NSURLErrorDomain error -1012

Question

I need to parse a xml file from a password protected URL I tried the following

NSURLCredential *credential = [NSURLCredential credentialWithUser:@\"admin\"           


        

Answer 1

While using a NSURLRequest to access a server, the delegate methods of NSURLConnection provides a way to be notified when an authentication is challenged.

This below sample will show one approach to handle URLs that asks credentials.

- (void)CallPasswordProtectedWebService
{
 NSURL *url = [NSURL URLWithString:@"your url"];
 NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
urlConnection = [[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];
}

//when server asks the credentials this event will fire

 - (void)connection:(NSURLConnection *)connection 
  didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{

 if ([challenge previousFailureCount] == 0) {
    NSURLCredential *newCredential;
    newCredential=[NSURLCredential credentialWithUser:@"username"                                               password:@"password"                                              persistence:NSURLCredentialPersistenceNone];
    [[challenge sender] useCredential:newCredential
           forAuthenticationChallenge:challenge];
} else {
    [[challenge sender] cancelAuthenticationChallenge:challenge];
}
}

//when connection succeeds this event fires

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
 NSLog(@"Successfuly connected ");  

}

//when connection fails the below event fires 

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
 NSLog(@"connection failed");

}

Hope this helps
