iOS Development: Strange problem with authenticating Game Center user
I'm building an iPhone game that supports Game Center (GC). When the app launches, I try to authenticate the local player...
if([GKLocalPlayer localPlayer].authenticated == NO)
{
[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error)
{
[self callDelegateOnMainThread: @selector(processGameCenterAuth:) withArg: NULL error: error];
}];
}
Everything seemed to be working well. If the user wasn't signed into GC when the app launched, the app would display a dialog box giving them three options...
- Sign into existing account
- Create an account
- Cancel
This is the desired behavior, but while I was testing, I clicked the "Cancel" option and now the authentication process errors out every time with the following error "The requested operation has been cancelled." Even when I delete the app and reinstall it, it still errors out and that dialog box never pops ups now.开发者_StackOverflow社区
Does anyone know why this is happening or how I can fix it?
Thanks in advance for your wisdom!
It turns out that is apple undocumented behavior.
After 3 times a user press cancel in a row, he has to go to the Game Center app and connect from there.
Go Figure.
