网站死链接扫描人才招聘网站开发+源代码

1.创建新项目Dice

 2.图标

 删去AppIcon，将解压后的AppIcon.appiconset文件拖入Assets包。

 3.将素材点数1-6通过网页制作成2x，3x版本并拖入Asset。

 4.设置对应的UI。

 5.拖入Button组件并设置style。

 6.Ctrl加拖拽将Button拖拽到ViewController里，并设置Connection，Name等，并点击Connect。

 同样方式创建两个骰子的代码。

import UIKitclass ViewController: UIViewController {@IBOutlet weak var diceImageView1: UIImageView!@IBOutlet weak var diceImageView2: UIImageView!@IBAction func roll(_ sender: Any) {}override func viewDidLoad() {super.viewDidLoad()// Do any additional setup after loading the view, typically from a nib.}override func didReceiveMemoryWarning() {super.didReceiveMemoryWarning()// Dispose of any resources that can be recreated.}
}

 7.继续编写代码创造随机数。

import UIKitclass ViewController: UIViewController {@IBOutlet weak var diceImageView1: UIImageView!@IBOutlet weak var diceImageView2: UIImageView!@IBAction func roll(_ sender: Any) {var index1: Int = Int.random(in: 1...6)var index2: Int = Int.random(in: 1...6)diceImageView1.image = UIImage(named: "dice\(index1)")diceImageView2.image = UIImage(named: "dice\(index2)")    }override func viewDidLoad() {super.viewDidLoad()// Do any additional setup after loading the view, typically from a nib.}override func didReceiveMemoryWarning() {super.didReceiveMemoryWarning()// Dispose of any resources that can be recreated.}}

8.启动运行

9.程序加载时就随机扔骰子

import UIKitclass ViewController: UIViewController {let diceArr = ["dice1", "dice2", "dice3", "dice4", "dice5", "dice6"]@IBOutlet weak var diceImageView1: UIImageView!@IBOutlet weak var diceImageView2: UIImageView!@IBAction func roll(_ sender: Any) {//调用摇骰子函数updateDiceImages()}//当程序加载的时候的活动override func viewDidLoad() {super.viewDidLoad()// Do any additional setup after loading the view, typically from a nib.//调用摇骰子函数updateDiceImages()}override func didReceiveMemoryWarning() {super.didReceiveMemoryWarning()// Dispose of any resources that can be recreated.}func updateDiceImages(){var index1: Int = Int.random(in: 0...5)var index2: Int = Int.random(in: 0...5)diceImageView1.image = UIImage(named: diceArr[index1])diceImageView2.image = UIImage(named: diceArr[index2])    }}

10.当用户摇晃骰子后调用摇骰子函数。

import UIKitclass ViewController: UIViewController {let diceArr = ["dice1", "dice2", "dice3", "dice4", "dice5", "dice6"]@IBOutlet weak var diceImageView1: UIImageView!@IBOutlet weak var diceImageView2: UIImageView!@IBAction func roll(_ sender: Any) {//调用摇骰子函数updateDiceImages()}//当程序加载的时候的活动override func viewDidLoad() {super.viewDidLoad()// Do any additional setup after loading the view, typically from a nib.//调用摇骰子函数updateDiceImages()}override func didReceiveMemoryWarning() {super.didReceiveMemoryWarning()// Dispose of any resources that can be recreated.}func updateDiceImages(){var index1: Int = Int.random(in: 0...5)var index2: Int = Int.random(in: 0...5)diceImageView1.image = UIImage(named: diceArr[index1])diceImageView2.image = UIImage(named: diceArr[index2])    }//当用户摇晃手机时触发摇骰子override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {updateDiceImages()}}
