my problem is very simple (at least I hope so).
When the book tells me to import a class, I always get the same two errors (with other classnames of course):
Undefined symbols for architecture i386:
"OBJC_CLASS_BNRItem", referenced from: objc-class-ref in BNRItemStore.o (maybe you meant: _OBJC_CLASS__BNRItemStore)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I really have no idea what causes these errors. When I create a new class instead and simply copy the old code into the new files, everything works fine.
I hope you have a solution for me
Have a nice day!
