今天学习Objective c，发现简单的helloworld总是编译不通过，提示问题如下：
"_objc_msgSend", referenced from:
"_OBJC_METACLASS_$_NSObject", referenced from:
后来再网上搜索了一圈才发现，如果不是Mac工程，需要手动加入一个类库
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.
这样就搞定了，靠，浪费我时间，下次看来要按部就班了。。。
