Get bounds of UIWebView content

[Sepho]

Hi folks,

I've a UIWebView with data loaded from a site. What I need to do is enable/disable a button based on the UIWebView content. All content is a plain text and I need to know if all loaded text is visible under my UIWebView element so I don't need scroll or something to view all info.

Is there any way to know if I have no more text to show to user? Maybe something to get the content bounds and compare to the UIWebView bounds.

Thanks in advance!
