How to solve a & ldquo; dyld_stub_binder not found & rdquo; Error


I'm having problem building and running my app cause after an error message told me some plugin was missing. I googled the message and tried to add some files to my project (not longer sure what I did, just followed instruction). I then got like 15 warnings, so I undid it, but the app still doesn't run. The first warning says:

ld: warning: symbol dyld_stub_binder not found, normally in libSystem.dylib Undefined symbols for architecture armv7:

I've tried to find a solution and I've seen a couple of topics that is close to this one, but not the same. I reinstalled Xcode, and still no luck. I've tried some other projects and they are working so something has happened to my project.

I also get all kind of error messages, like:

"__objc_empty_vtable", referenced from:
_OBJC_METACLASS_$_BokbynAppDelegate in BokbynAppDelegate.o _OBJC_CLASS_$_BokbynAppDelegate in BokbynAppDelegate.o _OBJC_METACLASS_$_FirstViewController in FirstViewController.o _OBJC_CLASS_$_FirstViewController in FirstViewController.o _OBJC_METACLASS_$_AddresAnnotation in FirstViewController.o _OBJC_CLASS_$_AddresAnnotation in FirstViewController.o _OBJC_METACLASS_$_SecondViewController in SecondViewController.o "

change your Deployment Target to 4.0+
