Duplicate Symbol Error in Objective-C build?

Question

I got this error when I press build+debug:

ld: duplicate symbol .objc_class_name_BlogTableItemCell in /Users/fabian/Development/Workspaces/iphone_experiments         


        

Answer 1

It seems that you are compiling the same BlogTableItemCell class two times in different places of your code. This may happen in the following cases.

• You have put the same class implementation into two different files;

• You actually have just one implementation of this class, however you are also linking in your project a framework or library containing a class whose name is exactly the same of yours.

Try finding in the whole project your class and make sure only one copy is available within your project.
