std::string content;
创建:

n = 3;// 0~3来获得一个中文字符
label = Label::create();
label->setString("");
label->setColor(Color3B::WHITE);
label->setSystemFontSize(40);
label->setPosition(Vec2(100, 500));
label->setAnchorPoint(Vec2(0, 1));//设置锚点,从左向右打印
label->setDimensions(800, 400);
this->addChild(label);

显示:

if (n > content.length())
{

}
去空格:
static void trim( std::string& str, bool left = true, bool right = true );
void trim(string& str, bool left, bool right)
{
static const string delims = " ";
if(right)
str.erase(str.find_last_not_of(delims)+1); // trim right
if(left)
str.erase(0, str.find_first_not_of(delims)); // trim left
}
