IOS 7排行榜中的游戏中心

设置排行榜转到iTunes Connect>管理您的应用>您的应用>管理游戏中心>添加排行榜>单个排行榜。

To set up a leaderboard go to iTunes Connect > Manage Your Apps > Your App > Manage Game Center > Add Leaderboard > Single Leaderboard.

为您的排行榜命名并提供所需的全部信息需要组织信息。

Give your leaderboard a name and all of the required organizational information needed.

将此方法添加到 GCHelper.m ：

-(void) submitScore:(int64_t)score Leaderboard: (NSString*)leaderboard
{

    //1: Check if Game Center
    //   features are enabled
    if (!_gameCenterFeaturesEnabled) {
        return;
    }

    //2: Create a GKScore object
    GKScore* gkScore =
    [[GKScore alloc]
     initWithLeaderboardIdentifier:leaderboard];

    //3: Set the score value
    gkScore.value = score;

    //4: Send the score to Game Center
    [gkScore reportScoreWithCompletionHandler:
     ^(NSError* error) {

         [self setLastError:error];

         BOOL success = (error == nil);

         if ([_delegate
              respondsToSelector:
              @selector(onScoresSubmitted:)]) {

             [_delegate onScoresSubmitted:success];
         }
     }];


}

并将此添加到您的 GCHelper.h ：

-(void) submitScore:(int64_t)score Leaderboard: (NSString*)leaderboard;

现在在游戏的.m中将此方法添加到游戏结束时调用的任何方法：

Now in the .m for your game add this method to whatever method you call when the game is over:

[[GCHelper sharedGameKitHelper] submitScore:highScore Leaderboard:LeaderboardName];

在此示例中 highScore 是 int_64 您的分数值和 LeaderboardName 是一个 NSString 等于您在iTunes Connect中设置的排行榜标识符。还要确保为您的应用程序添加Game Center功能。

In this example highScore is the int_64 value of your score and LeaderboardName is an NSString equal to the Leaderboard Identifier you set up in iTunes Connect. Also be sure to add Game Center capabilities to your application.

之后您应该能够提交高分！

After that you should be able to submit high scores!

还添加到GCHelper.m

ALSO ADD THIS TO GCHelper.m

-(void) setLastError:(NSError*)error {
    _lastError = [error copy];
    if (_lastError) {
        NSLog(@"GameKitHelper ERROR: %@", [[_lastError userInfo]
                                           description]);
    }
}

并将其添加到GCHelper.h

AND ALSO ADD THIS TO GCHelper.h

@property (nonatomic, assign)id<GCHelperProtocol> delegate;

这是我的GCHelper.h：

Here is my GCHelper.h:

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

//   Include the GameKit framework
#import <GameKit/GameKit.h>

//   Protocol to notify external
//   objects when Game Center events occur or
//   when Game Center async tasks are completed
@protocol GCHelperProtocol<NSObject>


-(void) onScoresSubmitted:(bool)success;


@end


@interface GCHelper : NSObject

@property (nonatomic, assign)id<GCHelperProtocol> delegate;

// This property holds the last known error
// that occured while using the Game Center API's
@property (nonatomic, readonly) NSError* lastError;

+ (id) sharedGameKitHelper;

// Player authentication, info
-(void) authenticateLocalPlayer;

//Scores
-(void) submitScore:(int64_t)score Leaderboard: (NSString*)leaderboard;
