在程序中添加Game Center功能
来源：互联网 发布：京津冀 知乎 编辑：程序博客网 时间：2024/05/16 01:57
步骤：1.在iTunes Connect中启用Game Center。2.配置程序的Bundle identifier3.导入Game Kit Framework4.导入头文件<GameKit/GameKit.h>5.检测当前设备是否支持Game Center6.对于不支持Game Center的设备，对Game Kit Framework的引用应改为‘弱引用’（weak link）。7.程序启动后，认证用户。 四、认证用户用户必须具有账户才可以访问Game center。程序启动或在需要调用Game Center功能的地方，认证当前的使用账户。 五、排行榜功能5.1 在iTunes Connect中配置排行榜（得分格式、排行榜分类）等5.2 将得分发送到Game Center- (void) reportScore: (int64_t) score forCategory: (NSString*) category {GKScore *scoreReporter = [[[GKScore alloc] initWithCategory:category] autorelease]; scoreReporter.value = score;[scoreReporter reportScoreWithCompletionHandler: ^(NSError *error) { if(error != nil) { //处理储物 } else { //显示排行榜 } }];} 5.3 显示排行榜（LeaderboardController）- (void) showLeaderboard{GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init]; 在显示leaderboard之前，可以配置leaderboard view Controller的一些属性。（category 属性，配置显示哪中分类下的排行榜；timeScope属性，配置显示哪个时间段内的排行榜) //响应用户关闭排行榜的事件： 5.4 获取排行榜数据，自定义排行榜显示的view 6.1 方式1 （直接获取数据、自定义排行榜的view） 6。2 0.99.5 sdk of cocos2d have a RootViewController 6.3 方式3 使用viewcontroller创建一个viewcontroller 将其view属性添加到cocos2d的 glview UIViewController *tempVC=[[UIViewController alloc] init]; GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease]; request.minPlayers = 2;request.maxPlayers = 2; request.playersToInvite = playersToInvite; GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease]; mmvc.matchmakerDelegate = self; [[[CCDirector sharedDirector] openGLView] addSubview:tempVC.view]; [tempVC presentModalViewController:mmvc animated:YES]; //响应事件 -(void)matchmakerViewControllerWasCancelled:(GKMatchmakerViewController *)viewController { [tempVC dismissModalViewControllerAnimated:YES];[tempVC.view removeFromSuperview];} { [super onExit]; [tempVC release]; } - (void) showLeaderboard{GKLeaderboardViewController *leaderboardController = [[[GKLeaderboardViewController alloc] init] autorelease]; if (leaderboardController != nil) {leaderboardController.leaderboardDelegate = self; [[[CCDirector sharedDirector] openGLView] addSubview:tempVC.view]; [tempVC presentModalViewController:leaderboardController animated: YES]; } } { [tempVC dismissModalViewControllerAnimated:YES]; [tempVC.view removeFromSuperview]; } /* Erica Sadun, http://ericasadun.com iPhone Developer’s Cookbook, 3.0 Edition BSD License, Use at your own risk */ // Thanks to Emanuele Vulcano, Kevin Ballard/Eridius, Ryandjohnson, Matt Brown, etc. #include <sys/socket.h> // Per msqr #include <sys/sysctl.h> #include <net/if.h> #include <net/if_dl.h> #import “UIDevice-Hardware.h” @implementation UIDevice (Hardware) /* Platforms iFPGA -> ??

一、iTunes Connect的配置 iTunes Connect Developer Guide https://itunesconnect.apple.com/docs/iTunesConnect_DeveloperGuide.pdf/
二、配置程序的Bundle identifier
com.myCompany.myCoolGame 与 iTunes Connect中配置相同
三、添加FrameWork （weak－link）检测当前设备是否支持Game Center
Target->’Get info’ ->’Genaral’ Linkd libray -> 将Required改为Weak
BOOL isGameCenterAvailable(){
// Check for presence of GKLocalPlayer API. Class gcClass = (NSClassFromString(@”GKLocalPlayer”));// The device must be running running iOS 4.1 or later.
NSString *reqSysVer = @”4.1″; NSString *currSysVer = [[UIDevice currentDevice] systemVersion]; BOOL osVersionSupported = ([currSysVer compare:reqSysVeroptions:NSNumericSearch] != NSOrderedAscending);
return (gcClass && osVersionSupported);}
- (void) authenticateLocalUser{if([GKLocalPlayer localPlayer].authenticated == NO){ [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) { if(error == nil) { //认证成功 } else { //失败UIAlertView* alert= [[[UIAlertView alloc] initWithTitle: @”Game Center Account Required” message: [NSString stringWithFormat: @"Reason: %@", [error localizedDescription]] delegate: self cancelButtonTitle: @”Try Again…” otherButtonTitles: NULL] autorelease]; [alert show]; } } ];}}
if (leaderboardController != nil) {leaderboardController.leaderboardDelegate = self; [self presentModalViewController: leaderboardController animated: YES];}}
-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController {[self dismissModalViewControllerAnimated:YES]; }
//获取所有用户- (void) retrieveTopTenScores{ GKLeaderboard *leaderboardRequest = [GKLeaderboard alloc] init]; if (leaderboardRequest != nil) {leaderboardRequest.playerScope = GKLeaderboardPlayerScopeGlobal; leaderboardRequest.timeScope = GKLeaderboardTimeScopeAllTime; leaderboardRequest.range = NSMakeRange(1,10); [leaderboardRequest loadScoresWithCompletionHandler: ^(NSArray *scores, NSError *error) { if (error != nil) // handle the error. if (scores != nil) // process the score information.}];}
//获取特定用户的排行榜数据- (void) receiveMatchBestScores: (GKMatch*) match{GKLeaderboard *query = [GKLeaderboard alloc] initWithPlayers: match.players]; if (query != nil) {[query loadScoresWithCompletionHandler: ^(NSArray *scores, NSError *error) {}if (error != nil) // handle the error.if (scores != nil) // process the score information.}];}
六、Cocos2d 中加入 Game Center
//退出时-(void) onExit
- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController获取iphone、ipad、ipod具体版本信息
