Unity3.5之后，原生支持GameCenter，大部分方法都是封装好的， 我参考了别人的代码和官方手册，做了下面的Demo， 使用的时候调用GameCenterManager.GetInstance().Start()
Tips: Editor-Project Settings-Player, 设置Bundle Identifier为自己应用的Bundle Id（不懂的自行Google）
using UnityEngine; using UnityEngine.SocialPlatforms; using UnityEngine.SocialPlatforms.GameCenter; public class GameCenterManager : System.Object { private static GameCenterManager instance; private static object _lock=new object(); private GameCenterManager(){} public static GameCenterManager GetInstance() { if(instance==null) { lock(_lock) { if(instance==null) { instance=new GameCenterManager(); } } } return instance; } public void Start() { Social.localUser.Authenticate(HandleAuthenticated); } private void HandleAuthenticated(bool success) { Debug.Log("*** HandleAuthenticated: success = " + success); if(success) { //下面三行看个人需要，需要什么信息就取什么信息，这里注释掉是因为担心有的朋友没有在iTunesConnect里设置排行、成就之类的东西，运行起来可能会报错 //Social.localUser.LoadFriends(HandleFriendsLoaded); //Social.LoadAchievements(HandleAchievementsLoaded); //Social.LoadAchievementDescriptions(HandleAchievementDescriptionsLoaded); } } private void HandleFriendsLoaded(bool success) { Debug.Log("*** HandleFriendsLoaded: success = " + success); foreach(IUserProfile friend in Social.localUser.friends) { Debug.Log("* friend = " + friend.ToString()); } } private void HandleAchievementsLoaded(IAchievement[] achievements) { Debug.Log("* HandleAchievementsLoaded"); foreach(IAchievement achievement in achievements) { Debug.Log("* achievement = " + achievement.ToString()); } } private void HandleAchievementDescriptionsLoaded(IAchievementDescription[] achievementDescriptions) { Debug.Log("*** HandleAchievementDescriptionsLoaded"); foreach(IAchievementDescription achievementDescription in achievementDescriptions) { Debug.Log("* achievementDescription = " + achievementDescription.ToString()); } } // achievements public void ReportProgress(string achievementId, double progress) { if (Social.localUser.authenticated) { Social.ReportProgress(achievementId, progress, HandleProgressReported); } } private void HandleProgressReported(bool success) { Debug.Log("*** HandleProgressReported: success = " + success); } public void ShowAchievements() { if (Social.localUser.authenticated) { Social.ShowAchievementsUI(); } } // leaderboard public void ReportScore(string leaderboardId, long score) { if (Social.localUser.authenticated) { Social.ReportScore(score, leaderboardId, HandleScoreReported); } } public void HandleScoreReported(bool success) { Debug.Log("*** HandleScoreReported: success = " + success); } public void ShowLeaderboard() { if (Social.localUser.authenticated) { Social.ShowLeaderboardUI(); } } }
