IOS GameKit 简介 GameKit是iOS SDK中一个常用的框架。其核心功能有3个: ?交互游戏平台Game Center, ?P2P设备通讯功能 ?In-Game Voice。 实例步骤 1.在链接 iTunes 时请确保拥有一个一的 App ID( unique App ID),App ID在我们应用程序更新 bundle ID时及在Xcode代码签名与相应的配置文件需要使用到。 2.创建新的应用程序和更新应用程序信息。在添加新的应用程序文档可以了解更多有关信息。 3.打开你申请的application,点击Manage Game Center选项。进入后点击Enable Game Center使你的Game Center生效。接下来设置自己的Leaderboard和Achievements。 4.下一步涉及处理代码,并为我们的应用程序创建用户界面。 5.创建一个single view application,并输入 bundle identifier 。 6.更新 ViewController.xib,如下所示 7.选择项目文件,然后选择目标,然后添加GameKit.framework 8.为已添加的按钮创建IBActions 9.更新ViewController.h文件,如下所示 #import #import @interface ViewController : UIViewController -(IBAction)updateScore:(id)sender; -(IBAction)showLeaderBoard:(id)sender ;@end 10.更新ViewController.m ,如下所示 #import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; if([GKLocalPlayer localPlayer].authenticated == NO) { [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) { NSLog(@"Error%@",error); }]; } } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. }- (void) updateScore: (int64_t) score forLeaderboardID: (NSString*) category { GKScore *scoreObj = [[GKScore alloc] initWithCategory:category]; scoreObj.value = score; scoreObj.context = 0; [scoreObj reportScoreWithCompletionHandler:^(NSError *error) { // Completion code can be added here UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"Score Updated Succesfully" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles: nil]; [alert show]; }]; } -(IBAction)updateScore:(id)sender{ [self updateScore:200 forLeaderboardID:@"tutorialsPoint"]; } -(IBAction)showLeaderBoard:(id)sender{ GKLeaderboardViewController *leaderboardViewController = [[GKLeaderboardViewController alloc] init]; leaderboardViewController.leaderboardDelegate = self; [self presentModalViewController: leaderboardViewController animated:YES]; } #pragma mark - Gamekit delegates - (void)leaderboardViewControllerDidFinish: (GKLeaderboardViewController *)viewController{ [self dismissModalViewControllerAnimated:YES]; } @end 输出 运行该应用程序,输出结果如下 当我们单击显示排行榜时,屏幕显示如下: 当我们点击更新分数,比分将被更新到我们排行**,我们会得到一个信息,如下图所示 学习链接/ios/?tg=5009295340 学习交流群:317140762
