XMPP 基於XML的點對點通訊協議

XMPP 基於XML的點對點通訊協議

 

IM: 即時通訊

XMPP: 基於XML的點對點通訊協議

1. ejabber: 這個軟件是用來開啓本地服務器使用, 本地服務器地址爲: 127.0.0.1, 全部的電腦都同樣, 開啓服務器的軟件有不少

2. Audium: 就是一個聊天工具

用局域網聊天

1.在同一個WIFI下

2.在同一個本地服務器建立帳號

3.登錄的時候, 設置好服務器地址, 爲電腦的IP地址

XAMPP: 集成了阿帕奇 FTP和My SQL的一個軟件

類的擴展有三種方式

1.協議: 須要本身制定協議, 設置代理, 遵照協議, 通常用來傳值(回調)

2.延展: 爲類添加私有方法和私有變量, 通常用於已知類(.h和.m都存在的類)

3.類目: 爲類添加方法和屬性(只有setter和getter, 沒有實例變量), 必須實現內部聲明的方法, 通常用於系統類的擴展

XMPP的安裝

XMPP安裝須要的軟件

    

安裝ejabberd

選擇ejabberd.app進行安裝

 

 

 

用戶名和密碼填寫完要記住，以後會用到

安裝成功後，在Finder->應用程序->ejabberd-14.07->bin->start點擊start.exec運行，會跳出一個網頁

在網頁上能夠添加帳號和密碼

 

將 軟件添加到Finder->應用程序中，點擊打開app，能夠用ejabberd中註冊的帳號和密碼登錄

詳細代碼：

在工程中添加框架和MI類
