UIWebView scalesPageToFit example.

In my experience, you need to set scalesPageToFit before the UIWebView loads. This means setting before viewDidLoad etc. What I do is set it in "shouldStartLoadWithRequest"

- (BOOL)webView:(UIWebView *)theWebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    //make sure that the page scales when it is loaded :-)
    theWebView.scalesPageToFit = YES;
    return YES;
}
