令人困惑的向量迭代器不兼容的运行时错误

Question

所以这就是交易。 我这里有一个容器类，

#include "stdafx.h"
#include "ObjectManager.h"
#include "Game.h"

ObjectManager::ObjectManager()
{
}

ObjectManager::~ObjectManager()
{
   std::for_each(_objects.begin(),_objects.end(),ObjectDeallocator());
   std::for_each(_dynamicObjects.begin(),_dynamicObjects.end(),DynamicObjectDeallocator());
}


void ObjectManager::Add(std::string name, VisibleGameObject *object)
{
    _objects.insert(std::pair<std::string, VisibleGameObject*>(name,object));
}

void ObjectManager::Remove(std::string name)
{
    std::map<std::string, VisibleGameObject*>::iterator results = _objects.find(name);
    if (results != _objects.end())
    {
        delete results->second;
        _objects.erase(results);
    }
}

int ObjectManager::GetObjectCount() const
{
    return _objects.size();
}

VisibleGameObject* ObjectManager::Get(std::string name) const
{
    std::map<std::string, VisibleGameObject*>::const_iterator results = _objects.find(name);
    if (results == _objects.end())
        return NULL;
    return results->second;
}


void ObjectManager::AddDynamic(VisibleGameObject *object)
{
    _dynamicObjects.push_back(object);
}

void ObjectManager::PostRemoveDynamic()
{
        std::vector<VisibleGameObject*>::const_iterator iter = _dynamicObjects.begin();
    while(iter != _dynamicObjects.end())
    {
        if ((*iter)->IsDeleted())
        {
            delete (*iter);
            _dynamicObjects.erase(iter);
        }
    iter++;
    }
}

const std::vector<VisibleGameObject*>& ObjectManager::GetDynamicContainer()
{
    return _dynamicObjects;
}


void ObjectManager::DrawAll(sf::RenderWindow& renderWindow)
{
    std::map<std::string, VisibleGameObject*>::const_iterator itr = _objects.begin();
    while(itr != _objects.end())
    {
        itr->second->Draw(renderWindow);
        itr++;
    }

    std::vector<VisibleGameObject*>::const_iterator iter = _dynamicObjects.begin();
    while(iter != _dynamicObjects.end())
    {
        (*iter)->Draw(renderWindow);
        iter++;
    }
}

void ObjectManager::UpdateAll()
{
    std::map<std::string, VisibleGameObject*>::const_iterator itr = _objects.begin();
    std::vector<VisibleGameObject*>::iterator iter;
    iter = _dynamicObjects.begin();

    float timeDelta = GameEngine::GetWindow().GetFrameTime();

    while(itr != _objects.end())
    {
        itr->second->Update(timeDelta);
        itr++;
    }

    while(iter != _dynamicObjects.end())
    {
        (*iter)->Update(timeDelta);
        iter++;
    }

}

并且使用断点，我已经确定问题出在这个函数中，

void ObjectManager::UpdateAll()
{
    std::map<std::string, VisibleGameObject*>::const_iterator itr = _objects.begin();
    std::vector<VisibleGameObject*>::iterator iter;
    iter = _dynamicObjects.begin();

    float timeDelta = GameEngine::GetWindow().GetFrameTime();

    while(itr != _objects.end())
    {
        itr->second->Update(timeDelta);
        itr++;
    }

    while(iter != _dynamicObjects.end())
    {
        (*iter)->Update(timeDelta);
        iter++;
    }

}

具体来说，这一行，

    (*iter)->Update(timeDelta);

我的互联网搜索没有给出答案，所以现在我问你是什么导致了这个故障。如果有人需要的话我也会发布标题。另外，这是在线教程的修改课程。

编辑：错误消息来自向量类中的内置断言。（表达式：向量迭代器不兼容）

好吧，睡了一觉后我就明白了。作为对其他人的警告，问题来自于定义迭代器后更新的对象之一创建新的动态对象，使其无效。一旦我可以使用计算机，我将编辑一些代码来解释这一点。
