c++ - Cocos2Dx "use of undeclared identifier"iOS游戏内购

Question

我正在处理一个应用程序源代码，由于某种原因禁用了应用程序内购买代码(已注释掉)。该游戏是在 Cocos 2dx 中构建的。

现在，我对 C++ 一无所知，但我进行了研究，试图找到这个问题的答案，但我被困住了。

我遇到编译器错误:

Undefined symbols for architecture arm64:

  MainMenuLayer::onLeaderBoard(cocos2d::CCObject*) in MainMenuLayer.o
  "BLACKJACK::BlackJackSetting::showLeaderboard()", referenced from:

  ShopLayer::onClickPopBuy() in ShopLayer.o
  MainMenuLayer::init() in MainMenuLayer.o
  MainMenuLayer::onLeaderBoard(cocos2d::CCObject*) in MainMenuLayer.o

这是整个代码块:

void ShopLayer::onClickPopBuy()  {

   if (g_nProgressBuy != -1) {
     itemPopBuy->setEnabled(false);
     AndroidSocial::shared()->buyFeatureB(m_curPopIdx);
     g_nProgressBuy = -1;
     this->schedule(schedule_selector(ShopLayer::onProcessBuy), 0.5f);
   }

   if ( spPop1->isVisible() ) {
    // Compiler Error: use of undeclared identifier 'BLACKJACK'
    BLACKJACK::BlackJackSetting* bj = BLACKJACK::BlackJackSetting::shared();
      if ( bj->isPaidVersion() ) {
        bj->processIAP("com.prismstudios.BlackjackPaid.coin1000");
      }
      else
      {
        bj->processIAP("com.prismstudios.Blackjackfree.coin1000");
      }

      GameSetting* gameSetting = GameSetting::shared();
      gameSetting->getCoins();

      if ( bj->isCoins1000() ) {
        g_nYourCoin += 1000;
      }

      gameSetting->saveCoins();
     }
   }

更新 - BlackJackSetting.m 文件:

  NSLog(@"enable GC %d", enable);

  BLACKJACK::BlackJackSetting *gc = BLACKJACK::BlackJackSetting::shared();
  gc->isEnabled = enable;

看起来这段代码是从其他项目导入的。 BLACKJACK 是定义引用范围的命名空间。您需要一个用于 BlackJackSetting 的类(即它的所有代码)。您可能根本不需要命名空间 (BLACKJACK)。
