iphone – NSURLConnection didFailWithError not called? – Education Career Blog

Why, when an image does not exist at a specified URL, does didFailWithError not get called? For example:

NSURLRequest *request = NSURLRequest requestWithURL:NSURL URLWithString:@"http://www.google.com/images/someImageIknowDoesntExist.jpg" 
                     cachePolicy:NSURLRequestReturnCacheDataElseLoad
                             timeoutInterval:10.0;

        urlConnection = NSURLConnection alloc initWithRequest:request delegate:self;

Does not trigger didFailWithError. How can I get notified that there is no image at the url I try to connect to?

The status code in the response will be 404 when you get the connection:didReceieveResponse: method. The error method only gets called if there was an actually error fetching the URL (like the network went down, or the host doesn’t exist, etc).
