iOS遊戲套件
IOS GameKit
簡介
GameKit是iOS SDK中常用的框架。其核心功能有3個:
- 互動遊戲平台Game Center,
- P2P裝置通訊功能
- In-Game Voice。
實例步驟
1.在連結iTunes 時請確保擁有一個唯一的App ID(unique App ID),App ID在我們應用程式更新bundle ID時及在Xcode程式碼簽名與對應的設定檔需要使用到。
2.建立新的應用程式和更新應用程式資訊。在新增的應用程式文件中可以了解更多有關資訊。
3.打開你申請的application,點擊Manage Game Center選項。進入後點選Enable Game Center使你的Game Center生效。接下來設定自己的Leaderboard和Achievements。
4.下一步涉及處理程式碼,並為我們的應用程式建立使用者介面。
5.建立一個single view application,並輸入 bundle identifier 。
6.更新ViewController.xib,如下圖
7.選擇專案文件,然後選擇目標,然後新增GameKit.framework
#8.為已新增的按鈕建立IBActions
9.更新ViewController.h文件,如下所示
#import <UIKit/UIKit.h>#import <GameKit/GameKit.h>@interface ViewController : UIViewController<GKLeaderboardViewControllerDelegate>-(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
輸出
運行該應用程序,輸出結果如下
#當我們點擊顯示排行榜時,螢幕顯示如下:
#當我們點擊更新分數,比分將被更新到我們排行榜上,我們會得到一個信息,如下圖所示
