这是在debug窗口中显示的，不过程序并没报错，但是运行时图片不显示。。。。

我觉得不会是简单的图片不存在问题，因为res中确实存在。

我是在进行各种分辨率的机型匹配时遇到的问题

就是
auto fileUtils = FileUtils::getInstance();
auto screenSize = glview->getFrameSize();
std::vectorstd::string resDirOrders;

// check which assets the devices requires
if (2048 == screenSize.width || 2048 == screenSize.height) // retina iPad
{
    resDirOrders.push_back("ipadhd");
    resDirOrders.push_back("ipad");
    resDirOrders.push_back("iphonehd5");
    resDirOrders.push_back("iphonehd");
    resDirOrders.push_back("iphone");
    
    glview->setDesignResolutionSize(1536, 2048, ResolutionPolicy::NO_BORDER);
}
else if (1024 == screenSize.width || 1024 == screenSize.height) // non retina iPad
{
    resDirOrders.push_back("ipad");
    resDirOrders.push_back("iphonehd5");
    resDirOrders.push_back("iphonehd");
    resDirOrders.push_back("iphone");
    
    glview->setDesignResolutionSize(768, 1024, ResolutionPolicy::NO_BORDER);
}
else if (1136 == screenSize.width || 1136 == screenSize.height) // retina iPhone (5 and 5s)
{
    resDirOrders.push_back("iphonehd5");
    resDirOrders.push_back("iphonehd");
    resDirOrders.push_back("iphone");
    
    glview->setDesignResolutionSize(640, 1136, ResolutionPolicy::NO_BORDER);
}

来判断应该查找图片的路径。有没有朋友遇到过
