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。

1.app演示

才知道简书不支持video

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 = @"";
}

}];

不管大佬们关不关注公众号，我都会放上本章的Demo
