When an iPhone app with GameKit launches, and the device is already logged in to GameCenter, a small message slides in on top of the screen, saying something along the lines of "Welcome back %username!". What I found out is the following: that message appears in its own UIWindow that eventually slides the message away and releases itsel...

Because my game can run on iOS versions back to 3.0, I want to have it fallback to just saving achievements and leaderboards locally in the absence of Game Center.

It looks to me like Apple was in a bit of a hurry to implement GameCenter. Maybe I am overlooking something. If you create a game where you want to offer in-app purchases (say you want to sell additional maps or add ons), is there any way at all to match players who share the same maps (plural) using GKMatchRequest? i.e. whose in-app pu...

It could be that recent revisions to GameKit are simply a tech demo for blocks. Or, that the "on return" functionality of certain GameKit APIs is just too inconsequential to deserve a dedicated delegate class, and blocks now fulfill the function of an informal protocol. Though it feels like a subjective question, perhaps there is a defi...
What would you do in the following scenario: When implementing a multiplayer game, you use GKMatchmaker to find players. When the required number of players has connected, you start the match. Now one of the players receives an incoming call. What now? If the user takes the call, the application will move to the background, the conne...
Apple states that if you want to report a GKAchievement but you get a network error, the best way to handle this is to save the GKAchievement (possibly adding it to an array), then periodically attempt to report the achievement. What is the best place to save the achievements? Would NSUserDefaults suffice, or would a property list be a ...

The Game Center documentation indicates that the playersToInvite parameter is non-nil when your application is launched directly from the Game Center application to host a match.

As I understand it, they're two separate user acc...
