AIR for iOS View performance
In using FB4.6 with AIR 3.4 for iOS on Mac OS X 10.7.4 and when I run this on an iPad 2, one of my views is taking 3.2 secs before it's displayed. I've search for references to things to do to improve the performance
I have a View containing a TabbedViewNavigator with 2 tabs:-
<s:TabbedViewNavigator width="100%" height="100%">
<s:ViewNavigator label="tabOne" firstView="TabOneView" width="100%" height="100%"/>
<s:ViewNavigator label="tabTwo" firstView="TabTwoView" width="100%" height="100%"/>
</s:TabbedViewNavigator>
The the first view is:-
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
actionBarVisible="false"
title="TabOneView"
render="trace(DateUtils.currentTime()+'TabOneView.render')"
preinitialize="trace(DateUtils.currentTime()+'TabOneView.preinitialize')"
contentCreationComplete="trace(DateUtils.currentTime()+'TabOneView.contentCreationComplete')"
creationComplete="trace(DateUtils.currentTime()+'TabOneView.creationComplete')"
width="100%" height="100%">

What am I missing in terms of performance?
