UIWebView how to add bookmarks and history features?

UIWebView done with a simple browser, just add the address bar.
Now want to add a bookmark and a history function. I guess they should be able to call an interface UIWebView and read bookmarks and history data, and then displayed on the list control.
Also want to add a function to display the progress of the web page is loaded. Which interfaces should tune?
