Working on an iPad app that uses visual effects in a few places to make things
a little more pleasing for the user. But I'm noticing some strange lags between
the time I tap and the time the effect actually happens.
For example, in one place I have a text field set up with several different
"links". The user taps a link, and then a "window" pops up to show a definition
of the tapped word and play an audio file. When I show/hide the "window" I'm
using a dissolve visual effect:
show/hide group "window" with visual effect dissolve very fast
The effect happens, but sometimes there is a 2 or 3 second delay between the
tap on the screen and the change on the screen. There is some code that runs
inside a linkClicked handler before the group is shown, but nothing that should
take that long. And if I remove the visual effect, the "window" displays almost
instantly. Something is occurring as part of displaying the visual effect that
is taking longer than expected.
So the question is, is there anything I can do to improve this? I've already
set the layerMode to "dynamic" where appropriate, but this doesn't seem to make
much difference in this case. Maybe I haven't set the property on the correct
objects? Some visual effects seem to work just fine, like the basic push and
reveal effects. But I have also noticed this somewhat with the curl effects.
Has anyone else experienced this? Any suggestions to improve performance?
Currently working on an iPad 1, btw.
Thanks,
Chris
