I've integrated the Quiz plugin with Game Center and because I require a deployment target of iOS 6.0 I get the following warning about the 'authenticateWithCompletionHandler' being depreciated as of iOS 6.0: "authenticateWithCompletionHandler: is depreciated: first depreciated in iOS 6.0" Although it's only a warning and the Quiz can still submit scores to Game Center I would like to update this code function to be ready for iOS 7.x in case it stops working. Has anyone been able to recode the following section from 'GameCenterManager.m' file to the new format (I've tried based on Google searches but with no success): - (void) authenticateLocalUser { if([GKLocalPlayer localPlayer].authenticated == NO) { [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) { [self callDelegateOnMainThread: @selector(processGameCenterAuth:) withArg: NULL error: error]; }]; } } Thank you to anyone with assistance.

Sorry, Xcode actually calls it 'deprecated' (not depreciated).

Yeah you now have to present the GC login VC manually in iOS 6 instead of implicitly with that command. That's why it's deprecated. So you'll want to do something like this in your authentication method: localPlayer.authenticateHandler = ^(UIViewController *vc, NSError *error) { if(viewController) { [self presentViewController:vc];//present the login } else { // an error occurred } };

Ya, I found code similar to that as well but when I try you code snippet I get other warnings like "Instance method '-presentViewController:' not found (return type defaults to 'id')" for the 'presentViewController:vc' reference. I'll continue to play with it.

@WallE: Have you figured it out? Jake

Hi Jake, No. I found info on this subject on StackOverFlow but haven't been able to get it working correctly. It's no just a one line change like a lot of iOS deprecated code snippets. Kirk
