Question

我正在尝试使用媒人制作自定义配对视图。以下代码用于查找匹配项。

当我在具有不同Game Center帐户的两个不同设备上运行此操作时，两者都将获得匹配但没有一个将连接到匹配。他们只会陷入无限的while循环中，永远不会离开。我错过了什么，你需要打电话来实际连接到比赛吗？

- (void) findMatch{
GKMatchRequest *request = [[GKMatchRequest alloc] init];
request.minPlayers = 2;
request.maxPlayers = 2;
request.playersToInvite = nil;
NSLog(@"Start searching!");

[matchmaker findMatchForRequest:request
               withCompletionHandler:^(GKMatch *match, NSError *error)
 {
     if (error) {
         // Print the error
         NSLog(@"%@", error.localizedDescription);
     }
     else if (match != nil)
     {
         curMatch = match;
         curMatch.delegate = self;


         NSLog(@"Expected: %i", match.expectedPlayerCount);

         while (match.expectedPlayerCount != 0){
             NSLog(@"PLayers: %i", curMatch.playerIDs.count);
         }
         NSLog(@"Start match!");
     }
 }];

你不应该使用while循环来等待expectedPlayerCount达到0，而是实现GKMatchDelegate方法：

- (void)match:(GKMatch *)match player:(NSString *)playerID didChangeState:(GKPlayerConnectionState)state {
    if (!self.matchStarted && match.expectedPlayerCount == 0) {
        self.matchStarted = YES;
        //Now you should start your match.
    }
}
