前沿

本章主要介绍如何在iOS端实现单聊和群聊，服务端是本地搭建，数据库使用mysql。

第一篇：即时通信解决方案
第二篇：推送解决方案
第三篇：Web端匿名聊天
第四篇：iOS集成单聊&群聊

2.单聊实现工程

2.1.登录

   [[SocketIOManager sharedInstance] emitOrder:@"login" with:@{@"userID":self.userField.text,@"type":@"chat"}];

2.2.选择好友

    [[SocketIOManager sharedInstance] emitOrder:@"userList" with:@{}];

2.3.聊天

    NSMutableDictionary *dic = [NSMutableDictionary dictionary];
    
    [dic setValue:self.toUser forKey:@"toUser"];
    [dic setValue:self.currentUser forKey:@"fromUser"];
    [dic setValue:self.msgField.text forKey:@"msg"];
    [dic setValue:@"chat" forKey:@"type"];
    [dic setValue:@"" forKey:@"ext"];
    
    //发送order
    [[SocketIOManager sharedInstance] emitOrder:@"sendMsg" with:dic];

3.群聊实现过程

3.1.登录

  [[SocketIOManager sharedInstance] emitOrder:@"login" with:@{@"userID":self.userField.text,@"type":@"roomChat"}];

3.2.获取房间列表

    [[SocketIOManager sharedInstance] emitOrder:@"roomList" with:@{}];

    [[SocketIOManager sharedInstance] onOrder:@"roomList" completion:^(id  _Nonnull response) {

        NSArray *roomList = response[0][@"roomList"];
        
        if (roomList.count) {
            [roomList enumerateObjectsUsingBlock:^(NSMutableDictionary *obj, NSUInteger idx, BOOL * _Nonnull stop) {
                NSLog(@"=====%@",obj);
                if ([obj[@"roomid"] intValue] != 0) {
                    NSInteger index = [obj[@"roomid"] intValue]-1;
                    NSMutableDictionary *dd = self.roomListArray[index];
                    [dd setValue:obj[@"number"] forKey:@"number"];
                }
            }];
            [self.roomListTableView reloadData];
            [self.roomListTableView.mj_header endRefreshing];
            
        }else {
            NSLog(@"没有用户");
        }
    }];

3.3.选择房间

[[SocketIOManager sharedInstance] emitOrder:@"join" with:@{@"userID":self.uid,@"roomid":info[@"roomId"]}];

[[SocketIOManager sharedInstance] onOrder:@"join" completion:^(id  _Nonnull response) {
        
        NSString *msg = response[0][@"msg"];
        
        if ([msg isEqualToString:@"1"]) {

            RoomChatViewController *roomChatVC = [RoomChatViewController new];
            roomChatVC.roomid = response[0][@"roomid"];
            roomChatVC.uid = self.uid;
            [self.navigationController pushViewController:roomChatVC animated:YES];

        }else {
            NSLog(@"用户进入房间失败");
        }
    }];

3.4.开始聊天

 NSMutableDictionary *dic = [NSMutableDictionary dictionary];
    
    [dic setValue:@"" forKey:@"toUser"];
    [dic setValue:self.uid forKey:@"fromUser"];
    [dic setValue:self.msgField.text forKey:@"msg"];
    [dic setValue:@"roomChat" forKey:@"type"];
    [dic setValue:@"" forKey:@"ext"];
    
    if (self.msgField.text.length) {
        //发送order
        [[SocketIOManager sharedInstance] emitOrder:@"sendMsg" with:dic];
    }else {
        NSLog(@"不能发送空消息");
    }

[[SocketIOManager sharedInstance] onOrder:@"sendMsg" completion:^(id  _Nonnull response) {
        
        if (response) {
            MessageModel *model = [[MessageModel alloc] init];
            model.toUser = response[0][@"toUser"];
            model.fromUser = response[0][@"fromUser"];
            model.msg = response[0][@"msg"];
            model.type = response[0][@"type"];
            model.ext = response[0][@"ext"];
            
            [self.dataArray addObject:model];

            [self.chatTableView reloadData];
            [self scrollTableViewToBottom];
            
            self.msgField.text = @"";
        }
        
    }];
