objective c - Custom selection mechanism -

-

i'm trying create little slider mechanism operates box/view static line image in center , behind pins. pins marks on ruler. when slide marks left or right; keep coming continuously (a loop). , need use controller of view, selector. needs scroll through list when pins slid. how can put together?

create uiview , add uiswipegesturerecogniser it. when swipe occurs update ivar , either redraw or animate bunch of repeating uiimageview subviews.

the latter preferable efficiency , smoothness.
