objective-c - 关于如何在 cocos2d 中制作排行榜和成就的任何教程

Question

我试过用谷歌搜索，但找不到看起来合法的。我已经设置了游戏中心，只需要设置排行榜和成就。任何建议都会很好。谢谢你。此外，由于我已将分数保存到字符串中，我是否可以将其放入排行榜中？

Answer 1

将排行榜代表添加到您的图层类。

@interface MyMainMenu : CCLayer<GKLeaderboardViewControllerDelegate>

根据您的需要显示排行榜。

-(void)displayLeaderboard
{
    GKLeaderboardViewController *leaderboardViewController = [[GKLeaderboardViewController alloc] init];
    leaderboardViewController.leaderboardDelegate = self;

    AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];

    [app.navController presentModalViewController:leaderboardViewController animated:YES];
}

添加这两个排行榜代表功能

#pragma mark GameKit delegate

-(void) achievementViewControllerDidFinish:(GKAchievementViewController *)viewController
{
    AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
    [app.navController dismissModalViewControllerAnimated:YES];
}

-(void) leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
    AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
    [app.navController dismissModalViewControllerAnimated:YES];
}

提交分数:

[[GameCenterManager sharedGameCenterObject] reportScore:score forCategory: kLeaderboardID];

使用 GKTapper 示例中的 GameCenterManager.m 类(请参阅您的 apple sdk 示例)。

这是从偏好中获取值的代码://从 pref 中获取保存的值

int highScore = [[[NSUserDefaults standardUserDefaults] objectForKey:@"HighScore"] intValue ];
