NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:] , @"actcode",nil];

    //首先设置需要通知的方法。加入通知中心。比如当程序跑到这时就通知游戏

    [[NSNotificationCenter defaultCenter] postNotificationName:gameStartNotification object:nil userInfo:dic];

//调用时--------------------------------------------

//注册消息通知  捕获游戏start时的方法

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(testNotify:) name:gameStartNotification object:nil];

//实现方法

-(void)testNotify:(NSNotification*)notify
