xmppframework - iOS XMPP Framework, how to handle wrong credential? -


all codes use https://github.com/robbiehanson/xmppframework. inside sample code.

in ios7 messaging app, invoke "connect" function inside xmpp framework after user has entered login credential , clicked "login" button. connect function works fine if entered correct credentials first time, not work if user entered wrong credential. because first line inside connect return true:

 if (![_xmppstream isdisconnected]) {         return yes;     }

which means further presses on login button nothing.

should manually invoke authenticatewithpassword? right practice assuming connection between client , server has been setup?

thank you.

you need use methods in delegate handle authentication. first need connect server if it's not connected:

[_xmppstream connectwithtimeout:10 error:&error];

once stream connected server delegate method invoked:

- (void)xmppstreamdidconnect:(xmppstream *)sender;

inside method, can call authenticatewithpassword. if stream connected (would else part of if posted) can call authenticatewithpassword.

if authentication fails, following delegate method called:

- (void)xmppstream:(xmppstream *)sender didnotauthenticate:(nsxmlelement *)error;

there can decide show message user , start over. if authentication succeeds, following method called:

- (void)xmppstreamdidauthenticate:(xmppstream *)sender;
