一、界面設計

如下圖，圖1是用戶打開程式后的主頁面，點擊“開始游戲”后進入游戲頁面（圖2,圖3），游戲界面上方是顯示條，顯示玩家當前選中的按鈕，當玩家想要在九宮格中填入數字時，只需點擊下方1-9的數字控制元件，顯示條上會自動顯示玩家當前選中的數字編號，再點擊玩家想要填入的位置，就可以填入控制元件了，

最下方三個按鈕分別是“提交”“橡皮擦”“標記”控制元件，當玩家點擊“提交”按鈕，系統會自動為玩家結算游戲分數；當玩家點擊“橡皮擦”時，可以擦除九宮格上指定位置的數字；當玩家點擊“標記”時，可以為九宮格上的格子添加一個小紅旗作為標記，游戲界面上方有一個導航條，點擊house圖示會回到主頁面，

二、實作

1. 先搭入口界面，包括一個image view和button，添加一個ViewController作為游戲界面，在入口界面和游戲界面之間添加segue，當點擊“開始游戲”時跳轉到游戲界面，

2.為游戲界面添加必要的控制元件，用9x9個button實作九宮格，添加9個數字按鈕和3個功能控制元件，為了便于用戶使用，需要添加一個顯示條，通過用戶按下button得知玩家想要在九宮上填入數字的位置坐標，button通過Tag識別，

3.關聯代碼，將九宮格，9個數字按鈕，以及3個功能控制元件與代碼關聯，同時新建一個Board類，Board類包含九宮格游戲進度和答案計算等，

四、評價

優點：程式簡單，代碼量小，無復雜演算法，

缺點：游戲盤面相對固定，未實作數獨盤面的隨機生成、自動生成數獨的解、以及不同難度生成，
