iOS: performance issues with visual effects

[William de Smet]

Hi Chris,

I am experiencing the same thing (iPad 1) here with LC 5.02.

I just use:
visual effect push left
go cd "start"

There is no delay in the IDE but there is with an compiled app on iOS 5.
Sadly I don't have an solution :-( .........


groeten,

William

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.

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?
