一点一滴慢慢的揭开XMPP的神秘面纱

xmpp.jpg

XMPP是干嘛的在此就不多探讨了，我也是刚开始尝试着学习。首先我们把XMPP拉进工程，然后必须导入的几个框架： CFNetwork.framework Security.framework libxml2.dylib libresolv.dylib SystemConfiguration.framework CoreLocation.framework AudioToolbox.framework AVFoundation.framework 运行下不报错就对了。。。。。在我们开发中做聊天的话，我们首先是需要登陆，登陆之后获取用户的信息，获取到信息之后我们判断下该用户是否已经在Openfire存在，不存在就直接给用户注册，存在就自动赋值登陆Openfire [self XmppLogin:dic];

更多经验请点击

代码语言：javascript复制

#pragma mark 登陆xmpp
-(void)XmppLogin:(NSDictionary*)userdic{
    App.IM_Account =  [NSString stringWithFormat:@"Bison%@",App.UserId];//拼上前缀
    App.IM_Password =  @"**************";
    [[JEXMPP Shared] XmppLogin];
}

代码语言：javascript复制

#pragma mark -  登录 退出
-(BOOL)XmppLogin{
    if (![XMPP_Stream isDisconnected]) {
        return YES;
    }
    [XMPP_Stream setHostName:kIM_Host];//设置服务器
    [XMPP_Stream setHostPort:[kIM_Port intValue]];//设置端口

    NSLog(@"jid:%@ ps:%@",App.IM_Account,App.IM_Password);
    if (App.IM_Account == nil || App.IM_Password == nil) {
        return NO;
    }

 XMPPJID *myjid = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@%@",App.IM_Account,kIM_Domain] resource:@"jp"];//设置了 jid 的 resource 即限制了多点登陆
    
    NSError *error ;
    [XMPP_Stream setMyJID:myjid];
    if (![XMPP_Stream connectWithTimeout:XMPPStreamTimeoutNone error:&error]) {
        NSLog(@"my connected error : %@",error.description);
        return NO;
    }
    return YES;
}

接下来就是验证是否登陆了Openfire

代码语言：javascript复制

//将要连上
- (void)xmppStreamWillConnect:(XMPPStream *)sender{
    NSLog(@"==xmppStreamWillConnect");
}
//连上了 还要验证密码
- (void)xmppStreamDidConnect:(XMPPStream *)sender{
    NSLog(@"xmppStreamDidConnect");
    if (App.IM_Password) {
        NSError *error ;
        if (![XMPP_Stream authenticateWithPassword:App.IM_Password error:&error]) {
            NSLog(@"error authenticate : %@",error.description);
        }
    }
}

//突然掉线了
- (void)xmppReconnect:(XMPPReconnect *)sender didDetectAccidentalDisconnect:(SCNetworkReachabilityFlags)reachabilityFlags {
    NSLog(@"didDetectAccidentalDisconnect : n %u ", reachabilityFlags);
}
//YES 重连 
- (BOOL)xmppReconnect:(XMPPReconnect *)sender shouldAttemptAutoReconnect:(SCNetworkReachabilityFlags)reachabilityFlags{
    NSLog(@"shouldAttemptAutoReconnect : n %u ", reachabilityFlags);
    return YES;
}

#pragma mark 发送 成功  失败
- (void)xmppStream:(XMPPStream *)sender didSendMessage:(XMPPMessage *)message{

}
//发送失败
- (void)xmppStream:(XMPPStream *)sender didFailToSendMessage:(XMPPMessage *)message error:(NSError *)error{

}
//发送 成功或失败的 反馈给聊天页面
-(void)XmppSend_Status:(NSInteger)status Msg:(JEChatMessage *)msg{
    NSLog(@"XmppSend_Status 消息发送:%@ n内容:%@", status == 1 ? @"成功" : @"失败",msg.TextContent);
   
   
}

#pragma mark 接收消息
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message{
    NSLog(@"%@n 来新消息了n from:%@n to:%@n type:%@n message:%@n body:%@",message,[[message attributeForName:@"from"] stringValue],[[message attributeForName:@"to"] stringValue],[[message attributeForName:@"type"] stringValue],[[message attributeForName:@"message"] stringValue],[[message elementForName:@"body"] stringValue]);
}

推荐一款学习iOS开发的app_____|______| | 传送门今天暂时讲到这。。。。。有不足之处希望大家指点出来哦，因为我也对xmpp刚接触不久技术交流群：534926022（免费） 511040024(0.8/人付费) 原文在：http://www.allluckly.cn/ 版权归©Bison所有如需转载请保留原文超链接地址！否则后果自负！
