This is a problem that I have run into before and have never been able to solve 
satisfactorily. I’m using touchStart and touchEnd handlers to detect the 
direction and speed of a finger movement and if it is within certain bounds 
(large enough x, small enough y, and fast enough) then the user can swipe back 
and forwards through a series of cards. Good so far except when the area they 
are swiping on also includes a mobile scroller (to scroll a list selection 
widget/thingy). In that situation the swiping becomes a bit of a hit and miss 
thing – works sometimes but not others. On iOS there are a few scroller 
parameters look potentially useful (canCancelTouches, delayTouches, and 
lockDirection) but it’s not really clear (to me at least) which of these might 
help and if so whether I should be setting them to true or false.

Any ideas?
