IOS scroller

I spent a lot of time trying to do this on iOS and gave up (I was working with a per day calendar style scrolling object that you would swipe to change days). It worked some/most of the time but like you say, scrolling seems to override everything else. I even tried disabling scrolling until you had worked out whether you were scrolling or swiping but that was a dead end as well. Sorry - that's not very helpful though.

    Plodding through my own issues today: the above is marginally 
    inaccurate. Swiping horizontally does work but only if the scroller is 
    absolutely still. If you swipe even slightly upward (but mostly 
    horizontal) it acts like a vertical scroll. One of those scroller 
    properties I mentioned should be preventing that, right?
