Programming an app similar in appearance to the Facebook app

I'm programming an iPhone application. This application contains a home page, which I would like to be almost the same as the one in facebook for iPhone : rows of icons, each icon corresponding to a category of my application.

I'm a newbie in iPhone development, and I can't find which control is used to show this view. Could someone he开发者_JAVA技巧lp me ?

Thanks in advance

The best bet is to use Three20 library - it is opensource and it is the framework that was used to create an original facebook app. There is a bunch of controls in the framework, TTLauncherView is your friend to create a homescreen.
