Question

我已经获得了这行代码

for (auto view : views)
{
    view->update(deltaTime);

    if (view->isDead())
    {
        trash.push_back(view);
        removeChild(view, true);
    }
}

它在removeChild(view, true);行打破。

这是我的堆栈跟踪。

我无法从我那里得到它想要的东西。它称视图为析构函数，它就是它！巴姆！哗啦啦！视图的析构函数是空的，我完全迷失了。

我打赌你已多次调用该代码。

然后，在您调用removeChild（view，true）一次后，自动视图已被删除，并且您尚未从视图中删除视图。当然，当你这样做时，程序会崩溃，因为你试图删除已经删除的视图。

如果我猜错了，您需要发布更多代码。

P.S：你的代码风格在Cocos2d-x中不是很好。您不需要像Java一样收集垃圾。您需要在Cocos2d-x中学习内存管理。

Cocos2d-x removeChild工作很奇怪
