Question

我正在尝试在我的代码中实现GKChallengeListener，并且我使用了Apple的GameCenterManager类。玩家认证很好，排行榜和挑战也是如此。 But i want to notify my application when the remote player completed the challenge. for this i have used GKChallengeListener protocols. but they are not calling up when i am sending or receiving the challenges引用。但是我知道哪个班级会把德尔盖特称为自己 https://developer.apple.com/library/ios/documentation/GameKit/Reference/GKEventListener_Ref/Reference/Reference.html#//apple_ref/occ/intf/GKChallengeListener

在ViewController.h中

@interface ViewController : UIViewController <UIActionSheetDelegate, GameCenterManagerDelegate,GKGameCenterControllerDelegate,GKChallengeListener> {
    GameCenterManager *gameCenterManager;
    NSInteger  currentScore;
    NSString* currentLeaderBoard;
    IBOutlet UILabel *currentScoreLabel;
}
@property (nonatomic, retain) GameCenterManager *gameCenterManager;
@property (nonatomic, assign) NSInteger currentScore;
@property (nonatomic, retain) NSString* currentLeaderBoard;
@property (nonatomic, retain) UILabel *currentScoreLabel;
- (IBAction) showLeaderboard;
- (IBAction) increaseScore;

@end

在ViewController.m中

@implementation ViewController

@synthesize gameCenterManager;
@synthesize currentScore;
@synthesize currentLeaderBoard;
@synthesize currentScoreLabel;

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.currentLeaderBoard = kLeaderboardID;
    self.currentScore = 0;
    if ([GameCenterManager isGameCenterAvailable]) {
        self.gameCenterManager = [[GameCenterManager alloc] init];
        [self.gameCenterManager setDelegate:self];
        [self.gameCenterManager authenticateLocalUser];
    } else {
        // The current device does not support Game Center.
    }
}

-(void)player:(GKPlayer *)player issuedChallengeWasCompleted:(GKChallenge *)challenge byFriend:(GKPlayer *)friendPlayer{
    NSLog(@"issued challenge was completed by friend");

}
-(void)player:(GKPlayer *)player didCompleteChallenge:(GKChallenge *)challenge issuedByFriend:(GKPlayer *)friendPlayer{
    NSLog(@"player did complete challenge");
}
-(void)player:(GKPlayer *)player didReceiveChallenge:(GKChallenge *)challenge{
    NSLog(@"player did recieve challenge");
}
-(void)player:(GKPlayer *)player wantsToPlayChallenge:(GKChallenge *)challenge{
    NSLog(@"player wants to play challenge ");
}

这在iOS 7.0中已弃用，但您仍可以将其用作替代

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.currentLeaderBoard = kLeaderboardID;
    self.currentScore = 0;
    if ([GameCenterManager isGameCenterAvailable]) {

        self.gameCenterManager = [[GameCenterManager alloc] init];
        [self.gameCenterManager setDelegate:self];
        [self.gameCenterManager authenticateLocalUser];
    } else {
        // The current device does not support Game Center.
    }
GKChallengeEventHandler
    *gk
    =[GKChallengeEventHandler challengeEventHandler].delegate=self;
}

- (void)localPlayerDidCompleteChallenge:(GKChallenge *)challenge
{
    NSLog(@"localPlayerDidCompleteChallenge");
}
- (void)localPlayerDidReceiveChallenge:(GKChallenge *)challenge
{
    NSLog(@"localPlayerDidReceiveChallenge");
}
- (void)localPlayerDidSelectChallenge:(GKChallenge *)challenge{
    NSLog(@"localPlayerDidSelectChallenge");
}
- (void)remotePlayerDidCompleteChallenge:(GKChallenge *)challenge{
    NSLog(@"remotePlayerDidCompleteChallenge");
}
- (BOOL)shouldShowBannerForLocallyCompletedChallenge:(GKChallenge *)challenge
{
    return YES;
}
- (BOOL)shouldShowBannerForLocallyReceivedChallenge:(GKChallenge *)challenge
{
    return YES;
}
- (BOOL)shouldShowBannerForRemotelyCompletedChallenge:(GKChallenge *)challenge
{
    return YES;
}

今天我自己挣扎了一下。

技巧是将实现GKLocalPlayerListener协议的对象注册为localPlayer的侦听器。呃......那句话好像已经回归了，但这可能会有所帮助。

/* this happens inside my authenticateLocalPlayer method */
if ([GKLocalPlayer localPlayer].authenticated) {
    [[GKLocalPlayer localPlayer] registerListener:self];
    // More stuff here
    }

然后在同一个对象中实现协议方法。

编辑：哦！而且你不应该实现GKChallengeListener。您应该只实现GKLocalPlayerListener。（我打算发布一个链接，但如果我现在可以找到它，那就很危险。）

希望有所帮助。

哪个类用于实现GKLocalPlayerListener协议
