How do I enable the GameCenter for my app? Because you wrote that you have to create an app to enable the gamecenter. But if you create the app on Itunes connect, isn't it already posted into Itunes Store? Isn't it possible to enable game center while developing the game?
Create the app in iTunes connect and then enable gamecenter from the control panel.
Thanks. I am just afraid of creating the app in itunes connect, because it seems that it is going to be posted to the appstore. I mean you even have to select the pricing..?
It can not be submitted until you have uploaded the code for your Application/Game. So it will just sit there and let you set everything up until you add the code and submit it for review.
