一点一滴慢慢的揭开XMPP的神秘面纱

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

#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];
}

#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

//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]);
}

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
