Just implement -application:handleOpenURL: in your app delegate. Return NO to avoid opening the URL.

Just subclass UIApplication and override its -openURL: method, e.g.

-(BOOL)openURL:(NSURL*)theURL {
   if (shouldOpenURL(theURL))
     return [super openURL:theURL];
   else
     return NO;
}

You cannot detect clicks in regular UITextView. If you want that functionality, use UIWebView instead, and implement UIWebViewDelegate, so you can intercept clicks by implementing this method

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
