I'm not sure String::format is the best way to do this. I realize that this isn't performance critical code, but still probably not a great example to set.

What's the alternative? append '0' + pageNumber as a character literal?

Oh never mind, WTFString has a bunch of number conversion functions.

One alternative is to use StringBuilder and appendNumber. I don’t think it’s higher performance than String::format, but it does avoid the assumption that NSUInteger is always unsigned long, which this code makes by using %lu for it.
