use tab buttons to control UIWebView - navigate to URL

[newbiedewbie]

I created a very basic app that contains a single UIWebView and a tab bar. I am attempting the following behavior:

simple UIWebView and a tab navigation bar at the bottom. I am wondering how to connect the tab buttons to load different webpages in the webview like this:

User clicks
BUTTON1-> webview navigates to URL1
BUTTON2-> webview navigates to Url2.com - url codes Resources and Information.
BUTTON3-> webview navigates to Url2.com - url codes Resources and Information.

I searched the forums and found a similar question... but NO RESPONSE

Thanks in advance.

Use UIWebView's loadRequest.
