我有一个应用程序，在其中一个模块中，它将导入两个库。1) OpenGLES.framework 2) QuartzCore.framework。

以作图为目的。但我有一个单独的绘图应用程序，效果很好。当我将它添加到我的应用程序时，它会给出“构建失败”。

我已经通过许多链接进行纠正，例如http://stackoverflow.com/questions/7953168/symbols-not-found-for-architecture-armv6/10415850#10415850

http://stackoverflow.com/questions/6251111/classlayerclass-wont-work

甚至删除了库，我再次添加了这些链接中所述的配置。但我仍然遇到同样的错误。

这是我的错误页面。
