Game Center Warning: Attempt to present <GKHostedAuthenticateViewController>

    Running Unity 4.6.8p8
    Reproduced in iOS 8.3 & 9.0

    Warning: Attempt to present <GKHostedAuthenticateViewController: 0x16ee8e50> on <UnityDefaultViewController: 0x180849f0> which is already presenting <GKHostedAuthenticateViewController: 0x1817e5f0>

    Steps to Reproduce:
    1) Make call to Social.localUser.Authenticate()
    2) Once the Game Center login screen is displaying, hit the home button.
    3) Bring the app to the foreground by tapping the icon on the home screen.
    4) The warning will come up in xcode logs.

    After this happens, the Game Center login screen will not go away. If you hit cancel or login, the screen just stays in the foreground.

    We are not calling Social.localUser.Authenticate() a 2nd time.

    This happens in an empty project with 1 sprite and 1 UI Canvas and no 3rd party plugins as well as in our actual project of course. On 4.6.5(not sure what patch) the game would just crash. I decided to update to see if the behavior changed, and it did, but it is not fixed.

    Is there a work around for this? Any suggestions?

    Hi,

    I tried to reproduce your issue in various ways with 4.6.8p3, 4.6.8p4 and 4.6.9f1. Everytime GC worked without issues. Maybe there is something else I am missing?

    Currently, I have the same issue. We are on Unity 5.2.2f1 and Xcode 7.2.
    I press the home button before the GC popup opens or while the popup is opening. If I open the app again, it always throws the warning mentioned in the first post, or worst the app crashes.

    By the way I can't find the bug report on the issue tracker website using the issue id 739670. Is there way to find it?
