Question

我正在创建一个应用程序，每次摇动手机时都会从我的阵列中选择一个随机问题。如下所示;我试着打电话给＆＃34;打印＆＃34;功能在＆＃34;覆盖功能motionBegan＆＃34;但它没有用。任何人都可以帮忙。？

override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        let array  = ["what did your eat for breakfast?", "First time you kissed a boy/girl? Explain.", "Whats your body count?", "When was the last time you went to church?", "Would you date someone from another religion?", "East booty(Guy) ?or let a guy eat your booty(Girl)?", "If you die right now where will you end?", "whats on your mind?", "Ever has a one night stand?", "Do you find the other person attractive?", "How old where you when you first hd sex?. Explain.", "You believe in Jesus?", "Where do you see yourself in 10 years?", "First time you gave head?", "Slap your mum or your dad? Choose one.", "Last time you watched porn?", "How much is in your account?", "One thing you hate about the other person?", "One thing you love about the other person?", "Would you kiss the person close to you?", "One thing you hate about yourself?", " One thing you love about yourself?","Suck toes or eat booty?", "Best rapper?", "Best singer?", "If you had a billion dollars for 24 hours how will you spend it?"]

            let randomIndex = Int(arc4random_uniform(UInt32(array.count)))
            // Get a random item
            let  randomItem = array[randomIndex]

        func print() {
            textField.text = randomItem
        }
    }

    override func motionBegan(_ motion: UIEventSubtype, with event: UIEvent?) {
        print;

    }

您可以使用以下代码开始打印随机值。运动开始时需要获取随机值。您还需要将view功能从viewDidLoad中取出，以便每次都可以调用它。

let array  = ["what did your eat for breakfast?", "First time you kissed a boy/girl? Explain.", "Whats your body count?", "When was the last time you went to church?", "Would you date someone from another religion?", "East booty(Guy) ?or let a guy eat your booty(Girl)?", "If you die right now where will you end?", "whats on your mind?", "Ever has a one night stand?", "Do you find the other person attractive?", "How old where you when you first hd sex?. Explain.", "You believe in Jesus?", "Where do you see yourself in 10 years?", "First time you gave head?", "Slap your mum or your dad? Choose one.", "Last time you watched porn?", "How much is in your account?", "One thing you hate about the other person?", "One thing you love about the other person?", "Would you kiss the person close to you?", "One thing you hate about yourself?", " One thing you love about yourself?","Suck toes or eat booty?", "Best rapper?", "Best singer?", "If you had a billion dollars for 24 hours how will you spend it?"]
var randomItem = ""

override func viewDidLoad() {
    super.viewDidLoad()
}

func printing() {
    let randomIndex = Int(arc4random_uniform(UInt32(array.count)))
    randomItem = array[randomIndex]         
    textField.text = randomItem
}

override func motionBegan(_ motion: UIEventSubtype, with event: UIEvent?) {
    self.printing() 
}

从视图控制器访问变量到覆盖函数
