    copied!<p>I have a <code>UIWebView</code> that downloads files (PDF, Word, Excel) from a web server requiring authentication. To do this I have handled the authentication and populated a <code>NSMutableData</code> Object as per the Apple recommendations.</p> <p>When loading the data into the <code>UIWebView</code> I don't want to hardcode the Mime Type, any ideas on how to avoid this?</p> <pre><code>[_webView loadData:data MimeType: @"application/msword" textEncodingName: @"UTF-8" baseURL:[NSURL URLWithString: @""]]; </code></pre> <p>Tried the below but always get "text/html" returned:</p> <pre><code>- (void)connection:(NSURLConnection *)connection didRecieveResponse:(NSURLResponse *)response { NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response; NSString *mimeType = [httpResponse MIMEType]; NSLog(@"MIMETYPE: %@",mimeType); } </code></pre> <p>Response headers are here:</p> <pre><code>HTTP/1.1 200 OK Cache-Control: no-cache Pragma: no-cache Content-Length: 50176 Content-Type: application/msword Expires: -1 Server: Microsoft-IIS/7.5 Content-Disposition: attachment; filename=test.doc X-AspNet-Version: 4.0.30319 Persistent-Auth: true X-Powered-By: ASP.NET </code></pre> <p><strong>EDIT:</strong> Something odd is going is happening with the headers.</p> <p>The headers I originally posted were verified in Chrome and Fiddler2 but the NSURLConnection is actually receiving: </p> <blockquote> <p>"Content-Type" = "text/html;charset=us-ascii,application/msword"; <br> "Content-Length" = "341, 79360";</p> </blockquote> <p>The below snippet was used to confirm this:</p> <pre><code>- (void)connection:(NSURLConnection *)connection didRecieveResponse:(NSURLResponse *)response { NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response; if ([response respondsToSelector:@selector(allHeaderFields)]) { NSDictionary *dictionary = [httpResponse allHeaderFields]; NSLog([dictionary description]); } } </code></pre> <p>Any idea why it's receiving this invalid header, I'm stumped?</p>
