One solution to this problem would be to create image files containing stylized text and then rasterize them and allow the user to page through them. The problem with this is that you can’t have tappable URLs or links embedded in the text.

The trick is telling the iPhone to display a UIWebView with a transparent background. I looked around for the solution to this and came across this helpful post in the iPhone Developer SDK forums.
Step one of getting a transparent web view in interface builder is to create HTML in the controller.m for the view containing the webview that contains the CSS line: <body style=”background-color:transparent”> Inside the <head> </head> sections of the html.
Step two is to set the background color of the webview to clear or transparent: myWebView.backgroundColor = [UIColor clearColor]; Continue reading Using an HTML Web View with a Transparent Background in iPhone SDK's Interface Builder and Xcode
