There is an example app which you can find in Apple's XCode documentation, it's the KMLViewer.

The App shows how to open KML files. The parsing of the XML is done by hand, there is no library which handles this for you! But the example is very good.

To list your files you'll probably want to use a UITableView. You should read into the documentation first before using it.

Check out this thread. It worked for me.
