Hi folks, Here is the issue I found, I'm still trying to solve it, but may need some help:
1. Using Flex SDK Installer 3.1 to install Flex SDK 4.13.0 + AIR 15 + FP 15 beta. 2. Open Flash Builder 4.7 to use the Flex SDK 4.13.0, and create a very simple Flex Mobile Project. 3. In the main application mxml, use this code: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"> <s:RadioButton label="Do you see me?" fontSize="48" horizontalCenter="0" verticalCenter="0"/> </s:Application> 4. Use Flash Builder 4.7 to [Export Release Build], target at Apple iOS, press [Next], then press [Customize Launch...], add -useLegacyAOT=no to the packaging parameter, place it before -provisioning-profile parameter, press [OK], and then set all other stuff, press [Finish] to pack the Flex app to IPA file. 5. When finished, setup the IPA to iPhone or iPad device, and run the app on the iDevice. 6. On iDevice, you will see only a blank screen hanging there forever. This issue will not happen when -useLegacyAOT=yes on iOS devices, and on desktop device the issue will not happen too. I cross checked the RadioButton.as source code and the known issues in the new AIR IPA packager (-useLegacyAOT=no): http://helpx.adobe.com/air/kb/unable-update-air-mac-os1.html Still I cannot find a clue... If we cannot resolve this issue, we will have to use the old AIR IPA packager, and wait 5-15 minutes to pack the IPA every time, which is insane and totally wasting of time. I will continue investigate the issue, I'll keep you guys posted, and if you have any tips or solutions, please reply, thanks : ) DarkStone 2014-08-16
