Answer 1

If you use a UIWebView then you have html markup available to you. So you could do something like this:

NSString *html = @"This is a very nice <font color=\"green\">#thing</font>";
[myWebView loadHTMLString:html baseURL:[NSURL URLWithString: @"http://localhost"]];

Answer 2

You need to use UIWebView and make the clickable items standard HTML anchors then monitor the link loading in UIWebViewDelegate method shouldStartLoadWithRequest

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    NSURL* u = [request URL];

    if( [[u scheme] isEqualToString:@"showlicenses"] ) {
     NSString *path = [[NSBundle mainBundle] 
      pathForResource:@"credits" ofType:@"html" inDirectory:@"help"];

     LicensesWebviewController *vc = [[LicensesWebviewController alloc] initWithURL:[NSURL fileURLWithPath:path]];
     vc.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
     [self presentModalViewController:vc animated:YES];
     [vc release];

     return NO; // DO NOT attempt to load URL
    }

    return YES; // if you want to allow the URL to load
}

You'll need to set the delegate on your UIWebView.

myWebView.delegate = self;

So anytime a link in my HTML page with the format: "showLicenses://blahblah" is tapped, I push a new view controller.

You can use any type of links you want, you just have to examine and trap the ones you want handled internally. e.g., "myscheme:///do/something/with/this/link"
