Question

我正在使用https://github.com/pkyeck/socket.IO-objc基于iOS7的socket.io-obj库，但我发现当套接字因网络环境不良而断开服务器时，我的应用程序会挂起很长时间。这是我的代码：

#define NOTE_CENTER [NSNotificationCenter defaultCenter]
-(void)connectServer
{
    [socketIO connectToHost:SOCKETADDRESS
                     onPort:SOCKETPORT
                 withParams:nil
     ];
    status = Connecting;
    NSLog(@"%@",socketIO.debugDescription);
    [[] postNotificationName:kConnectingServer object:nil];
}

-(void)disConnectServer
{
    [socketIO disconnect];
}

-(BOOL)hasConnected {
    if (status==Connected) {
        return true;
    }
    return false;
}
-(NetworkStatus)networkStatus
{
    return status;
}

-(void) sendEvent:(OrderEvent)eventIndex withData:(NSDictionary *)data
{
    if (status==Connected) {
        [socketIO sendEvent:@"close" withData:data];
        //[socketIO sendEvent:[NSString stringWithFormat:@"%lu",eventIndex] withData:data];
    }
}

-(void) sendEventWithName:(NSString*)eventName withData:(NSDictionary *)data
{
    if (status==Connected) {
        [socketIO sendEvent:eventName withData:data];
    }
}
#pragma socketIO Delegate methods
- (void) socketIODidConnect:(SocketIO *)socket
{
    status = Connected;
    [NOTE_CENTER postNotificationName:kConnectedServer object:nil];
}

- (void) socketIODidDisconnect:(SocketIO *)socket disconnectedWithError:(NSError *)error
{
    status = OffLine;
    NSLog(@"socket.io disconnected. did error occur? %@", error);
    [NOTE_CENTER postNotificationName:kDisConnectedServer object:nil];
}

- (void) socketIO:(SocketIO *)socket onError:(NSError *)error
{
    [socket  disconnectForced];
    [NOTE_CENTER postNotificationName:kConnecteServerError object:nil];
    if ([error code] == SocketIOUnauthorized) {
        NSLog(@"not authorized");
    } else {
        NSLog(@"onError() %@", error);
    }
}

- (void) socketIO:(SocketIO *)socket didReceiveJSON:(SocketIOPacket *)packet
{
}

- (void) socketIO:(SocketIO *)socket didReceiveEvent:(SocketIOPacket *)packet
{
    NSLog(@"didReceiveEvent()");
    // test acknowledge
    NSString *packName = [packet name];
    //if (packet.name) {
    [NOTE_CENTER postNotificationName:packName object:nil userInfo:[[NSDictionary alloc] initWithObjectsAndKeys:[packet data],@"data", nil]];
    //}
    /*
    SocketIOCallback cb = ^(id argsData) {
        NSDictionary *response = argsData;
        // do something with response
        NSString *packetName = [response  stringValueForKey:@"name"];
        [NOTE_CENTER postNotificationName:packetName object:nil userInfo:response];
    };*/
}

我发生的另一个问题是当我调用“[socketIO disconnect]”时，服务器不会立即断开我的应用程序。请帮我找到这些问题的答案。

非常感谢。

对于迟到的回复我很抱歉。我发现如果你的socket.io服务器在尝试 disconnectForced 时关闭，那么UI将会阻塞，因为如果你看一下这个方法，请求是使用 sendSynchronousRequest

您可以尝试修改方法以使用 sendAsynchronousRequest ，但我建议您进一步检查该类。您还可以在使用 disconnectForced 之前检查连接状态。
