重复符号_OBJC_METACLASS _ $ _ ClassName [英] duplicate symbol _OBJC_METACLASS_$_ClassName

问题描述

我试图运行我的cocos2d应用程序，并面对这个错误，因为我最近升级我的sdk到4.2和我的cocos2d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.

清理我的项目甚至更改目标ios部署，但错误保持不变。还要重命名className aswell，以避免从cocos2d的库类名重复。

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.
