Излязох от себе си със зомбито. findMatchForRequest: е неадекватен за последователно намиране на съответствие, следователно използването на [addPlayersToMatch:matchRequest:completionHandler:] където вероятно се срива:
-[__NSMallocBlock__ intValue]: unrecognized selector sent to instance
-[CFString retain]: message sent to deallocated instance // NSZombieEnabled
По-долу е целият проект за „минимален работен пример“ (на Dropbox), който рано или късно се срива.
@implementation GameCenterHelper { GKMatch* _currentMatch; }
+ (GameCenterHelper *)sharedInstance {
static GameCenterHelper* sharedHelper;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^ {
sharedHelper = [GameCenterHelper new];
});
return sharedHelper;
}
- (void)authenticateLocalPlayer {
[GKLocalPlayer localPlayer].authenticateHandler = ^(UIViewController *loginViewController, NSError *error) {
[self findMatch];
};
}
- (void)findMatch {
GKMatchRequest *request = [GKMatchRequest new];
request.minPlayers = 2;
request.maxPlayers = 4;
[[GKMatchmaker sharedMatchmaker] findMatchForRequest:request withCompletionHandler:^(GKMatch *match, NSError *error) {
_currentMatch = match;
_currentMatch.delegate = self;
}];
}
- (void)addPlayersToMatch {
GKMatchRequest *request = [GKMatchRequest new];
request.minPlayers = 2;
request.maxPlayers = 4;
[[GKMatchmaker sharedMatchmaker] addPlayersToMatch:_currentMatch matchRequest:request completionHandler:nil];
}
- (void)match:(GKMatch *)match player:(NSString *)playerID didChangeState:(GKPlayerConnectionState)state {
[self addPlayersToMatch];
}
@end
Пропускам ли нещо основно в управлението на паметта на блоковете? Горното се извиква:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[GameCenterHelper sharedInstance] authenticateLocalPlayer];
return YES;
}
Тук няма обработка на грешки и човек трябва да създаде макетно приложение на iTunesConnect, за да изпита срива, в противен случай няма GKMatch се връща. Също така се уверих, че пакетните версии между Xcode и iTunesConnect са съгласни, т.е. 1.0 срещу 1.0.0.
