iOS Tutorial - UIWebview - Activity Indicator Example (UIActivityIndicator) Xcode 4.5 pt2

In this tutorial, we add an activity indicator to our project. The UIActivityIndicator shows that the pre-existing UIWebView is loading or processing information. Typically, you want to use the activity indicator when you don't know the duration of the load time. The activity indicator is controlled by the UIWebView delegate protocol. The delegate is the key to the activity indicator receiving the proper instructions. If the delegate wasn't communicating with the activity indicator, the indicator would probably spin forever or not do anything. Download the final project here: http://www.mybringback.com/tutorial-series/12443/ios-tutorial-uiwebview-uiactivityindicator-example-xcode/

- (void)webViewDidStartLoad:(UIWebView *)webView
{
[_activityIndicator startAnimating];
}

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
[_activityIndicator stopAnimating];
_activityIndicator.hidden = TRUE;
}
