從視圖控制器訪問變量覆蓋函數

Question

我正在製作一個應用程序，每次我搖動我的手機時都會從我的陣列中選擇一個隨機問題。如下所示;我試圖在「覆蓋函數motionBegan」中調用「print」函數，但它不起作用。任何人都可以幫忙。？

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; 

    }

您可以使用下面的代碼開始打印隨機值。運動開始時，您需要獲取隨機值。此外，您需要將打印功能從viewDidLoad中移出，以便每次都可以調用它。

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() 
}
