Changing items in TTLauncherView according to TabBar

I'm developing an iPhone application using the Three20 library. The main screen is a TTLauncherView (with images inside, like Facebook) and a TabBar at the bottom. Each time a new item is selected in the TabBar, I have to change the images inside my TTLauncherVi开发者_如何学Pythonew.

I thought that I only had to change the "pages" property of my TTLauncherView, but it doesn't work. Nothing is displayed.

What am I doing wrong ? Is there a way to achieve this simple task ?

Thanks in advance

No, this is not simple. You have to create multiple TTLauncherView to populate into your TabBar view controllers, not by changing the pages property.
