今天學習Objective c，發現簡單的helloworld總是編譯不通過，提示問題如下：
"_objc_msgSend", referenced from:
"_OBJC_METACLASS_$_NSObject", referenced from:
后來再網上搜索了一圈才發現，如果不是Mac工程，需要手動加入一個類庫
Sounds like you didn't link against the Foundation framework. Go to Project -> Add To Project... and then add /System/Library/Frameworks/Foundation.framework to the project. Then, your app should compile.
這樣就搞定了，靠，浪費我時間，下次看來要按部就班了。。。
