Why some https links are not loading the WebView. I can see that some https url are loading perfectly in the safari browser, but when I try to load the same url in the webview, it is not loading. May be because the https has self-signed certificate ?? Can't we load the url in the WebView which has self-signed certificate ?

EDIT: Now I am able to call 

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace 
{
    return YES;
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge 
{
    [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
}

Still my https url is not loaded in the WebView.

Try this :

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace 
{
  return YES;
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
NSArray *trustedHosts = [NSArray arrayWithObjects:@"mytrustedhost",nil];

if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]){
    if ([trustedHosts containsObject:challenge.protectionSpace.host]) {
    [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
    }
}
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}

  • I am processing the request using the following code ,NSURL* urlLink= [NSURL URLWithString:url]; NSURLRequest* request=[NSURLRequest requestWithURL:urlLink]; [self.webView loadRequest:request]; – Cyril May 29 '12 at 04:57

  • Am almost there. Thank you so much.I can able to get the NSData and I am displaying those in the WebView. But the thing is it is bypassing the authentication. If I access my https url, it open a dialog box for authentication , but now it is skipping that area. Any idea ?? Please – Cyril May 29 '12 at 06:02
  • Simply adding the canAuthenticateAgainstProtectionSpace and didReceiveAuthenticationChallenge methods , it is not displaying the https page in webview.SO i added the NSURLConnection delegate methods to get the NSData and calling the loadData method. But it is not working properly. – Cyril May 29 '12 at 06:49
  • Looks like the didReceiveAuthenticationChallenge and canAuthenticateAgainstProtectionSpace method is being called then why those are not loaded in the webview. ?? – Cyril May 29 '12 at 06:50
  • For your Information, Now those 2 methods are loading my office mail https url (self-signed), which will ask for authentication in the webpage. Thank you. But I do know one https url , which will pop-up a dialog box instead of webpage for authentication. This is not displayed :( – Cyril May 29 '12 at 07:08
