崩潰在參考::發佈（）在android cocos2d-x

Question

我正在cocos2dx v3.3上工作。無論何時使用Release或autorelease發佈圖像，然後在Android中發生隨機崩潰，但它在iOS中工作得很好。

任何人都可以幫助或指導我如何處理這些崩潰？

cocos2d-x爲存儲器管理實現了類似OC的引用計數方案。 這種崩潰通常是由錯誤的引用計數造成的。當你release或autorelease a Ref，你應該確保之前已經編輯了retain，以便其引用計數不爲零。

進一步的細節，可以參考下面的代碼片段從CCRef.cpp（注：評論是更重要）：

void Ref::release() 
{ 
    CCASSERT(_referenceCount > 0, "reference count should be greater than 0"); 
    --_referenceCount; 

    if (_referenceCount == 0) 
    { 
#if defined(COCOS2D_DEBUG) && (COCOS2D_DEBUG > 0) 
     auto poolManager = PoolManager::getInstance(); 
     if (!poolManager->getCurrentPool()->isClearing() && poolManager->isObjectInPools(this)) 
     { 
      // Trigger an assert if the reference count is 0 but the Ref is still in autorelease pool. 
      // This happens when 'autorelease/release' were not used in pairs with 'new/retain'. 
      // 
      // Wrong usage (1): 
      // 
      // auto obj = Node::create(); // Ref = 1, but it's an autorelease Ref which means it was in the autorelease pool. 
      // obj->autorelease(); // Wrong: If you wish to invoke autorelease several times, you should retain `obj` first. 
      // 
      // Wrong usage (2): 
      // 
      // auto obj = Node::create(); 
      // obj->release(); // Wrong: obj is an autorelease Ref, it will be released when clearing current pool. 
      // 
      // Correct usage (1): 
      // 
      // auto obj = Node::create(); 
      //      |- new Node();  // `new` is the pair of the `autorelease` of next line 
      //      |- autorelease(); // The pair of `new Node`. 
      // 
      // obj->retain(); 
      // obj->autorelease(); // This `autorelease` is the pair of `retain` of previous line. 
      // 
      // Correct usage (2): 
      // 
      // auto obj = Node::create(); 
      // obj->retain(); 
      // obj->release(); // This `release` is the pair of `retain` of previous line. 
      CCASSERT(false, "The reference shouldn't be 0 because it is still in autorelease pool."); 
     } 
#endif 

#if CC_REF_LEAK_DETECTION 
     untrackRef(this); 
#endif 
     delete this; 
    } 
}
