Question

我正在为我当前的项目使用robbiehanson / XMPPFramework。如何使用XMPPFramework获取消息输入状态？有XEP-184协议，但现在已弃用。需要帮助来获取iOS中的撰写状态。问候，铢

首先导入：

#import "XMPPMessage+XEP_0085.h"

然后根据您的目的添加以下方法。

.....构成

- (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];
}

有效.....

- (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];
}

无效...

- (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];
}

...飘

- (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];
}

...暂停

- (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];
}

然后您应该在appdelgate中编写以下代码。（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"] ) {


        }
}

＆＃34;联系人最常用的协议是输入＆＃34;通知是XEP-0085: Chat State Notifications。如那里更详细地描述的那样，给联系人的第一条消息应该包含一个＆＃34; active＆＃34; state元素（<body/>元素旁边）：

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

如果联系人以聊天状态响应，则客户端可以继续使用其他状态，例如＆＃34;撰写＆＃34;：

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

或＆＃34;暂停＆＃34; （用户输入了文字，但没有主动输入）：

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

或＆＃34;不活跃＆＃34;，最后＆＃34;去了＆＃34;当用户通过关闭聊天窗口或类似内容结束对话时。

XMPPFramework＆＃34;输入...＆＃34;消息的状态
