External game controllers are not supported by iOS earlier versions but this restriction has been lifted with the release of iOS 7. Now iPhone supports external game controllers and there are many game controllers already available for Android and iOS. Adding to that, Now Logitech is preparing to launch Gamepad for iOS7 , still it is not officially launched but pictures of this gamepad already leaked online by evleaks in his twitter account.
the controller is quite lengthy unlike other game controllers out there.Navigation keypad located on left hand side of the controller whereas other keys are located on the right hand side of the controllers and iPhone is placed between these two.Still it is not sure whether its the final design of the Logitech gamepad since it is leaked one. Anyways we will soon find out when its launched officially.
