It depends on where you want to put this link. If it is in a UITextView, you just have to enable it.

textView.text = @"Some text with link in it : http://http://stackoverflow.com";
textView.dataDetectorTypes = UIDataDetectorTypeLink;

More info on iOS reference library.

Or, if you want to open Safari programmatically:

NSURL *url = [ [ NSURL alloc ] initWithString: @"http://stackoverflow.com" ];
[[UIApplication sharedApplication] openURL:url];
[url release];

If you want to share on Facebook, you need to tell Safari to open a URL which will display a Facebook page that allows the user to share. Here is an example:

NSString *urlString = @"http://stackoverflow.com";
//The url you want to share

NSString *title = "The Title of the Page";
//The title you want to be displayed on Facebook

NSString *shareUrlString = [NSString stringWithFormat:@"http://www.facebook.com/sharer.php?u=%@&t=%@", urlString , title];
//Create the URL string which will tell Facebook you want to share that specific page 

NSURL *url = [ [ NSURL alloc ] initWithString:shareUrlString ];
//Create the URL object 

[[UIApplication sharedApplication] openURL:url];
//Launch Safari with the URL you created

[url release];
//Release the object if you don't need it
