There are no such methods for the scrollView because it is just a container for other views, there is no implicit loading involved like with the webView.

Therefore, you will have to keep track of the state of the content manually. One solution would be to add the activityIndicator in viewWillAppear: or awakeFromNib (depending if you are implementing your logic in the viewController or a custom UIView).

Then when your content is loaded, for example in the webView delegate methods, you stop the animating and, eventually, make the webView visible, if you want this kind of animation.

Let me know if you need more help or have any questions.
