While there are a handful of gaming controllers out there in the market that will play nice with Apple’s iOS products, not every game is created equal, meaning that one controller does not necessarily fit all. Given Apple’s tendency to unify everything, we wouldn’t be surprised if the Cupertino company might be interested in providing a reference design for third-party manufacturers to help create some sort of standard gaming hardware, and thanks to a sighting by the folks at Touch Arcade, they have spotted a guide on Apple’s developer site that provides developers a basic guideline on how game controllers should be used in conjunction with iOS devices.
It is possible that the images above are just examples rather than actual designs that Apple plans to introduce to third-party manufacturers, but it does suggest different types of controllers. One of which will attach to iOS devices like the iPhone or iPod touch, ultimately transforming the device into a mobile gaming console like the Nintendo 3DS or the PS Vita. The other drawing shows off a more traditional controller which we’re guessing will pair via Bluetooth. We’re not sure what will become of this, but do stay tuned for more info.
