问题
When trying to run my project I get this error and I don´t know what it means :
_OBJC_CLASS_$_MyWindowController", referenced from: objc-class-ref in AppDelegate.
ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
What does it mean and how can I get rid of it?
Any ideas?
回答1:
Select the application target, go to the Build Phases tab and make sure MyWindowController.m is in Compile Sources, otherwise add it.
Also, if you use a xib file associated with it, make sure it is in Copy Bundle Resources.
回答2:
Check to see if the framework that your MyWindowController object is based on has been added to your project.
Good luck!
