XMPPFramework - 如何创建MUC会议室并邀请用户？ [英] XMPPFramework - How to create a MUC room and invite users?

问题描述

我正在使用Robbiehanson的iOS XMPPFramework。我正在尝试创建一个MUC会议室并邀请用户加入群聊室，但它无法正常工作。

I am using Robbiehanson's iOS XMPPFramework. I am trying to create a MUC room and invite a user to the group chat room but it is not working.

我使用以下代码：

XMPPRoom *room = [[XMPPRoom alloc] initWithRoomName:@"[e-mail]/room" nickName:@"room"];
[room createOrJoinRoom];
[room sendInstantRoomConfig];
[room setInvitedUser:@"[e-mail]"];
[room activate:[self xmppStream]];    
[room inviteUser:jid1 withMessage:@"hello please join."];
[room sendMessage:@"HELLO"];

用户[e-mail]应该收到邀请信息但没有任何事情发生。

The user [e-mail] should receive the invite message but nothing is happening.

任何帮助将不胜感激。 ：）

Any help will be appreciated. :)

推荐答案

在探索各种解决方案之后，我决定在这里编译和分享我的实现：

After exploring various solutions, I've decided to compile and share my implementation here:

1. 创建XMPP会议室：

XMPPRoomMemoryStorage *roomStorage = [[XMPPRoomMemoryStorage alloc] init];

/** 
 * Remember to add 'conference' in your JID like this:
 * e.g. [e-mail]
 */

XMPPJID *roomJID = [XMPPJID jidWithString:@"[e-mail]"];
XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomStorage
                                                       jid:roomJID
                                             dispatchQueue:dispatch_get_main_queue()];

[xmppRoom activate:[self appDelegate].xmppStream];
[xmppRoom addDelegate:self 
        delegateQueue:dispatch_get_main_queue()];

[xmppRoom joinRoomUsingNickname:[self appDelegate].xmppStream.myJID.user 
                        history:nil 
                       password:nil];

检查此代表是否成功创建了房间：

Check if room is successfully created in this delegate:

- (void)xmppRoomDidCreate:(XMPPRoom *)sender

检查您是否已加入此代表中的房间：

Check if you've joined the room in this delegate:

- (void)xmppRoomDidJoin:(XMPPRoom *)sender

创建房间后，获取房间配置表格：

After room is created, fetch room configuration form:

- (void)xmppRoomDidJoin:(XMPPRoom *)sender {
    [sender fetchConfigurationForm];
}

配置房间

Configure your room

/**
 * Necessary to prevent this message: 
 * "This room is locked from entry until configuration is confirmed."
 */

- (void)xmppRoom:(XMPPRoom *)sender didFetchConfigurationForm:(NSXMLElement *)configForm 
{
    NSXMLElement *newConfig = [configForm copy];
    NSArray *fields = [newConfig elementsForName:@"field"];

    for (NSXMLElement *field in fields) 
    {
        NSString *var = [field attributeStringValueForName:@"var"];
        // Make Room Persistent
        if ([var isEqualToString:@"muc#roomconfig_persistentroom"]) {
            [field removeChildAtIndex:0];
            [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
        }
    }

    [sender configureRoomUsingOptions:newConfig];
}

邀请用户

- (void)xmppRoomDidJoin:(XMPPRoom *)sender 
{
    /** 
     * You can read from an array containing participants in a for-loop 
     * and send multiple invites in the same way here
     */

    [sender inviteUser:[XMPPJID jidWithString:@"keithoys"] withMessage:@"Greetings!"];
}

在那里，你' ve创建了一个XMPP多用户/组聊天室，并邀请了一位用户。 ：）

There, you've created a XMPP multi-user/group chat room, and invited a user. :)
