Well, to publish it yourself, you need to have a mac (since you have to use xcode). But, you can get a game published through akr, with this.

Also you'll probably need to buy the geplayer app, so you can test your game. So, if you do have a mac you can bypass those two things, but it technically is still possible to get your game on the appstore.
