关于Cocos的内存管理机制引发一些异常的解决方案

GameController* GameController::create(Layer * scene) {
    GameController * _ins = new GameController();
    _ins->initWithScene(scene);
    _ins->autorelease();
    return _ins;
}

    _ins->autorelease();

GameController* ctrl;

Vector<GameController*> gcs;

ctrl = GameController::create(this);
gcs.insert(0, ctrl);

//向左移动
void GameController::moveLeft() {
    hero->setPosition(hero->getPositionX() - 50, hero->getPositionY());
}
