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。
