You're correct, but I certainly didn't expect that! From the Predicate Programming Guide: "The format string supports printf-style format arguments such as %x (see “Formatting String Objects”). Two important arguments are %@ and %K." But what can "%x" possibly mean in this context? Do you need to provide a hex-formatted C string or an integer? If the latter, how does this format specifier differ from "%d"? In practice, it looks like "%x" and "%d" are synonymous, and they mean you can provide a numeric argument. This is just an additional way this method differs from printf and NSLog, where %K isn't a valid format specifier. The Predicate Programming Guide needs to stop relying on half-true references to similar pieces of functionality when defining its grammar. It's been a woefully underspecified document for years. <rdar://problem/12076911> (Predicate Format String Syntax document is underspecified) --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
