如何初始化C++的static Vector 类型的变量

_init_static_Vector.h:

private:

static std::vector mStrings;
static bool _init;

static bool init();

_init_static_Vector.cpp:

std::vector _init_static_Vector::mStrings;
bool A2dpProfile::_init = _init_static_Vector::init();

bool _init_static_Vector::init(){
   mStrings.replaceAt("No1",0);
   mStrings.replaceAt("No2",1);
    return true;
}
