I know for a fact that Apple does not use XIB for every interface, some stuff just requires custom code. I'd rather just code it in Obj-C than find out whether or not XIB works for this particular case. XIB files certainly do contain code, it's just interpreted by an NSCoding object instead of compiled into machine code, that's like saying a PHP file doesn't have code in it because there is something written in C that interprets it.
