我正在研究一個應用程序源代碼，該代碼由於某種原因禁用了In App Purchase代碼（註釋掉）。遊戲是在Cocos 2dx中建立的。In App在iOS遊戲中購買Cocos2Dx「使用未聲明的標識符」
現在，我對C++一無所知，但我研究過試圖找到對此的答案，並且我被卡住了。
我得到一個編譯器錯誤：
Undefined symbols for architecture arm64:

"BLACKJACK::BlackJackSetting::showLeaderboard()", referenced from:

MainMenuLayer::init() in MainMenuLayer.o
MainMenuLayer::onLeaderBoard(cocos2d::CCObject*) in MainMenuLayer.o
這裏是整個代碼塊：
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：
static void static_setEnable(bool enable){
NSLog(@"enable GC %d", enable);
BLACKJACK::BlackJackSetting *gc = BLACKJACK::BlackJackSetting::shared();
gc->isEnabled = enable;
}

你能顯示你的BLACKJACK類或名字空間的代碼嗎？ – Jain
用BlackJackSetting.m更新了問題 – Paul
爲什麼你需要一個名稱空間來保存類的靜態變量？ – Jain
