IOS GameKit

簡介

GameKit是iOS SDK中一(yī)個常用的框架。其核心功能(néng)有3個：

交互遊戲平台Game Center，

P2P設備通(tōng)訊功能(néng)

In-Game Voice。

實例步驟

1.在鏈接 iTunes 時(shí)請(qǐng)确保擁有一(yī)個唯一(yī)的 App ID（ unique App ID），App ID在我們應用程序更新 bundle ID時(shí)及在Xcode代碼簽名與相應的配置文件需要(yào)使用到。

2.創建新的應用程序和(hé)更新應用程序信息。在添加新的應用程序文檔可(kě)以了(le)解更多有關信息。

3.打開(kāi)你申請(qǐng)的application,點擊Manage Game Center選項。進入後點擊Enable Game Center使你的Game Center生效。接下(xià)來設置自(zì)己的Leaderboard和(hé)Achievements。

4.下(xià)一(yī)步涉及處理代碼，并為(wèi)我們的應用程序創建用戶界面。

5.創建一(yī)個single view application，并輸入 bundle identifier 。

6.更新 ViewController.xib。

7.選擇項目文件，然後選擇目标，然後添加GameKit.framework

8.為(wèi)已添加的按鈕創建IBActions

9.更新ViewController.h文件，如(rú)下(xià)所示

#import

#import

@interface ViewController : UIViewController

-(IBAction)updateScore:(id)sender;

-(IBAction)showLeaderBoard:(id)sender;

@end

10.更新ViewController.m ，如(rú)下(xià)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
