iOS Development--xmppframewok framework based on XMPP Protocol (ii): Server connection

Things to prepare before connecting to the server:

1. Build the XMPP server

2. Set the server address and port

[_xmppstream sethostname:@ "127.0.0.1"];

[_xmppstream sethostport:5222];

3. Call Connect

Key items:

jid-format must be "username" + "@" + "server Address" example: [email protected]

The connection server must be Jid set, if no account can set any value

　　

The specific code is as follows:

-(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:Tenerror:&ERROR]; if(Error) {NSLog (@"Connection Failed%@", error); }        returnYES;}

Callback results returned by the connection

///Connection Successful- (void) Xmppstreamdidconnect: (Xmppstream *) sender{NSLog (@"Connection Successful"); Isxmppconnected=YES; if(_islogined) {Nserror*error =Nil; if(! [Self Xmppstream] Authenticatewithpassword:password error:&ERROR]) {NSLog (@"Error authenticating:%@", error); }    }}///Connection Failed- (void) Xmppstreamdiddisconnect: (Xmppstream *) sender Witherror: (Nserror *) error{NSLog (@"Connection Disconnect"); if(!isxmppconnected) {        //Ddlogerror (@ "Unable to connect to server. Check xmppstream.hostname ");    }}

Disconnect Connection

[_xmppstream disconnect];
