I am trying to make an app similar to this one where the user scrolls horizontally and the value changes. See pics.

I have used UItableView and UIScrollView before. I am not sure how is this being accomplished? I mean in a UITableView the user needs to select a cell for the value to change. In this case just by scrolling left or right the values are changing. Once I let go it stops to the nearest cell. Kinda like UITableView. So how is this being accomplished? I am stumped.

Update: Upon further looking it looks like they have implemented some sort of scrollview that behaves like UISlider. Again I have no idea how that is done.
