架构 armv7 iOS 7.0 的未定义符号

Question

在 Xcode 中，当我使用 "Deployment Target" 6.0 或 6.1 构建应用程序时，它工作正常，但如果我将目标更改为 7.0 或更高版本，我会收到未定义符号错误。我试过删除框架并重新添加它，但似乎仍然无法构建它。不确定这是否有所作为，但我必须为此框架使用“-all_load”作为 "Other Linker Flags"。我还确保 "Valid Architectures" 包含 armv7，但我仍然无法弄清楚。任何人都可以帮助我或指出正确的方向吗？

Undefined symbols for architecture armv7:
 "std::ios_base::Init::~Init()", referenced from:
     __GLOBAL__I_a in G4XSwiper(DownSample.o)
     __GLOBAL__I_a in G4XSwiper(FskController.o)

 ld: symbol(s) not found for architecture armv7

尝试在其他Linker Flags中设置-ObjC -lstdc++或添加libstdc++ .6.dylib 在 Project->Targets->Build Phases-> Link Binary With Libraries.
