EXE_BAD_BADACCESS 正在尝试访问 GKMatch?

EXE_BAD_BADACCESS trying to access GKMatch?

问题简述

尝试使用 gamecenter 与朋友实时玩游戏导致游戏崩溃

项目详情

我的调查

-(void)matchmakerViewController: (GKMatchmakerViewController *) viewController didFindMatch:(GKMatch *)match

我处理邀请的流程

  1. 来自设备 A 的媒人向设备 B 发送有关邀请的通知
  2. 设备 B 打开并重定向到匹配房间
  3. 设备 B 调用以下函数:

{

-(void)player:(GKPlayer *)player didAcceptInvite:(GKInvite *)invite {

 self->inviteStarted((int)invite.playerGroup);

 NSLog(@"didAcceptInvite");

 //Called when another player accepts a match invite from the local player.
 NSLog(@"didAcceptInvite was called: Player: %@  accepted our invitation", player);

 GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:invite] autorelease];

 mmvc.matchmakerDelegate = self;

 [[AppController getViewController] presentViewController:mmvc animated:YES completion:nil];

  }

}

  1. 两个设备调用以下函数:

{

-(void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)match
{

if (match != nil)
{

    [[AppController getViewController] dismissViewControllerAnimated:YES completion:nil];

    NSLog(@"%@", match);

    self->myMatch = match;

    //NSLog(@"Match found count!! %lu", (unsigned long)[self->myMatch retainCount]);

    match.delegate = self;

    if (!self->matchStarted && myMatch.expectedPlayerCount == 0)
    {
        self->matchStarted = YES;

        opponent=[[myMatch players] objectAtIndex:0];

        self->matchBegan();

        [self loadOppPhoto];
    }
}
}

}

  1. 设备 A 向设备 B 发送数据 (此处发生崩溃)

{ -(无效)sendDataToOppUnreliable:(NSString*)str

{


NSError *error=nil;

NSData *packet = [str dataUsingEncoding:NSUTF8StringEncoding];
//NSLog(@"this: %@", self);

//NSLog(@"Match found count!! %lu", (unsigned long)[self->myMatch retainCount]);

//NSLog(@"match: %@", self->myMatch);//EXC_BAD_ACCESS 

[myMatch sendDataToAllPlayers: packet withDataMode: 

GKMatchSendDataUnreliable error:&error];//EXC_BAD_ACCESS

if (error!=nil)
{
    NSLog(@"Error in sending data: %li", (long)[error code]);
}
}

}

感谢您的帮助:)

  • GKMatch 属性 已设置为(分配)并且需要更改为 (保留)
  • GKMatch 对象需要在开始时初始化为 nil 所以 可以用
