Question

我有一个typedef结构

typedef struct {
    Message message;
    uint32_t randomNumber;
} MessageRandomNumber;

我有这个代码将随机数发送给GKMatch中的所有其他玩家：

-(void)sendRandomNumber {

MessageRandomNumber message;
message.message.messageType = kMessageTypeRandomNumber;
message.randomNumber = _ourRandomNumber;
NSLog(@"My random number is %d", _ourRandomNumber);
NSData * data = [NSData dataWithBytes:&message length:sizeof(MessageRandomNumber)];
NSLog(@"Sent my random number to the other players");
[MultiplayerNetworking sendData:data];
}

+(void)sendData:(NSData *)data {

NSError * error;

GCTurnBasedMatchHelper * gamekitHelper = [GCTurnBasedMatchHelper sharedGameKitHelper];

BOOL success = [gamekitHelper.match sendDataToAllPlayers:data withDataMode:GKMatchSendDataReliable error:&error];
NSLog(@"Sent data to all players %s ", success ? "Successfully" : "has failed");

gamekitHelper = nil;

if (!success) {

    NSLog(@"Error sending data:%@", error.localizedDescription);

    [[GCTurnBasedMatchHelper sharedGameKitHelper] appAlert:@"Error Sending Data" alertMessage:[NSString stringWithFormat:@"%@", error.localizedDescription] viewController:[DominoTableViewController dominotableViewController] gkMatchDisconnect:true];
}
}

我有以下代码来接收GKMatch中所有其他玩家的随机数：

-(void)match:(GKMatch *)match didReceiveData:(NSData *)data fromPlayer:(NSString *)playerID {
Message * message = (Message *)[data bytes];

    if (message->messageType == kMessageTypeRandomNumber) {

        MessageRandomNumber * messageRandomNumber = (MessageRandomNumber *) [data bytes];
        NSLog(@"Received random number: %d", messageRandomNumber- >randomNumber);

我的问题是，在我的iPhone 5（无SIM卡，iOS 9.3.1）和iPod Touch（第5代）上，messageRandomNumber-＆gt; randomNumber在收到其他3名玩家的随机数时总是等于0在比赛中连接。这个完全相同的代码在iphone 5s上运行得很好（没有SIM卡，iOS 9.3.1）。这种行为有解释吗？
