Developign x-platform mobile apps on ubuntu

I'm a junior iphone developer and got familiar with developing on xcode on top of Mac OS. I wanna build some Cross-Platform apps in the near future and wanna Use Ubuntu as my Operating system. I found many solutions开发者_运维知识库 that run only on Mac OS or need mac to build apps for iphone but this is not what i need . i need something which can keep me far from mac (for some reasons). I heard about AIR packager for iOS and that also AIR does apps for android but i'm not a flash guy (but can learn if it will do the job), so i wanna guidance from experience people like you about what is the suitable route should I take.

Thanks in advance

I think you may want to build web apps instead. They are written in JavaScript, HTML and CSS. There are some frameworks out there, e.g. Unify. That one is using PhoneGap, so you are able to use native functionality in your web app, too. It might still be required to have a Mac to build the iOS package, but apart from that this would be the way to go.
