Apple Mach-O-linker错误？

Question

亲爱的朋友们，我为Face，tiwitter和Emai添加了分享图片的BMsocial.framework。所以我添加了，然后构建项目，我得到了以下Apple Mach-O-linker错误。我使用的是Xcode4.5.1和iOS 6模拟器。

请任何人可以帮助我为这个错误，我是新开发的面书集成到iphone，如果它不是很好的框架，然后给我一些开发共享选项使用完整的教程

提前感谢

我不知道BMsocial.framework怎么样。对于ios5及以上版本，ShareKit是不错的选择。如果只针对iOS6，那么苹果已经添加了支持facebook、twitter分享的社交框架，请检查此http://getsharekit.com/install/。
