I have several AIR 3.2 / Away3D 4 projects that work just fine on Android. (great in fact) However, every application I install on iOS just yields a white screen. I’ve seen this issue mentioned in other posts but I’ve not yet seen a solution.

I’ve tried a number of things, such as setting the depthAndStencil value to true & false, etc. Nothing appears to work.

I am using:
Flash Builder 4.6
Away3D 4.0 beta
AIR 3.2

Thoughts?

<renderMode]]>direct</renderMode>
<depthAndStencil>true</depthAndStencil>
in the application descriptor

Make sure -swf-version=15 is set in compiler arguments

When loading the scene into a spark.components.View component remember to set the View’s backgroundAlpha = 0 or if using spark.components.Application as your main app set that backgroundAlpha = 0

works for me.

The following DOES NOT work on iOS: (iPad 2)

- Flash Builder 4.6
- AIR 3.2 SDK
- backgroundAlpha=“0” (Flex s:Application)
- -swf-version=15 (compiler argument)
- <renderMode>direct</renderMode>
- <depthAndStencil>true</depthAndStencil> (false does not work either)
- <requestedDisplayResolution>high</requestedDisplayResolution>
- <fullScreen>false</fullScreen> (true does not work either)

Note: The application works fine on Android.

**To clarify, even with all these settings, the application on iOS yields only a white screen.

One thing I noticed when I was getting this to work - and it is working here with exactly the same setup you have - is that the Event.ENTER_FRAME event wasn’t firing correctly. You might want to check that in debug mode if you can or put a textfield on stage and trace into it. The only solution I found - and this is weird - was to call view.render() immediately after creating my scene. So I have something like this:

initView();
initLights();
initCamController();
initListeners();
initScene();

_view3D.render();

It’s odd because there should be no way this would affect ENTER_FRAME events - but it worked for me..

I’ll give that a shot and see if it works.

This sounds like a somewhat serious bug - especially if you’re targeting iOS.

YES, this appears to be the solution.

I put a single view.render() line right after I added it to the mx:UIComponent.  The issue does, in fact, appear to be the enter frame event.

So, for all you folks like me who’ve had this white screen on iOS, this is the answer. I think the Away3D folks should pay attention to this as well.

Thanks artpluscode.

I can’t find the way to fix it, I am having the same problem and use any possible solution but still no luck. My friends that is working at http://www.kekacase.com/designer-cases/kate-knight.html told me to check the configuration properly but still the same.

This solution worked for me too. I’m a junior developer at mobile app development company usa and we applied this solution to several IOS apps we built.
