iOS开发数独小游戏实例
本文实例为大家分享了iOS实现数独小游戏的具体代码,供大家参考,具体内容如下
一、界面设计
如下图。图1是用户打开程序后的主页面,点击“开始游戏”后进入游戏页面(图2,图3)。游戏界面上方是显示条,显示玩家当前选中的按钮。当玩家想要在九宫格中填入数字时,只需点击下方1-9的数字控件,显示条上会自动显示玩家当前选中的数字编号,再点击玩家想要填入的位置,就可以填入控件了。
最下方三个按钮分别是“提交”“橡皮擦”“标记”控件。当玩家点击“提交”按钮,系统会自动为玩家结算游戏分数;当玩家点击“橡皮擦”时,可以擦除九宫格上指定位置的数字;当玩家点击“标记”时,可以为九宫格上的格子添加一个小红旗作为标记。游戏界面上方有一个导航条,点击house图标会回到主页面。
二、实现
1. 先搭入口界面,包括一个image view和button,添加一个ViewController作为游戏界面,在入口界面和游戏界面之间添加segue,当点击“开始游戏”时跳转到游戏界面。
2.为游戏界面添加必要的控件,用9x9个button实现九宫格,添加9个数字按钮和3个功能控件,为了便于用户使用,需要添加一个显示条。通过用户按下button得知玩家想要在九宫上填入数字的位置坐标,button通过Tag识别。
3.关联代码。将九宫格,9个数字按钮,以及3个功能控件与代码关联,同时新建一个Board类,Board类包含九宫格游戏进度和答案计算等。
// // ViewController.swift // import UIKit class ViewController: UIViewController { var inputNumber: String = " " var board = Board() var oldx: Int = 0 var oldy: Int = 0 var oldValue: Int = 0 @IBOutlet weak var display: UILabel! @IBAction func inNumber(_ sender: UIButton) { if let num = sender.currentTitle{ switch num { case "" :inputNumber = "" ;display.text = "" case "1" :inputNumber = "1" ;display.text = "1" case "2" :inputNumber = "2" ;display.text = "2" case "3" :inputNumber = "3" ;display.text = "3" case "4" :inputNumber = "4" ;display.text = "4" case "5" :inputNumber = "5" ;display.text = "5" case "6" :inputNumber = "6" ;display.text = "6" case "7" :inputNumber = "7" ;display.text = "7" case "8" :inputNumber = "8" ;display.text = "8" case "9" :inputNumber = "9" ;display.text = "9" default: break } } } @IBAction func setNumber(_ sender: UIButton) { let pushTag: Int = sender.tag let hightTag: Int = pushTag / 10 let lowTag: Int = pushTag % 10 if board.question[hightTag - 1][lowTag - 1] == 0 { sender.setTitle(inputNumber, for: UIControl.State.normal) board.change(x: hightTag - 1, y: lowTag - 1, value: Int(inputNumber) ?? 0) oldx = hightTag - 1 oldy = lowTag - 1 oldValue = Int(inputNumber) ?? 0 } } @IBAction func eraser(_ sender: UIButton) { inputNumber = " " display.text = "橡皮擦" } @IBAction func finish(_ sender: UIButton) { if board.check() { display.text = "You Win!" } else { display.text = "Score: \(board.score)" } } @IBAction func backHome(_ sender: UIBarButtonItem) { dismiss(animated: true, completion: nil) } override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. display.text = "begin" } }
// // Board.swift // import UIKit class Board{ var score: Int = 0 var question: [[Int]] = [[0,0,0,1,8,0,9,3,0], [1,8,6,0,0,0,0,0,7], [0,5,0,7,4,0,0,0,0], [5,0,4,0,0,0,3,0,6], [0,0,0,3,9,4,0,0,2], [2,3,0,0,0,0,0,1,0], [0,0,9,0,0,3,0,0,8], [0,0,2,9,0,5,7,0,0], [0,7,0,0,0,8,0,9,0],] var nowBoard: [[Int]] = [[0,0,0,1,8,0,9,3,0], [1,8,6,0,0,0,0,0,7], [0,5,0,7,4,0,0,0,0], [5,0,4,0,0,0,3,0,6], [0,0,0,3,9,4,0,0,2], [2,3,0,0,0,0,0,1,0], [0,0,9,0,0,3,0,0,8], [0,0,2,9,0,5,7,0,0], [0,7,0,0,0,8,0,9,0],] var answer: [[Int]] = [[4,2,7,1,8,6,9,3,5], [1,8,6,5,3,9,2,4,7], [9,5,3,7,4,2,6,8,1], [5,9,4,8,2,1,3,7,6], [7,6,1,3,9,4,8,5,2], [2,3,8,6,5,7,4,1,9], [6,1,9,4,7,3,5,2,8], [8,4,2,9,1,5,7,6,3], [3,7,5,2,6,8,1,9,4],] func getNum(x: Int, y: Int) -> Int { return nowBoard[x][y] } func change(x: Int, y: Int, value: Int) { nowBoard[x][y] = value } func check() -> Bool { var countCorrect: Float = 0 var countEmpty: Float = 0 for i in 0...8{ for j in 0...8 { if nowBoard[i][j] == answer[i][j] { countCorrect += 1 } if question[i][j] == 0 { countEmpty += 1 } } } //score = Int(((countQues - countCorrect) / countQues) * 100) score = Int( ((countCorrect + countEmpty - 81) / countEmpty) * 100 ) if nowBoard == answer { score = 100 return true } else { return false } } }
三、试运行(附GIF)
四、评价
优点:程序简单,代码量小,无复杂算法。
缺点:游戏盘面相对固定,未实现数独盘面的随机生成、自动生成数独的解、以及不同难度生成。
