前言:最近公司部門在組織團建,需要準備準備兩個團建小遊戲, 分別是“數字速算升級版”和“你話我猜升級版”

小編琢磨了一下,發現這個兩個小專案很適合入門iOS,故這篇文章誕生了。 本篇將介紹 iOS 小遊戲專案——數字速算升級版。 希望通過這篇文章,能夠幫助對iOS感興趣的同學快速入門iOS。

效果圖如下:

效果圖

一、專案需求

  1. UI層面: 8個Label,3個Button。

圖解:

UI

  1. 邏輯層面:

    • 點擊出題/開始按鈕,隨機生成三個數(兩位數及以下)和兩個運算子(加、減、乘)。
    • 做一個計時器,從0開始計時,直到遊戲結束,檢視遊戲時長。
    • 點擊出題,重新整理題目。
    • 點選結果,計算出結果。
    • 點選開始按鈕,出現一個彈窗,點選確定,開始計時。
  2. 難題概率:

    • 個位數出現的概率比兩位數高。
    • 乘法出現的概率比加減法低。

二、實現思路

  1. UI層面:
  • 方式一:storyboard(拖控制元件、加約束)。
  • 方式二:純程式碼。

專案中,我選擇的storyboard。獨立開發時,用storyboard比較高效。

@property (weak, nonatomic) IBOutlet UILabel *factorLabel1;//!< 數字Label1
@property (weak, nonatomic) IBOutlet UILabel *factorLabel2;//!< 數字Label2
@property (weak, nonatomic) IBOutlet UILabel *factorLabel3;//!< 數字Label3
@property (weak, nonatomic) IBOutlet UILabel *operatorLabel1;//!< 運算子Label1
@property (weak, nonatomic) IBOutlet UILabel *operatorLabel2;//!< 運算子Label2
@property (weak, nonatomic) IBOutlet UILabel *resultLabel;//!< 結果Label
@property (weak, nonatomic) IBOutlet UILabel *recordingLabel;//!< 計時Label
@property (weak, nonatomic) IBOutlet UIButton *questionButton;//!< 出題Button
@property (weak, nonatomic) IBOutlet UIButton *resultButton;//!< 結果Button
@property (weak, nonatomic) IBOutlet UIButton *startButton;//!< 開始Button

    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
    UIAlertAction *confirmAction = [UIAlertAction actionWithTitle:sender.currentTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        
        sender.selected = !sender.selected; 
        self.resultButton.enabled = !self.resultButton.enabled;
        
        if (sender.selected) {
            [self resetElements];
            [self startTimer];
        } else {
