There are two basic varieties of LiveCycle XFA...Static XFA and Dynamic XFA, which are very different in terms of their future for potential support in Adobe Reader for iOS. Which variety of XFA are you using?
Static XFA uses the PDF markup language for content and form fields, so users can view the documents in Adobe Reader for iOS, but we currently do not properly handle filling, saving, and submitting those forms. I have improving our handling of Static XFA on my roadmap, but cannot offer any specific date yet (sorry, policy plus actual uncertainty). I know that there are some other apps that partially support Static XFA, though I do not know how complete their support is. If you can even open the XFA document in Adobe Reader for iOS, it is likely Static XFA.
Dynamic pdf forms on mobile devices are exactly what our customers need in their current projects . Unfortunately, more and more company turn away form PDF and Adobe because the xfa technology is not supported by mobile reader. I can not understand why adobe is not serving this market?Jan
btw: Why is static XFA supported by PDF Expert but not by Adobe mobile Reader?
I've written a blog post to describe our approach around XFA forms and mobile devices.
I hope that helps to clarify things and our approach.
BTW we looked at supporting just static XFA on Adobe Reader mobile but felt that delivering half the solution wasn't good enough (there are limits to how much of the scripting model can be supported with static and dynamic XFA isn't an option).
