Thanks for the tip!

Seems to me that the else enclosure is not needed since the if has a return in it.

Thanks.

You're certainly right, the else isn't required, but it does make the logic a little more explicit (to me). I'm not much of an objective-c developer, so I'm not sure what the expected convention would be.

Sorry I have no Idea of Objective-C, but is it possible to verify if the url is in the whitelist? I would like to open all not whitelisted URLs in external Safari

You can add URL schemes "mailto" and "tel" as well. That way , if you have < a href=" mailto:a@b.com" > or < a href="tel:1234" >call me</ a>, they open email client and telephone app respectively.

One issue with this fix is that iframes will also open in external Safari. Here is a solution (works with 1.4.1):

/**

• Start Loading Request

• This is where most of the magic happens... We take the request(s) and process the response.

• From here we can re direct links and other protocalls to different internal methods.
  */

• (BOOL)webView:(UIWebView *)theWebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
  {
  NSURL *url = [request URL];

  if(navigationType == UIWebViewNavigationTypeLinkClicked && ([[url scheme] isEqualToString:@"http"] || [[url scheme] isEqualToString:@"https"])){
  [[UIApplication sharedApplication] openURL:url];
  return NO;
  }
  else {
  return [self.viewController webView:theWebView shouldStartLoadWithRequest:request navigationType:navigationType];
  }
  }

Nice, thanks @Ruddiger!

update - with this code you can create a iframe with inside and external links.
you need inside links? add a relative url -> test.php
you need external links? add a absolute url with http: or https and #external
