Question

我在客观c客户端使用Socket IO swift client，我无法加入特定房间，因为我需要通过房间来加入房间ID：

 /**
 * join room
 *
 * @on   -> 'join'
 *
 * @access  -> user
 *
 * @param   ->
 *          |room      {messagingId}
 *
 * @emit  -> {status:, message}
 */

我找到的只是：

  [socket on:@"join" callback:^(NSArray* data, SocketAckEmitter* ack) {
    NSLog(@"join=>%@", data);
  }];

我的问题是如何将messaginID作为参数传递？

感谢。

Answer 1

首先，为了清楚起见，进行一些描述

/ ** 为事件添加侦听器。返回：处理程序的唯一ID * /

 public func on(event: String, callback: NormalCallback) -> NSUUID

/ ** 向服务器发送消息 * /

public func emit(event: String, _ items: AnyObject...)

回答您的问题

on（event：String，callback：NormalCallback） - ＆gt;您正在使用的NSUUID方法只会从Server获取响应，以便在代码下面发送数据

所以你需要使用emit来加入空间

[socket emit: @"join", messaginID];

[socket on:@"error" callback:^(NSArray * _Nonnull arrayData, SocketAckEmitter * _Nonnull ack) {

[socket setReconnects:YES];
[socket connect];
