Ruby practical for OS X app / iOS app development?

I posted a similar query recently but for Android d开发者_Python百科evelopment where I was told Android development, while just about possible using Ruby, is far from ideal.

Now I was wondering is it any more practical / possible to use Ruby to develop iOS or OS X apps in one shape or form or will it just be a matter of mastering Ruby then using that as a basis for learning the more complex Objective-C language?

Try Rubymotion. It's far from free, but if you have U$200 to spare, it might be a good choice.
