 To offer a proper experience with GameKit view controllers, a UIViewController

 based OpenGL should be used. For an example please look at the OpenGL ES Application based 

 template in the new project menu. 

 If the game view does not autorotate during gameplay, please create a new UIViewController that does 

 autorotate and present the modal view controller from that. To control where the welcome 

 banners slide in from you must set the position of the status bar on rotation. You should do 

 this even if the status bar is hidden, to make sure banners and alerts appear oriented correctly.

{

 // Return YES for supported orientations

 return (interfaceOrientation == UIInterfaceOrientationPortrait);
