构建 cocos2d-x 3.15 时出现 Apple Mach-O 链接器错误：“_iconv_open”，引用自：cocos2d::FontAtlas::conversionU32TOGB2312()

Question

我正在努力将现有的 cocos2d-x 项目从 3.7 更新到 3.15，我运行遇到以下链接器错误：

    Undefined symbols for architecture arm64:
  "_iconv_open", referenced from:
      cocos2d::FontAtlas::conversionU32TOGB2312(std::__1::basic_string<char32_t, std::__1::char_traits<char32_t>, std::__1::allocator<char32_t> > const&, std::__1::unordered_map<unsigned int, unsigned int, std::__1::hash<unsigned int>, std::__1::equal_to<unsigned int>, std::__1::allocator<std::__1::pair<unsigned int const, unsigned int> > >&) in libcocos2d iOS.a(CCFontAtlas.o)
  "_iconv", referenced from:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

有什么想法可以解决这个问题吗？

构建 Xcode 9.0

谢谢！

更新：通过进一步探索，我发现我需要在我的项目中添加两个新框架：

导航到 Project->Build Phases->Link Binary With Libraries，并添加：

libiconv.tbd
CoreText.framework

解决了我的链接器错误。

将此留在这里以防其他人在从旧版本 cocos2d-x 更新时遇到类似问题。
