objective c - Are storyboards widely used on iOS apps? -

i developing ios framework other developers use. intend use "ecslidingviewcontroller" framework , add webview slide-up. have working on 2 projects use storyboards in it.

my search sample projects test framework raised big question. 9 out of 10 of samples didn't use storyboard.

so question is: should start developing framework non-storyboard apps or situation happening in sample projects.

what mean sample projects.

all applications prior ios 5.0 non-storyboard type.

if intend support versions prior 5.0 only, have leave out option support storyboard.

if supporting older 5.0 + versions have build storyboard non storyboard applications.
