I understand what the warning says. This is exactly how scoping rules work. I appreciate that some people want a nanny. I don’t. How can I disable this warning?

The warning name you’re looking for is “shadow-ivar”. It appears in the log in Xcode 4.3 as something like
warning: local declaration of 'foo' hides instance variable [-Wshadow-ivar].I still don’t see it in the project’s Build Settings list, but
#pragma clang diagnostic ignored "-Wshadow-ivar"will take care of it in one file at a time. I actually like to turn it off for particular functions and then turn it on again. That way it ceases to nag me where I’ve decided I don’t care but will warn me again in new code.
