If you simply want to drag an object around a card, you can use the
following in an object script:
If you need to track anything during a drag, you can see some examples in a
drag sampler stack that is available by executing the following in your LC
go url "http://www.tactilemedia.com/site_files/downloads/drag_sampler.rev"
Since your target is iOS, you may need to substitute handlers with
touchStart/touchEnd, but the principles should be the same.
