pop_back（）是否真的使std :: vector上的* all *迭代器无效？

std::vector<int> ints;

// ... fill ints with random values

for(std::vector<int>::iterator it = ints.begin(); it != ints.end(); )
{
    if(*it < 10)
    {
        *it = ints.back();
        ints.pop_back();
        continue;
    }
    it++;
}
std::vector<int> ints;

// ... fill ints with r
