What languages besides Objective-C will generate application code that works on an iPad?

I would like to write an app for the iPad but I can't stand Objective-C.

Is there a language generator that would spit out Objective-C but let me write my iPad application in another language?

I've heard a little about MacRuby and am curious whether it coul开发者_开发百科d be used this way. Any other similar projects in other languages?

C# with MonoTouch.
JavaScript with Appcelerator Titanium.
Flex with ELIPS Studio 3.
Python with PyObjC (for jailbroken iPhones though).

Apparently Lua is an option.

John McIntosh uses Smalltalk on the iPhone. For instance, his Mobile Wiki Server app.

No computer anywhere (well maybe some) cares what language you write your programs in. Heck, you could hand-write machine instructions if you were patient (and crazy) enough. As long as you can figure out how to interact properly with the system call interface and the ABI, you can do whatever you want.

You could use Corona, Torque, or Unity. These all have advantages and disadvantages compared to using the standard Objective-C SDK, but really, if it's about the language itself, it's hard to see how you would be better able to "stand" the languages supported by these three than Objective-C.
