大家好。当我构建一个包含BSYahooFinance类的xcode项目时，我遇到了一个问题。此问题的详细信息：

体系结构i386的未定义符号：
"_OBJC_CLASS_$_SBJsonParser"，引用自：
YFStockSymbolSearch.o中的objc类引用
YFStockDetailsLoader.o中的objc类引用
ld:找不到体系结构i386的符号
clang:错误：链接器命令失败退出代码为1（使用-v查看调用）
我从谷歌上找到了很多答案，比如"在你的项目中找到.m文件"或"添加所需的框架"。我都试过了，但还是解决不了这个问题。你们中有人能给我一些建议吗？或者以前见过这个问题吗
您需要将SBJsonParser的i386对象文件链接到目标中。
