dataDetectorTypes phone link issue

this is a reformulation of this question

When i set myWeb开发者_运维技巧View.dataDetectorTypes = UIDataDetectorTypeNone; phone links (in a href html tag) are handled like this :

How can I handle phone links with the shouldStartLoadWithRequest delegate method instead?

I have not still found the cause of the problem but I found a solution.

Instead of writing phone links in anchors like this tel:myphonenumber, i write allo:myphonenumber.

Thus, the shouldStartLoadWithRequest method is called. And i can substitute allo: by tel: in my NSURLRequest object.

edit, here is the code :

- (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 )
          ) {

        // Stats
        [self recordTouch: [self tagToZone:[[webView superview] tag]]];

        // Substitution allo -> tel
        NSURL *newURL = [[NSURL alloc] initWithString: [[[request URL] absoluteString] stringByReplacingOccurrencesOfString: @"allo:" withString: @"tel:"]];
        [requestURL release];

        //return YES;

        // Launch
        return ![ [ UIApplication sharedApplication ] openURL: [newURL autorelease]];
      }

      // Auto release
      [requestURL release];
      return YES;
    }
