iOS静态库不链接XCODE 5 iOS 7

1o我创建了一个使用Cmake使用OpenCV2.framework foo的项目,使用foo.a创建一个XCode项目.我的可执行文件链接OpenCV2.framework foo.a并且完美地工作,编译和链接.

2o我用Ogre的模板创建了另一个项目.这个项目工作得很好.

3o然后,我尝试将foo.a添加到新项目中,以创建与我在第1步中使用的可执行文件相同的内容.

>添加包括标题搜索路径的路径.
>将库路径添加到库搜索路径.
>将-ObjC -all_load -lfoo添加到其他链接器路径,如This和this
>添加项目中所需的代码源.
>当我使用foo函数调用时 – >链接问题：架构armv7到foo :: functionname()的未定义符号.

>信息：
>那个电话就像第一个项目那样有效.
>使用otool -hv foo.a – >我看到cputype是所有lib.o的ARV V7
>使用lipo -info foo.a – >当我使用那个拱门时,我看到foo.a是armv7或armv7s.
>使用nm foo.a | grep functionname – >我在编译两个arch时看到函数在armv7和armv7s中的库中.

那么,如果库在另一个项目中工作,并且函数在里面,为什么链接问题呢？

>信息2：
>将foo目标添加到食人魔的项目中,同样的问题.遵循THIS方法.
>添加目标依赖项也不起作用.
