ios - Why don't some of Apple's sample code demos use storyboards? -

some of complicated sample code i've seen doesn't use storyboards, example theelements demo. i'm curious know why demo generates views programatically opposed using nib file or storyboards. understanding storyboards seem recommended practice of developing interfaces.

thanks

storyboards great when want create interfaces. apple sample code understanding what's going on, including understanding interface. interface builder has lot of options, it's tough see has been changed defaults.

even in of newer code samples, there no .xib files , makes grasping logic easier. of course, doesn't mean should follow example , use no ib files. starting learning long way has advantages.
