+[NSNumber numberWithUnsignedInteger:] Literal?

Question

I know I can do @3 instead of [NSNumber numberWithInt:3]
but what's the literal for [NSNumber numberWithUnsignedInteger:3]?

Answer 1

You can use @3U or @3UL (or use the usual integer suffixes to change the type, e.g. @3ULL for unsigned long long).

See this page for more information on NSNumber literals.
