Question

I want to make an e-book reader iPhone app. Should I use UITextView or UIWebView to display the text? Which control is used by other e-book readers?

Answer 1

I would use a UIWebView, as it gives you much more flexibility in the presentation of the text. According to the UITextView Class Reference:

This class does not support multiple
styles for text. The font, color, and
text alignment attributes you specify
always apply to the entire contents of
the text view. To display more complex
styling in your application, you need
to use a UIWebView object and render
your content using HTML.

Also, UITextView uses scrolling to display large amounts of text (it inherits from UIScrollView); in an e-book reader, you will most likely want to paginate the content, so you will not want the scrolling behaviour.
