FTWebViewController

A iOS UIWebView controller that provides pagination for multiple HTML documents and a simple way to trigger controller actions from these documents.

In addition, it will automatically set the following class names on the body element:

• visible: On the currently visible page. This can be used to, for instance, start animations when the page is shown.
• swiping: On each loaded page, while the user is swiping. This can be used to, for instance, disable animations during swiping.

This has been extracted from two in-production applications.

Usage

Initialize an instance with the -[FTWebViewController initWithPageURLs:] method, passing it a list of URLs, one for each page.

In order to handle actions triggered from the documents, initialize an instance with -[FTWebViewController initWithPageURLs:applicationScheme:], passing it a identifier by which your custom actions will be recognized, and implement the relevant FTWebViewControllerDelegate protocol method.

For instance, with a scheme of x-BananaRecipes, the following link:

<a href="x-BananaRecipes://AddToFavorites/?id=42">Add to favorites.</a>

Will trigger a call to your delegate with the following parameters:

- (void)webViewController:(FTWebViewController *)webViewController
         didReceiveAction:(NSString *)actionName
            withArguments:(NSDictionary *)arguments;
{
  NSLog(@"Action name: %@", actionName); // => AddToFavorites
  NSLog(@"Arguments: %@", arguments);    // => { id = 42; }
}

Alternatively, if you don’t need multi-page support, you can use FTWebPageView and the FTWebPageViewDelegate protocol directly.
