XMPPFramework“键入.”消息状态

Question

我在当前的项目中使用robbiehanson/XMPPFramework。如何使用XMPPFramework获取消息输入状态？这里有XEP- 184协议，但现在已经不推荐了。在iOS中获取合成状态需要帮助。你好，Bhat

Answer 1

“联系人是输入”通知最常用的协议是XEP-0085:聊天状态通知。如前所述，给联系人的第一条消息应该包含一个“活动”状态元素(在<body/>元素旁边)：

<active xmlns='http://jabber.org/protocol/chatstates'/>

如果联系人以聊天状态进行响应，则客户端可以继续使用其他状态，如“合成”：

<composing xmlns='http://jabber.org/protocol/chatstates'/>

或“暂停”(用户已输入文本，但未主动键入)：

<paused xmlns='http://jabber.org/protocol/chatstates'/>

或“非活动”，并最终“消失”时，用户结束对话关闭聊天窗口或类似的。

首先您需要导入：

#import "XMPPMessage+XEP_0085.h"

然后根据你的目的添加以下方法。

作曲……

- (void)sendComposingChatToUser:(XMPPJID*)jid {
    NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
    [message addAttributeWithName:@"type" stringValue:@"chat"];
    [message addAttributeWithName:@"to" stringValue:[jid full]];
    XMPPMessage *xmppMessage = [XMPPMessage messageFromElement:message];
    [xmppMessage addComposingChatState];
    [xmppStream sendElement:message];
}

活跃.

- (void)sendActiveChatToUser:(XMPPJID*)jid {
    NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
    [message addAttributeWithName:@"type" stringValue:@"chat"];
    [message addAttributeWithName:@"to" stringValue:[jid full]];
    XMPPMessage *xmppMessage = [XMPPMessage messageFromElement:message];
    [xmppMessage addActiveChatState];
    [xmppStream sendElement:message];
}

不活跃..。

- (void)sendInactiveChatToUser:(XMPPJID*)jid {
    NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
    [message addAttributeWithName:@"type" stringValue:@"chat"];
    [message addAttributeWithName:@"to" stringValue:[jid full]];
    XMPPMessage *xmppMessage = [XMPPMessage messageFromElement:message];
     [xmppMessage addInactiveChatState];
    [xmppStream sendElement:message];
}

走了..。

- (void)sendExitChatToUser:(XMPPJID*)jid {
    NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
    [message addAttributeWithName:@"type" stringValue:@"chat"];
    [message addAttributeWithName:@"to" stringValue:[jid full]];
    XMPPMessage *xmppMessage = [XMPPMessage messageFromElement:message];
    [xmppMessage addGoneChatState];
   [xmppStream sendElement:xmppMessage];
}

停下来..。

- (void)sendPausedChatToUser:(XMPPJID*)jid {
    NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
    [message addAttributeWithName:@"type" stringValue:@"chat"];
    [message addAttributeWithName:@"to" stringValue:[jid full]];
    XMPPMessage *xmppMessage = [XMPPMessage messageFromElement:message];
    [xmppMessage addPausedChatState];
    [xmppStream sendElement:message];
}

然后，您应该用appdelgate编写以下代码。(didReceiveMessage)方法。

例如：

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message{
    if ([message isChatMessageWithBody]){
}
else{
if([message elementForName:@"composing"] != nil){



        } else if ([message elementForName:@"paused"] != nil) {



        } else if ([message elementForName:@"gone"] || [message elementForName:@"inactive"] ) {


        }
}
