[iPhone] Launch Safari from a link in a UIWebView?

Question

I have a UIWebView with my app's built-in help documentation. I have a few links in these bundled pages that I would like to open in mobile Safari. Obviously, these links just load in my app's UIWebView. If you add target="_blank" to the link, the UIWebView does nothing when the link is clicked. I can't find any url schemes that will launch Safari that wouldn't also be handled by the web view.
So if this is even possible, how can it be done?

You'll have to forgive me, but I am a complete newbie to XCode - and I have been playing with the myGoogle example as a starting point to fumbling around the application; but I'm really not sure where your code needs to be added.
I also found another example on dougdiego.com, which extends your concept to keep relative links within WebView, but send anything beginning http/https (and therefore likely to be external) to Safari;
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
   navigationType:(UIWebViewNavigationType)navigationType; {
   NSURL *requestURL =\[ \[ request URL ] retain ];
   // Check to see what protocol/scheme the requested URL is.
   if ( ( \[ \[ requestURL scheme ] isEqualToString: @"http" ]
      || \[ \[ requestURL scheme ] isEqualToString: @"https" ] )
      && ( navigationType == UIWebViewNavigationTypeLinkClicked ) ) {
      return !\[ \[ UIApplication sharedApplication ] openURL: \[ requestURL autorelease ] ];
   // Auto release
   \[ requestURL release ];
   // If request url is something other than http or https it will open
   // in UIWebView. You could also check for the other following
   // protocols: tel, mailto and sms
   return YES;
The narrative alongside the above code said "The method shouldStartLoadWithRequest is a delegate method that is called when a link is clicked on. You can override the method and tell it to open in Safari.", which is all very well - but I suspect I need to understand what a delegate method is, and how I override it
Any help would be much appreciated.
