“_OBJC_CLASS_$_”, referenced from: error in xcode 4.3.2

Question

So today I ran into a major problem. I got a problem involving my viewcontroller on xcode 4.3.2 as seen in this error message:

Undefined symbols for architecture         


        

Answer 1

For me the following method worked.

In target -> Build Phases -> Compile Sources I had all .m files including those that were giving issue.

Simply I removed those .m files which were giving issue.
