不在游戏中心提交分数

Question

我想在我的应用程序中输入游戏中心 所以我创建了新项目“gamecenter”来测试游戏中心 我引用了“http://www.youtube.com/watch?v=9avpP0hYwik”视频。但 我使用 xcode 4.2，所以删除“autorelease”
应用程序未在 gamecenterhelp 上提交分数 :-( 我的代码是

viewController.h

 #import <UIKit/UIKit.h>

@interface ViewController : UIViewController
{
    IBOutlet UILabel *scoreText;
    int *scoreInt;
}

-(IBAction)subScore:(id)sender;
-(IBAction)showLeader:(id)sender;
-(IBAction)addScore:(id)sender;

@end

ViewController.m

#import "ViewController.h"
#import <Gamekit/Gamekit.h>


@implementation ViewController

-(IBAction)subScore:(id)sender
{
    GKScore *scoreReporter = [[GKScore alloc] initWithCategory:@"1234567"];
    scoreReporter.value = scoreInt;

    [scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
        if (error != nil)
        {
            NSLog(@"failed");
        }
        else
        {
            NSLog(@"Succeeded");
        }
    }];
}
-(IBAction)showLeader:(id)sender
{
    GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
    if (leaderboardController != nil) 
    {
        leaderboardController.leaderboardDelegate = self;
        [self presentModalViewController:leaderboardController animated:YES];
    }
}

-(void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
    [self dismissModalViewControllerAnimated:YES];
}

-(IBAction)addScore:(id)sender
{
    scoreInt +=1;
    NSString *clicks = [NSString stringWithFormat:@"%d", scoreInt];
    scoreText.text = clicks;
}

        {
            NSLog(@"Authentication Successful!");

    }];

您确定您的排行榜类别 ID 正确吗？

您在请求块中收到任何错误消息吗？

如果您的异步请求块没有得到响应，则意味着游戏中心尚未准备好处理您的请求。如果您刚刚创建排行榜，则需要等待几个小时。
