In here said that using MBProgressHUD is easy. But i cant make it. Here my code: - (IBAction)save{ HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view]; [self.navigationController.view addSubview:HUD]; HUD.delegate = self; [HUD show:YES]; NSString *title = [page stringByEvaluatingJavaScriptFromString:@"document.title"]; SavePageAs *savePage = [[SavePageAs alloc] initWithUrl:self.site directory:title]; [savePage save]; [HUD hide:YES]; } the progress indicator not show during [savePage save] method run, but show after the page completely saved (the indicator show for less than 1 second). I also tried this way: - (IBAction)save { HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view]; [self.navigationController.view addSubview:HUD]; HUD.delegate = self; HUD.labelText = @"Saving..."; [HUD showWhileExecuting:@selector(performFetchOnMainThread) onTarget:self withObject:nil animated:YES]; } - (void) savingPage{ NSString *title = [page stringByEvaluatingJavaScriptFromString:@"document.title"]; SavePageAs *savePage = [[SavePageAs alloc] initWithUrl:self.site directory:title]; [savePage save]; } -(void) performFetchOnMainThread { [self performSelectorOnMainThread:@selector(savingPage) withObject:nil waitUntilDone:YES]; } but still no luck. Anyone let me know where im lack here?? P.S [savePage save] is saving all website contents to local directory. I wish once the saving is complete the progressHUD disappear. Thanks
