I've been using Flash CS5.5 targeting the IOS platform.
I have been writing a small application that relies on things being
dragged around - can't really say much more right now.
I need to know when dragging starts, so on the thing that's being
dragged I add a listener for TouchEvent.TOUCH_BEGIN.
I need to know when it's being moved, so the widget also has a listener
for TouchEvent.TOUCH_MOVE.
And finally, I need to know when dragging stops, so the widget listens
for TouchEvent.TOUCH_END.
Now mostly, everything goes OK, I get:
TOUCH_BEGIN, followed by one or more TOUCH_MOVE, and finally a
TOUCH_END. Happiness.
I have noticed that sometimes if I drag too fast and/or gently do a
swipe motion lifting my finger gently, the TOUCH_END doesn't seem to
happen, so the app doesn't know that the user has stopped dragging. For
the app, this is a problem because the user is allowed to position the
widget roughly and on TOUCH_END it should snap into place.
Anyone else seen this?
I can imagine a workaround using a timer to catch missing TOUCH_END
events, but it's a bit of a kludge.
