這篇文章主要為大家詳細(xì)介紹了iOS開發(fā)數(shù)獨(dú)小游戲?qū)嵗闹惺纠a介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了iOS實(shí)現(xiàn)數(shù)獨(dú)小游戲的具體代碼，供大家參考，具體內(nèi)容如下

一、界面設(shè)計(jì)

如下圖。圖1是用戶打開程序后的主頁面，點(diǎn)擊“開始游戲”后進(jìn)入游戲頁面（圖2,圖3）。游戲界面上方是顯示條，顯示玩家當(dāng)前選中的按鈕。當(dāng)玩家想要在九宮格中填入數(shù)字時(shí)，只需點(diǎn)擊下方1-9的數(shù)字控件，顯示條上會(huì)自動(dòng)顯示玩家當(dāng)前選中的數(shù)字編號，再點(diǎn)擊玩家想要填入的位置，就可以填入控件了。

最下方三個(gè)按鈕分別是“提交”“橡皮擦”“標(biāo)記”控件。當(dāng)玩家點(diǎn)擊“提交”按鈕，系統(tǒng)會(huì)自動(dòng)為玩家結(jié)算游戲分?jǐn)?shù)；當(dāng)玩家點(diǎn)擊“橡皮擦”時(shí)，可以擦除九宮格上指定位置的數(shù)字；當(dāng)玩家點(diǎn)擊“標(biāo)記”時(shí)，可以為九宮格上的格子添加一個(gè)小紅旗作為標(biāo)記。游戲界面上方有一個(gè)導(dǎo)航條，點(diǎn)擊house圖標(biāo)會(huì)回到主頁面。

二、實(shí)現(xiàn)

1. 先搭入口界面，包括一個(gè)image view和button，添加一個(gè)ViewController作為游戲界面，在入口界面和游戲界面之間添加segue，當(dāng)點(diǎn)擊“開始游戲”時(shí)跳轉(zhuǎn)到游戲界面。

2.為游戲界面添加必要的控件，用9x9個(gè)button實(shí)現(xiàn)九宮格，添加9個(gè)數(shù)字按鈕和3個(gè)功能控件，為了便于用戶使用，需要添加一個(gè)顯示條。通過用戶按下button得知玩家想要在九宮上填入數(shù)字的位置坐標(biāo)，button通過Tag識(shí)別。

3.關(guān)聯(lián)代碼。將九宮格，9個(gè)數(shù)字按鈕，以及3個(gè)功能控件與代碼關(guān)聯(lián)，同時(shí)新建一個(gè)Board類，Board類包含九宮格游戲進(jìn)度和答案計(jì)算等。
