cocos2d-x 是一款基于 c++/Opengl 的强劲跨平台引擎，通过一次编码，你可以同时用于 android ， iOS 等大多数主流平台。这使得多平台的开发更加方便。虽然比起带团 cocos2d-x 的有名的兄弟 -cocos2d-iphone ， -x 还很年轻并缺少教程，但是由于团队的不懈努力，使得 -x 逐渐完善并不断被市场认可。
如果你想把 UIKit 折腾进 Cocos2d-x ， Github 有一个开源工程，推荐给大家学习没袜一下： open source project on GitHub .
相反，如果你想把 coocs2d-x 折腾进 UIKit (UIVIewController)，以下是详细步骤：
0. 废话少说，这里是本文的示例代码： Sample project Cocos2dxOnUikit.zip .
1.我们有一个 UIKit 工程，同时希望在某一个 view controller中显示Cocos2d-x （OpenGL view）。
2. 下载 Cocos2d-x 代码（哥说了句废话，你知道该去哪下载的）
3. 解压（废话 again ）
4. 创建工程，如果你不会，推荐看看泰然以往的教程。
5. 移除cocos2dx/platform/目录下的CCImage.cpp 和 CCThread.cpp
6. 打开 xcode 的项目配置，点击 build Settings ，在 “ Library Search Paths ” 参数添加$(SRCROOT)/cocos2dx/platform/third_party/ios/libraries/(为了在cocos2dx中使用curl库)
7. 接着，在“ Headers Search Paths ” 参数添加
$(SRCROOT)/cocos2dx and $(SDKROOT)/usr/include/libxml2 (为了蠢察橘使用libxml 库)
8. 在 “ Other C++ Flags ” 参数添加-DCC_UNDER_IOS
9.从HelloWorld示例工程中拷贝AppDelegate.cpp 和 AppDelegate.h并添加到我们现在这个工程中。
#import <UIKit/UIKit.h>是objective-c文件才能使用的，你不会从c++文件调用了吧。
如果是这个原因，你可以换用cocos2d-iPhone。
或者写wrapper class（与native Objective-C class 交流）需要写wrapper class可以继续问。
stdio 全称是 standard input and output 标准输入输出。所以你的程序里如果用到了scaf pritf getchar等输入输出时就应该亏颂把这个头文件包含进去；
math 是一些数枣空肆学函数，凳轿如pow sin sqrt（二楼你错拉）等；
