.text = "HELLO"
        addChild(textLabel)

        reload()

    }
    else if
        score [1] >= 10 {
        pauseGame()
        sleep(5)

        let textLabel = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
        textLabel.fontSize = 30
        textLabel.fontColor = SKColor.white
        textLabel.position = CGPoint(x:  20, y: 20)
        textLabel.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center
        textLabel.text = "HELLO"
        addChild(textLabel)

        reload()

    }

推荐答案

只需更改

reload()

到

reload(gestureRecognizer: nil)

和重新加载方法参数应为 UITapGestureRecognizer？可选。

func reload(gestureRecognizer: UITapGestureRecognizer?) {
        let skView = self.view!
        skView.presentScene(scene)
}

另一个简短的方法

更改使用 UITapGestureRecognizer

...action: #selector(self.reload())...

表示删除（_：）无需更多操作只需调用 reload（）功能。

means remove (_:) no need to do anythings more just call reload() function.
