UIWebView transparent

Nava's solution crashes with an unrecognized selector exception. In fact, setDrawsBackground is not mentioned anywhere in the iOS SDK (perhaps this is available on the Mac?).

Instead, I recommend:

webView.opaque = NO;
webView.backgroundColor = [UIColor clearColor];

(for some reason it didn't work to set those properties via IB) and include this into your HTML code:

style="background-color: transparent;">
