Dynamically generating a local web page


We have covered how to display both remote and local web pages using the StageWebView class. It is also possible to generate HTML on the fly and render it directly within your iOS app.

Let us see how this is done by dynamically creating a web page that makes use of a PNG image and a style sheet.

Getting ready

The steps covered here are only applicable to those using Flash Professional CS5.5 and at least version 2.6 of the AIR SDK. AIR 2.0 does not support the StageWebView class.
