Apple PDF viewers barely work with regular Acroforms and don't work with XFA forms created in LiveCycle Designer. Even the mobile versions of Adobe Reader don't work with XFA: Adobe Reader Mobile and XFA forms from LiveCycle Designer | Adobe LiveCycle Blog .

I'll try to see if I can find something better. Stay tuned...
