categorise UIWebView errors and display on iphone app?-Record and share programming errors

is their any category for UIWebView possible errors? in my app i need to display the actual error occurred while loading url. i can print the error in didFailLoadWithError method , but in gives a long description about the error something like

didFailLoadWithError Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found." UserInfo=0x895fb10 {NSErrorFailingURLStringKey=https://mobilelogin.bwanet.ca/mdninput.html?csphostid=J13y8E9t000Mb3ZK00001H7R, NSErrorFailingURLKey=https://mobilelogin.bwanet.ca/mdninput.html?csphostid=J13y8E9t000Mb3ZK00001H7R, NSLocalizedDescription=A server with the specified hostname could not be found., NSUnderlyingError=0x8c68f20 "A server with the specified hostname could not be found."}

how will i categorise these possible errors and i want to display it like “specified hostname could not be found” “url timeout error” etc.

1. okay, in didFailWithError method

   if (error.code==NSURLErrorTimedOut) {
   
         errorReason=@"URL Time Out Error ";
   
      }
       else if (error.code==NSURLErrorCannotFindHost) {
         errorReason=@"Cannot Find Host ";
   
      }
          else if (error.code==NSURLErrorCannotConnectToHost) {
              errorReason=@"Cannot Connect To Host";
   
       }
                else if (error.code==NSURLErrorNetworkConnectionLost) {
                  errorReason=@"Network Connection Lost";
   
          }
                      else if (error.code==NSURLErrorUnknown) {
                           errorReason=@"Unknown Error";
   
                }
                                  else {
                                      errorReason=@"Loading Failed";
   
                      }
    UIAlertView *errorAlert=[[UIAlertView alloc]initWithTitle:errorReason message:@"Redirecting to the server failed. do you want to EXIT the app"  delegate:self cancelButtonTitle:@"EXIT" otherButtonTitles:@"RELOAD", nil];
   
   
     [errorAlert show];
     [errorAlert release];
