Mobile/IOS app in Flex Builder 3?

is it 开发者_高级运维possible to publish a mobile (specifically IOS) app using Flex Builder 3, or is this only available on Flash Builder 4.5 and later?

Mobile support is only available in Flash Builder 4.5 and later. You can use the free command line tools to create mobile applications; but I strongly recommend that you upgrade your tooling because it will save you a lot of headaches.

Although it is possible, I am not sure I would recommend trying to publish a Flex 3 based app to iOS or any mobile platform. Rewriting the app to use Spark components is going to give a much more optimized performance.
