If you're compiling for both 32 and 64-bit you should use %lu and cast to 'unsigned long'.
Thanks for that--I just figured it out a minute ago. I had changed my architecture setting to 32/64--changing it back to 32 solved the issue for now. So it seems that when trying to compile a fat binary you have to cast. What a pain.

Is anyone else seeing this? I get tons of warnings such as:
Format specifies type 'long' but the argument has type 'NSUInteger' (aka 'unsigned int')
when using %ld as a format specifier. If, however, I change the format specifier to %d as the warning (and the fix-it) would suggest, it changes the warning to:
Format specifies type 'int' but the argument has type 'long'
With this line in Xcode Build Settings:
OTHER_CFLAGS = -DNS_BUILD_32_LIKE_64=1 NS(U)Integer is (unsigned) long for both 32 and 64 Bits. So that %lu / %ld works for both without warnings without any castings.
