Question

程序无异常，执行出问题！

auto zyh = Director::getInstance();

Size visibleSize = zyh->getVisibleSize();

//创建场景
auto myScene = Scene::create();

//创建标签
auto label1 = Label::createWithTTF("MyGameTow","Marker Felt.ttf", 36);

label1->setPosition(Vec2(visibleSize.width / 2, visibleSize.height / 2));

myScene->addChild(label1);

auto sprite = Sprite::create("one.png");
sprite->setPosition(Vec2(100, 100));

myScene->addChild(sprite);


this->addChild(sprite);

return true;
