Where did you find this info? I've seen mention of them, but never an official type doc that lists them.

General information on format specifiers is here:

I use %td for NSInteger and %tu for NSUInteger. The 't' is a length modifier specifying that a following d, o, u, x, or X conversion specifier applies to a ptrdiff_t or the corresponding unsigned integer type argument. That allows you to use the same format specifier for both 32- and 64-bit platforms, get the correct results, and avoid compiler warnings.
