Question

嗨大家好。我在構建一個包含BSYahooFinance類的xcode項目時遇到了問題。 這個問題的細節：

Ld /Users/yxu/Library/Developer/Xcode/DerivedData/exchange-avxwiknpprmcnlhgjynxlmbwglpm/Build/Products/Debug-iphonesimulator/exchange.app/exchange normal i386
cd /Users/yxu/Documents/project/exchange
setenv IPHONEOS_DEPLOYMENT_TARGET 6.1
setenv PATH

Undefined symbols for architecture i386:

"_OBJC_CLASS_$_SBJsonParser", referenced from:
objc-class-ref in YFStockSymbolSearch.o
objc-class-ref in YFStockDetailsLoader.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我發現有很多的答案，如「尋找.m文件是在您的項目」或「添加所需的framworks」從google.I嘗試所有這些，但仍無法解決這個問題。你有什麼人可以給我一些建議或看到這個問題嗎？

Answer 1

您需要鏈接一個胖二進制文件和SBJsonParser的i386目標文件到目標文件中。
