Build failed while using the static library file in Xcode 4.3.2,iOS
===

I am new to iOS.I created the static library file using http://www.icodeblog.com/2011/04/07/creating-static-libraries-for-ios/
When I using the static library file in another project it gives errors as 

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_Exact_Library", referenced from:
      objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
 Please help me where I did wrong.Thanks in advance.
