import UIKit

class ViewController: UIViewController {
    let ballArray = [#imageLiteral(resourceName: "ball1.png"),#imageLiteral(resourceName: "ball2.png"),#imageLiteral(resourceName: "ball3.png"),#imageLiteral(resourceName: "ball4.png"),#imageLiteral(resourceName: "ball5.png")] //[圖1,圖2,圖3,圖4,圖5]
    
    @IBOutlet weak var imageView: UIImageView! //拉Storyboard圖到code來
    
    @IBAction func askButtonPressed(_ sender: UIButton) { //拉Storyboard按鈕到code來

        imageView.image = ballArray[Int.random(in: 0...4)] //圖=陣列其中一元素
    }
    
}
