I need to override a method in a category. I know I'm not supposed to do it but and I don't except in one place which is legacy code and I need it to keep working. Yesterday, everything was working fine. This morning, I upgraded to Xcode 4.3 and now I'm getting more warnings (warnings == errors) including 

category is implementing a method which will also be implemented by its primary class [-Werror,-Wobjc-protocol-method-implementation]

I cannot find anything on -Wobjc-protocol-method-implementation anywhere. What I am hoping to do is disable the warning on just that class but I don't know what the compiler flag is. I really do not want to turn off warnings == errors but that's what I have to do for now.

-Wobjc-protocol-method-implemetation /is/ the compiler flag your looking for. Or more specifically, -Wfoo turns on a warning, -Wnofoo turns it off. You can also use a #pragma to disable warnings in particular places (which is what I would probably do for this specific warning) but I don't recall the specific syntax – you should be able to find it on llvm.org in the docs for Clang.
