I would have two seperate UIImageViews, one with the black and white version and one with color (and maybe a third with the red line.)
To generate the black and white version, I think you should look at CGFilters (I believe that's what they're called... I've experimented with them before but never used them in an actual app.)
Edit: oh, and I'd shift the bounds/frame around on whichever image is ontop when the slider is moving.

As a bit of a tip.
Top View = Redbar that you can touch (touchesBegin/touchesEnd methods).
Next View Down = Color Image
Next View Down = BW Image (CIFilters).
This would be the easiest approach with out doing partial image filters. is to use two image that you change the bounds just like @ArtOfWarfare suggested.
Any questions we would be happy to answer but not writing all the code for you.
As another suggestion you may check out http://cocoacontrols.com. They may have something similar to what you want.
Also if you would like to go with the approach of using a single image and filters you will need to use CIFilter Maps.
Here is a sample control after a little google time. http://www.cocoacontrols.com/platfor.../wcbeforeafter
