This was posted on the xcode list a while back by Quincey Morris:
"As suggested by Greg Parker on this list a couple of years ago, you can use
%t… (%td, %to, %tu %tx, %tX) for unsigned results
%z… (%zd, %zo, %zu %zx, %zX) for signed results
and these work on NS[U]Integer-sized variables on all platforms and
architectures that are supported by Apple (without having to cast the
parameters).”
They are documented in (all version I think) of the String Programming Guide.
