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);
}
}returnYES;
}
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:10error:&error];if(error)
{
NSLog(@"连接失败%@",error);
}returnYES;
}
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");}
}
断开连接
[_xmppStream disconnect];
