copied!<p>You will have to introduce some more code to include a download status indicator bar. At the moment you download the data with <code>[NSData dataWithConentsOfURL:...]</code>. Instead, you will make a class that uses a <code>NSURLConnection</code> object to download data, accumulate that data in an MSMutableData object, and update your UI accordingly. You should be able to use the <code>ContentLength</code> HTTP header and the <code>- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data;</code> updates to determine the status of the download.</p> <p>Here are some relevant methods:</p> <pre><code>- (void) startDownload { downloadedData = [[NSMutableData alloc] init]; connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES]; } - (void)connection:(NSURLConnection *)c didReceiveResponse:(NSURLResponse *)response { totalBytes = [response expectedContentLength]; } // assume you have an NSMutableData instance variable named downloadedData - (void)connection:(NSURLConnection *)c didReceiveData:(NSData *)data { [downloadedData appendData: data]; float proportionSoFar = (float)[downloadedData length] / (float)totalBytes; // update UI with proportionSoFar } - (void)connection:(NSURLConnection *)c didFailWithError:(NSError *)error { [connection release]; connection = nil; // handle failure } - (void)connectionDidFinishLoading:(NSURLConnection *)c { [connection release]; connection = nil; // handle data upon success } </code></pre> <p>Personally, I think the simplest way to do this is to create a class that implements the above methods to do generic data downloads and interface with that class.</p> <p>This should be enough to get you what you need.</p>
