categorise UIWebView errors and display on iphone app?

Question

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.

In this post you can find list of possible error codes, which will help you to categorize it using your specific error strings: Undocumented NSURLErrorDomain error codes (-1001, -1003 and -1004) using StoreKit

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];

you see all those "else if"s? that is why the "switch" statement was invented — Radu Simionescu, Mar 20 '14 at 09:08
Or better yet enum myEnum { LoadingFaild = -1 } Dictionary dict = new Dictionary ();; dict.Add (-1, "LoadingFailed"); Console.WriteLine ("Error loading = {0}", dict [-1]); — Nick Turner, Sep 26 '14 at 14:48
