Authentication in iphone

Hi Suresh,

I assume you are using a NSURLConnection to connect to the service? If that's the case you can use the code below as a guide.

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{
	NSLog(@"Entering didReceiveAuthenticationChallenge");
	NSInteger count = [challenge previousFailureCount];
	
    if(count >= 2){
		// This is the second time the authentication has failed, request review of username/password rather than use settings
		[connection release];
		UIAlertView *alert =  [[ UIAlertView alloc ] initWithTitle:@"Error" message:@"Please check username & password" delegate:nil cancelButtonTitle:@"OK"  otherButtonTitles:nil];
		[alert show];
		[alert release];
	} else {
		NSString *uName = @"Enter username here";
		NSString *password = @"Enter password here";
		
		NSURLCredential* credential = [[NSURLCredential alloc]initWithUser:uName
																  password:password
															   persistence:NSURLCredentialPersistenceNone];
		[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
		[credential release];		
	}
	
	NSLog(@"Leaving didReceiveAuthenticationChallenge");
}
