|-Wselector |(Objective-C and Objective-C++ only)
Warn if multiple methods of different types for the same selector
are found during compilation. The check is performed on the list of
methods in the final stage of compilation. Additionally, a check is
performed for each selector appearing in a |@selector(...)|
expression, and a corresponding method for that selector has been
found during compilation. Because these checks scan the method table
only at the end of compilation, these warnings are not produced if
the final stage of compilation is not reached, for example because
an error is found during compilation, or because the -fsyntax-only
option is being used.
same selector - return types are different.
The selector is only the 'something:' bit, it doesn't encode the return
type or the argument types, so in dynamic binding selectors are required
to have the same signature.

Why on earth am I getting a warning
warning: multiple methods named '-something:' found
using...
also found...
They are on different objects. Should be obvious there is no problem.
Is this really just a "careful - you sure you picked the right one?"
Or what am I missing?
cheers
