我正在尝试运行我的 cocos2d 应用程序并遇到此错误，因为我最近将我的 sdk 升级到 4.2 并将我的 cocos2d 升级到 0.99.5.

I am trying to run my cocos2d application and facing this error, as I have recently upgraded my sdk to 4.2 and my cocos2d to 0.99.5.

我尝试清理我的项目，甚至更改目标 ios 部署，但错误仍然存​​在.还要重命名 className 以避免与 cocos2d 的库类名称重复.

I tried to clean my project even change the Target ios Deployment but error remains the same. Also rename the className aswell in order to avoid duplication from Library classes names of cocos2d.

推荐答案

您正在链接文件 MenuScene.m 两次.您显然在静态库和主应用程序中都有它.

You are linking the file MenuScene.m twice. You apparently have it in a static library and also in your main application.
