preventDefault() on working in Adobe Air for IOS

I have a few landscape-only apps that I use a handler such as you are to prevent the default and/or set it. I don't know if you're working in Flash Pro timeline or a separate class file but if you're working in a class file, just add the protection modifiers (protected/public/etc):

import flash.events.StageOrientationEvent; // this should be global either to Flash or a protected class var var stageOrientation:String = stage.orientation; // this is run during start-up init if (startOrientation == StageOrientation.DEFAULT || startOrientation == StageOrientation.UPSIDE_DOWN) {   stage.setOrientation(StageOrientation.ROTATED_RIGHT); } else {   stage.setOrientation(startOrientation); } stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGING, orientationChangeHandler); // this is run any time orientation is changed to assure it's correct function orientationChangeHandler(e:StageOrientationEvent):void {   if (e.afterOrientation == StageOrientation.DEFAULT || e.afterOrientation == StageOrientation.UPSIDE_DOWN)   {   e.preventDefault();   } }

On an iPad the default that I select in AIR becomes default and Apple will reject an app that cannot perform the upside down version of itself (since it's the same). So this just lets me check off to allow auto-orient, allows the user to spin either landscape side and simply prevents rotation if it's not my original selection.

The last time I compiled that app was AIR 17 and it is working fine. from OS 5 to OS 8
