Time for action – adding retina support

This time we'll work with the class AppDelegate.cpp:

Go to AppDelegate.cpp (you'll find it in the Classes folder). Inside the applicationDidFinishLaunching method, and below the director->setAnimationInterval(1.0 / 60) line, add the following lines:

auto screenSize = glview->getFrameSize();
auto designSize = Size(768, 1024);
glview->setDesignResolutionSize(designSize.width, designSize.height, ResolutionPolicy::EXACT_FIT);

std::vector<std::string> searchPaths;
if (screenSize.width > 768) {
    searchPaths.push_back("hd");
    director->setContentScaleFactor(2);
} else  {
    searchPaths.push_back("sd");
    director->setContentScaleFactor(1);
}
auto fileUtils = FileUtils::getInstance();
fileUtils->setSearchPaths(searchPaths);

Save the file.
