Can someone post a proper Ubuntu Configuration for developing iPad's applications?
I need a good IDE and a guide on how to install any essential compilers etc.
Developing Iphone and IPad applications is supported only if it is developed on a Mac. This is especially true if you want your application to end up in the App-store. A good explanation is given on another stackoverflow site here which ties together your Objective-C question and writing for the IPad.
Apple, unusually perhaps, have an excellent IDE and development tools which they give away for free.
I would either buy a used Mac, or (if you have a license) - install a virtualised OS-X in VMWare etc.
I do agree with @fossfreedom . The only application I know is dragonFireSDK , to create iPad and iPhone applications in Windows only.
I also asked for alternative in Ubuntuforums.org long time ago, but I didn't find anything.
