#7 Light App

這支是用touchesBegan去寫的，當營幕被touch了一下，uiView就會變顏色

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?)

程式碼如下：

@IBOutlet weak var changeView: UIView!
var number = 0
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
number = number + 1
switch number % 7 {
case 0:
changeView.backgroundColor = UIColor.red
case 1:
changeView.backgroundColor = UIColor.orange
case 2:
changeView.backgroundColor = UIColor.yellow
case 3:
changeView.backgroundColor = UIColor.green
case 4:
changeView.backgroundColor = UIColor.blue
case 5:
changeView.backgroundColor = UIColor.purple
case 6:
changeView.backgroundColor = UIColor.brown
default:
changeView.backgroundColor = UIColor.black
break
}
}
