加载游戏中心的朋友和他们的分数到UITableView

所以我想知道阅读苹果文档（ https://developer.apple.com/library/ios/documentation/GameKit/Reference/GKLeaderboard_Ref/Reference/Reference.html#//apple_ref/occ/instp/GKLeaderboard/category ）如何创build一个UITableView并将其填充到localPlayers Game Center的朋友，并在特定的排行榜上得分。 我知道如何通过使用loadScoresWithCompletionHandler：方法来获取朋友列表和朋友分数。

编辑：到目前为止，我得到这个个人朋友的照片，得分和显示名保存到一个NSArray。 但我无法弄清楚如何在UITableView显示它们。

- (void) loadPlayerData: (NSArray *) identifiers { GKLeaderboard *leaderboardRequest = [[GKLeaderboard alloc] init]; if (leaderboardRequest != nil) { leaderboardRequest.playerScope = GKLeaderboardPlayerScopeFriendsOnly; leaderboardRequest.timeScope = GKLeaderboardTimeScopeAllTime; leaderboardRequest.category = @"MJ_IL"; [leaderboardRequest loadScoresWithCompletionHandler: ^(NSArray *scores, NSError *error) { if (error != nil) { // handle the error. if (scores != nil) } if (scores != nil){ for (GKScore* score in scores) { NSArray *playerIdArray = [NSArray arrayWithObject:score.playerID]; [GKPlayer loadPlayersForIdentifiers:playerIdArray withCompletionHandler:^(NSArray *players, NSError *error) { GKPlayer *player = [players objectAtIndex:0]; [player loadPhotoForSize:GKPhotoSizeSmall withCompletionHandler:^(UIImage *photo, NSError *error) { if (score.playerID == player.playerID) { if (photo != nil) { playerInfo = [NSArray arrayWithObjects:score, player.displayName, photo, nil]; } else if (photo == nil) { playerInfo = [NSArray arrayWithObjects:score, player.displayName, nil]; } if (error != nil) { NSLog(@"%@", error.localizedDescription); } } }]; }]; } } }]; } } - (void)compareLocalPlayerScoreWithFriends { GKScore *friendScore = [playerInfo objectAtIndex:0]; NSString *friendDisplayName = [playerInfo objectAtIndex:1]; if ([playerInfo objectAtIndex:2] != nil) { UIImage *friendPhoto = [playerInfo objectAtIndex:2]; if (friendScore.value > interactiveHighscore) { [friendNameLabel setText:friendDisplayName]; [friendScoreLabel setText:(NSString *)friendScore]; friendImageView.image = friendPhoto; } } } 

谢谢你们，乔治

看一下Ray Wenderlich的这个教程 ，它解释了如何在UITableView显示简单的图片和文本 – 有三个部分，至less应该让你使用一个基本的工作视图。

在其核心层面，这是在UITableView中显示“工作”的代码

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyBasicCell"]; ScaryBugDoc *bug = [self.bugs objectAtIndex:indexPath.row]; cell.textLabel.text = bug.data.title; cell.imageView.image = bug.thumbImage; return cell; } 

更新

这里是我用代码和照片生成leaderbord数据的代码，希望你可以适当修改它，但不应该太不同

 -(void)getScoresAndAliasForLeaderboard:(GKLeaderboard *)leaderboardRequest{ if (leaderboardRequest == nil) { leaderboardRequest = [[GKLeaderboard alloc] init]; leaderboardRequest.playerScope = GKLeaderboardPlayerScopeFriendsOnly; leaderboardRequest.timeScope = GKLeaderboardTimeScopeAllTime; leaderboardRequest.category = @"HighScore"; leaderboardRequest.range = NSMakeRange(1,100); } [leaderboardRequest loadScoresWithCompletionHandler: ^(NSArray *scores, NSError *error) { if (error != nil) { // Handle the error. } if (scores != nil) { NSMutableArray *retrievePlayerIDs = [[NSMutableArray alloc] init]; for (GKScore *s in scores) { [retrievePlayerIDs addObject:s.playerID]; GCLeaderboardScore *playerScore = [[GCLeaderboardScore alloc] init]; playerScore->playerID = s.playerID; playerScore->score = (int)s.value; playerScore->rank = s.rank; playerScores[s.playerID] = playerScore; //playerScores is a NSMutableDictionary if ([s.playerID isEqualToString: leaderboardRequest.localPlayerScore.playerID]){ me = playerScore; } } if (me == nil){ me = [[GCLeaderboardScore alloc] init]; me->playerID = leaderboardRequest.localPlayerScore.playerID; me->score = leaderboardRequest.localPlayerScore.value; me->alias = @"Me"; playerScores[me->playerID] = me; } [GKPlayer loadPlayersForIdentifiers:retrievePlayerIDs withCompletionHandler:^(NSArray *playerArray, NSError *error) { for (GKPlayer* p in playerArray) { GCLeaderboardScore *playerScore = playerScores[p.playerID]; playerScore->alias = p.alias; [p loadPhotoForSize:GKPhotoSizeSmall withCompletionHandler:^(UIImage *photo, NSError *error) { if (photo != nil) { playerScore->photo = photo; } else{ playerScore->photo = [UIImage imageNamed:@"wordpress_avatar.jpg"]; } if (error != nil) { NSLog(@"%@", error.localizedDescription); } }]; } }]; } }]; }
