NSXMLParser: handling connection errors

[roko]

Hi, i need help. I have some method where xml file is being loaded from url.

- (id) loadXMLByURL:(NSString *)urlString{
	
	NSURL *url = [NSURL URLWithString:urlString];
	
	//NSXMLParser *parser
	parser = [[NSXMLParser alloc] initWithContentsOfURL:url];
	
	parser.delegate = self;

	[parser parse];

	return self;
	
}

It works fine. But i want to have ability to handle connection errors(for example if connection is torn or there is not needed file).
How can i do it? Any examples of code, thoughts and references would be appreciated.

look at NSXMLParser delegate

You can implement this delegate method

- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)

smithdale87, thanks a lot for your help. It works fine.

my code is that:

- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError {

	NSString * errorString = [NSString stringWithFormat:@"Unable to download data (Error code %i )",[parseError code]];

	UIAlertView * errorAlert = [[UIAlertView alloc] initWithTitle:@"Error loading content" message:errorString 
														 delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];

	[errorAlert show];
}

Let me know if you have noticed some bugs or shortcoming. Thanks.
