Is this a website integrated with this iPhone app?

First of all I'm totally not advertising for this app or for this team. I came a cross to their apps and I noticed that all their apps are using the same interface.

But what wondered me are these inside开发者_Go百科 the apps are a special design websites inside their apps or what? because I'm interested how did they make it.

By the way, I'm a Objective-c beginner and still learning.

It's hard to say what they do. It's easier to say what they could do.

They could be using a custom view and drawing things themselves. Or they could be rendering the text (quoted law) to an HTML string and loading that string into a WebView, linked with a stylesheet.
