Easy implementation of XMPP Instant Messaging for iOS development

Server and database are installed first

With the server, I'm using OpenFire, the database is MySQL.

Two links recommended here

Configuring the server OpenFire

Http://www.cnblogs.com/xiaodao/archive/2013/04/05/3000554.html

First configure the database and then configure the server.

All two open.

The next XMPP client, which is used to test the

I'm under the Adium.

Down here.

http://xmpp.org/xmpp-software/clients/

Then add the account in Adium, the server will be set up with OpenFire 127.0.0.1, Port 5222

Here OpenFire the server port inside, 5222 is the client connection server

After successful login, you can see that the user is online in OpenFire.

Then another client, I directly with the code, feel trouble did not do interface

Set Xmppstream

Then set the account, at least test, so directly in the Viewdidload wrote

Then is to verify the password, the following method is on-line, these are proxy methods, Remember to set Xmppstream agent

This is the way to receive information, I do not interface, directly print out the accepted information

This method is called if the validation fails.

At first I run the error that always returns XMPP validation failed

Later in OpenFire view username must be with server name

For example, my account is test123, set Jid username is [email protected]

Then run, no error, in OpenFire display already online

Then you can start chatting, the following is the first hair, the above is the previous chat record

Sent a text and a link

Then Xcode outputs

Instant Messaging is the simplest way to get out of the app and the OpenFire backstage will show the offline
