You should start/stop the progressbar in webview delegate methods.

Add following line in your viewDidLoad.

webview.delegate = self;

Add following functions in your controller...

-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    //Start the progressbar.. 
    return YES;
}

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
    //Stop or remove progressbar
}

-(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
    //Stop or remove progressbar and show error
}
