碰到一个类似上述的问题，感觉还是stl的C++库加载造成的问题。
即使通过gcc -v查看了编译过程，
然后用gcc -E 导出了预编译后的文件，
查看到的仍然只是std::string，为什么会出现接口中
有的是fucn(std::string)
有的是func(std::__1::basic_string...)
仍然没有搞清楚，网上有一篇似乎可以处理这个问题的文章，如下：
http://blog.csdn.net/kaizi318/article/details/10362673
但是尝试后，发现xcode仍然报错。
通过在后台用nm查看调用。
发现如果用libstdc++库，则需要使用指定头文件，添加头文件路径如下：
-I $(shell $(XCRUN) --show-sdk-path)/usr/include/c++/4.2.1
其对应使用的std::string类型就是std::string。
而若是不指定用libstdc++，而是使用默认的libc++库，则使用的是默认的C++头文件，
其对应使用的std::string变成了std::__1::basic_string(........)之类的
因此，c++头文件使用的不同导致其他使用stl的库的函数签名和实现都不同了
参考文章如下：
Undefined symbols for architecture i386或者armv7: “_OBJC_CLASS_$_XXX
Undefined symbols for architecture i386:
“_OBJC_CLASS_$_XXX”, referenced from:
objc-class-ref in XXX
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
如果真机调试就是 undefined symbols for architecture armv7错误！
发生这种错误通常是project.pbxproj这个文件引起的，尤其在多人合作开发的时候，svn提交不规范可能导致project.pbxproj发生错误，导致文件的引用不在project.pbxproj文件中。
xcode项目import文件会根据project.pbxproj来查找，查找不到文件的引用则会有上述的错误。
解决方法点击工程，在主界面中点击Build Phases，根据提示信息“XXX”来判断缺少什么文件，一般如果缺少自定义的文件，XXX会是缺少的类名，那么就在Complie Sources中加入该文件。如果缺少类库，则在Link Binary With Libraries中加入该类库。

看着就非常复杂！有这么多的link STL的错误。其实，就是你编译静态库的时候使用不同版本的标准库， C++ Standard Library
那么如何fix掉这个issue呢？看下面这两张图！
如果你这两个在编译静态库和在使用静态库的app中设置的是一样的，应该就可以解决掉这个问题！
事实上，compiler default 足够了。

今天，使用了第三方一个库，结果，出现，iOS Undefined symbols for architecture armv7 std::basic_string<char, std::char_traits<char>
注意：不是修改Build Setting里面的设置，而是添加一个libstdc++.dylib, 搞定！
