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 时请确保拥有一个唯一的 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

gamekitInterface

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
