首先需要将C++类中的CPP后缀名改为.mm
然后在导入oc类的头文件之前需要判断是否为IOS平台，若是则导入
对OC窗体的添加首先要获得glview 导演类的单例对象调用getOpenGLView()函数在调用getEAGLView()获得GLview窗口
之后创建一个窗体（按照oc的方法）

glview相当于根视图，将创建的窗体添加上去

话不多说，直接撸代码：

void HSpriteCPP::addView(){

    // 首先获取GLview窗口

    auto view = cocos2d::Director::getInstance()->getOpenGLView();

    auto eageview = (CCEAGLView*) view->getEAGLView();

    

    float screenWidth = Director::getInstance()->getWinSize().width;

    float screenHeight = Director::getInstance()->getWinSize().height;

    

    CGRect frame;

    frame.origin.x = 0;

    frame.origin.y = 0;

    frame.size.width = screenWidth;

    frame.size.height = screenHeight;

    

    UIView * tview = [[UIView alloc]initWithFrame:frame];

    [tview setUserInteractionEnabled:NO];

    [eageview addSubview:tview];

    

    UILabel *  label = [[UILabel alloc]init];

    label.frame = CGRectMake(0,200, 320,50);

    label.backgroundColor = [UIColor blackColor];

    label.textColor = [UIColor whiteColor];

    label.textAlignment = NSTextAlignmentCenter;

    label.textAlignment = NSTextAlignmentCenter;

    label.text = @"这是一个Label";

    [eageview addSubview:label];

      

}
