game-center

问题 I'm getting results to show in the leaderboard in sandbox mode, but I expected each result to appear. Only one result is showing. Is that normal? The sort option to sort from highest to lowest seems to imply multiple results should show up. What does show up is my high score, which does update if the score is surpassed. Only one result shows whether I present a VC thus: - (void) presentLeaderboards { GKGameCenterViewController* gameCenterController = [[GKGameCenterViewController alloc] init];

问题 My game currently has four leaderboards for differently difficulties, however this is going to change in a new update. I no longer want to make use of all of these, but only one. How can I setup the new version to only use this new leaderboard and have the other hidden so they can't be seen by the user? Thanks. 回答1: According to iTunes Connect: Once a leaderboard has gone live for any version of your app, it cannot be removed. 回答2: You may update your game without having any pointers to the

问题 [GKMatchmaker sharedMatchmaker].inviteHandler is deprecated in iOS 7, yet the GameKit guides still say to set it up that way. Does anyone know what we're supposed to be using for iOS 7 real time game invites? There are new classes / methods for several listener classes, but none address this specifically that I have seen. 'inviteHandler' is deprecated: first deprecated in iOS 7.0 回答1: It looks like the intended replacement is the GKInviteEventListener protocol. You can see a reference to it

问题 I am trying to implement a turn-based app, and there is no problem with sending turn data, but I see no way of receiving data automatically. So far, I have found out that much: There is a GKTurnBasedEventHandlerDelegate -protocol. It is easy to implement, but where do I set that object to be a delegate of whatever it has to be a delegate of? It does not seem to be a delegate of GKTurnBasedMatch , or GKTurnBasedMatchmakerViewController , or GKMatchMaker . There is also a method of

问题 I am working on a multiplayer game through game center and I am having one problem. When I try to invite one of my friends I get failed status.

问题 So I was wondering after reading the apple docs(https://developer.apple.com/library/ios/documentation/GameKit/Reference/GKLeaderboard_Ref/Reference/Reference.html#//apple_ref/occ/instp/GKLeaderboard/category) how would one create a UITableView and fill it with the localPlayers Game Center friends and there scores in a specific leaderboard. I know how to get the friends list and friends scores individually by using the loadScoresWithCompletionHandler: method. Edit: So far I got this to get

问题 I am new to Swift and am having trouble adding a Game Center leaderboard into my Sprite Kit game. I created a button for the leaderboard but it is in an SKScene and it seems that the code for Game Center needs to be inside a View Controller?

Again, I am very new to this and completely lost -- any help would be greatly appreciated. 回答1: you could create a cocoa touch class with the UIViewController Subclass
