How to attach the UIProgressView with the HTTPRequest process <p>My purpose is to show a nice <code>UIProgressView</code> that display the progress of the HTTPRequest to the user (loading). It seems everything is okay, however my <code>UIProgressView</code> well configured and setup in interface builder doesn't show the progress of the request, it doesn't even appear on the screen. Here is my relevant code:</p> <pre><code>// Start request //..... //Specify the address of the webservice (url) NSURL *url = [NSURL URLWithString:@"http://xxx.xxxxxx.com/xxxxxx/webservices/"]; ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; NSString *jsonStringArray=[aMutableArray JSONRepresentation]; [request setPostValue:jsonStringArray forKey:@"liste_des_themes"]; [request setDelegate:self]; [request setUploadProgressDelegate:progress];//when i remove this line, the ProgressVie appear, although not working :( [request startSynchronous]; </code></pre> <p>My <code>UIProgressView</code> is named <code>progress</code>, does anybody know how to make the UIProgressView interact with the <code>HTTPRequest</code> Request? thanx in advance.</p>
