我总结了一下，下面是这三种方法的例子:

1. 使用while循环

list<int> lst{4, 1, 2, 3, 5};

auto it = lst.begin();
while (it != lst.end()){
    if((*it % 2) == 1){
        it = lst.erase(it);// erase and go to next
    } else{
        ++it;  // go to next
    }
}

for(auto it:lst)cout<<it<<" ";
cout<<endl;  //4 2

2. 在列表中使用remove_if成员函数:

list<int> lst{4, 1, 2, 3, 5};

lst.remove_if([](int a){return a % 2 == 1;});

for(auto it:lst)cout<<it<<" ";
cout<<endl;  //4 2

3.使用std::remove_if函数结合erase成员函数:

list<int> lst{4, 1, 2, 3, 5};

lst.erase(std::remove_if(lst.begin(), lst.end(), [](int a){
    return a % 2 == 1;
}), lst.end());

for(auto it:lst)cout<<it<<" ";
cout<<endl;  //4 2

4. 使用for循环时，应注意更新迭代器:

list<int> lst{4, 1, 2, 3, 5};

for(auto it = lst.begin(); it != lst.end();++it){
    if ((*it % 2) == 1){
        it = lst.erase(it);  erase and go to next(erase will return the next iterator)
        --it;  // as it will be add again in for, so we go back one step
    }
}

for(auto it:lst)cout<<it<<" ";
cout<<endl;  //4 2 

向后迭代避免了在要遍历的剩余元素上擦除一个元素的效果:

typedef list<item*> list_t;
for ( list_t::iterator it = items.end() ; it != items.begin() ; ) {
    --it;
    bool remove = <determine whether to remove>
    if ( remove ) {
        items.erase( it );
    }
}

PS:看看这个，例如，关于向后迭代。

PS2:我没有彻底测试它是否处理好擦除元素在结束。

我认为你有一个错误，我这样编码:

for (std::list<CAudioChannel *>::iterator itAudioChannel = audioChannels.begin();
             itAudioChannel != audioChannels.end(); )
{
    CAudioChannel *audioChannel = *itAudioChannel;
    std::list<CAudioChannel *>::iterator itCurrentAudioChannel = itAudioChannel;
    itAudioChannel++;

    if (audioChannel->destroyMe)
    {
        audioChannels.erase(itCurrentAudioChannel);
        delete audioChannel;
        continue;
    }
    audioChannel->Mix(outBuffer, numSamples);
}

你想做的是:

i= items.erase(i);

这将正确地更新迭代器，使其指向您删除的迭代器之后的位置。

你需要结合Kristo的回答和MSN的回答:

// Note: Using the pre-increment operator is preferred for iterators because
//       there can be a performance gain.
//
// Note: As long as you are iterating from beginning to end, without inserting
//       along the way you can safely save end once; otherwise get it at the
//       top of each loop.

std::list< item * >::iterator iter = items.begin();
std::list< item * >::iterator end  = items.end();

while (iter != end)
{
    item * pItem = *iter;

    if (pItem->update() == true)
    {
        other_code_involving(pItem);
        ++iter;
    }
    else
    {
        // BTW, who is deleting pItem, a.k.a. (*iter)?
        iter = items.erase(iter);
    }
}

当然，最有效和超级酷®STL精明的事情应该是这样的:

// This implementation of update executes other_code_involving(Item *) if
// this instance needs updating.
//
// This method returns true if this still needs future updates.
//
bool Item::update(void)
{
    if (m_needsUpdates == true)
    {
        m_needsUpdates = other_code_involving(this);
    }

    return (m_needsUpdates);
}

// This call does everything the previous loop did!!! (Including the fact
// that it isn't deleting the items that are erased!)
items.remove_if(std::not1(std::mem_fun(&Item::update)));

Kristo回答的循环版本的替代方案。

你会损失一些效率，你在删除的时候会向后再向前，但作为交换，你可以在循环范围内声明迭代器，代码看起来更干净一些。选择什么取决于当前的优先事项。

我知道这个答案完全过时了……

typedef std::list<item*>::iterator item_iterator;

for(item_iterator i = items.begin(); i != items.end(); ++i)
{
    bool isActive = (*i)->update();

    if (!isActive)
    {
        items.erase(i--); 
    }
    else
    {
        other_code_involving(*i);
    }
}
