You need to use the methods in the delegate to handle authentication. First you need to connect to the server if it's not already connected:
[_xmppStream connectWithTimeout:10 error:&error];
Once the stream is connected to the server the delegate method will be invoked:
- (void)xmppStreamDidConnect:(XMPPStream *)sender;
Inside that method, you can call authenticateWithPassword
. If the stream was previously connected (would be the else part of the if you posted) you can just call authenticateWithPassword
.
If authentication fails, the following delegate method is called:
- (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(NSXMLElement *)error;
There you can decide to show a message to the user and start over. If authentication succeeds, the following method is called:
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender;
