xcode5-SDK7解决错误：invalid deployment target for -stdlib=libc++ (requires iOS 5.0 or later)

xcode5-SDK7编译出现错误：invalid deployment target for -stdlib=libc++ (requires iOS 5.0 or later)

想想copy的代码中有包含.cpp和.mm等文件混合编译，

编译选项需要修改。

解决：

-->Build Setting

-->Apple LLVM 5.0 - Language - C++

-->C++ Standard Library中选择libstdc++
