Further Exploration

As well as useful, the segmented control (UISegmentedControl) and switch (UISwitch) classes are pretty easy to get the hang of. The best place to focus your attention for additional exploration is on the feature set provided by the UIWebView and UIScrollView classes.

As described at the start of this hour, UIWebView can handle a large variety of content beyond what might be inferred by the “web” portion of its name. By learning more about NSURL, such as the initFileURLWithPath:isDirectory method, you’ll be able to load files directly from your project resources. You can also take advantage of the web view’s built-in actions, such as goForward and goBack, to add navigation functionality without a single line of code. One might even use a collection of HTML files to create a self-contained website within an iPhone application. In short, web views extend the traditional iPhone interface of your applications by bringing in HTML markup, JavaScript, and CSS—creating a very potent combination.
