There are a number of ways you can get *nearly* there with iOS development on Windows. You WILL, however, need a genuine Macintosh meeting the requirements of Apple, and also an Apple developer's license subscription to get your app on an actual device and into the app store.
* Unity (Free/Premium)
* MonoGame (Free)
* MonoTouch (Premium)
* GameMaker Studio (Premium)
I'm sure there are many more, but these are just the ones I've heard of.
