要实现此方法,您的classe应该是您的请求的委托:

[request setDelegate:self];

然后,如果请求失败,将自动调用该方法

- (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;

    } 
}
