连接服务器前需准备事项：

1.搭建好XMPP服务器

2.设置服务器地址和端口

[_xmppStream setHostName:@"127.0.0.1"];

[_xmppStream setHostPort:5222];

3.调用connect

关键项：

JID－格式必须为 "用户名"+"@"+"服务器地址",示例 :user@127.0.0.1

连接服务器必须进行JID设置，如果还没有账号可以设置任意值

具体代码如下：

- (BOOL)connect:(NSString*)user withpassword:(NSString*)pwd
{ if (user != nil) {
user = [NSString stringWithFormat:@"%@@%@",user,_xmppStream.hostName];
}
if (![_xmppStream isDisconnected]) {
if(_isLogined){
NSError *error = nil;
password=pwd;
[[self xmppStream] setMyJID:[XMPPJID jidWithString:user resource:@"ios"]];
if (![[self xmppStream] authenticateWithPassword:password error:&error])
{
NSLog(@"Error authenticating: %@", error);
}
}
return YES;
}
NSString *myJID = user;
NSString *myPassword = pwd;
if ( myPassword != nil) {
password = myPassword;
}
if (myJID != nil) { [_xmppStream setMyJID:[XMPPJID jidWithString:myJID resource:@"ios"]];
}else{
[_xmppStream setMyJID:[XMPPJID jidWithString:_xmppStream.hostName resource:@"ios"]];
}
NSError *error = nil;
[_xmppStream connectWithTimeout: error:&error];
if(error)
{
NSLog(@"连接失败%@",error);
} return YES;
}

连接返回的回调结果

///连接成功
- (void)xmppStreamDidConnect:(XMPPStream *)sender
{
NSLog(@"连接成功");
isXmppConnected = YES;
if(_isLogined){
NSError *error = nil;
if (![[self xmppStream] authenticateWithPassword:password error:&error])
{
NSLog(@"Error authenticating: %@", error);
}
}
}
///连接失败
- (void)xmppStreamDidDisconnect:(XMPPStream *)sender withError:(NSError *)error
{
NSLog(@"连接断开"); if (!isXmppConnected)
{
//DDLogError(@"Unable to connect to server. Check xmppStream.hostName");
}
}
