To implement this method, your classe should be the delegate of your request :

[request setDelegate:self];

Then the method will automatically be called if the request failed

- (void)requestFailed:(ASIHTTPRequest *)request
{
    NSLog(@"Error %@", [request error]);
    if ([request error]) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"Fail." 
                                                       delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
        [alert release];
        return;

    } 
}

You can set the delegate of ASIHTTPRequest by

request.delegate = self;

which will enable you to use this method.

you can simply print the alert if error occurs using uialertView thanks
