iphone - UIWebView does not scale content to fit

Question

I have a webview which is the top window in the hierarchy and has been declared as shown below. However, it does not scale pages to fit. Pages are top left aligned, but are not scaled, despite the scalesPageToFit property being set to YES. Any help would be greatly appreciated.

webLookupView = [[UIWebView alloc] initWithFrame:CGRectMake(16, 63, 289, 327)];
webLookupView.backgroundColor = [UIColor lightGrayColor];
webLookupView.dataDetectorTypes = UIDataDetectorTypeAll;
webLookupView.scalesPageToFit = YES;

Answer 1

iOS5 gives a better solution

call this from webViewDidFinishLoad

- (void)zoomToFit
{ 
    if ([theWebView respondsToSelector:@selector(scrollView)])
    {
        UIScrollView *scrollView = [theWebView scrollView];

        float zoom = theWebView.bounds.size.width / scrollView.contentSize.width;
        scrollView.minimumZoomScale = zoom;
        [scrollView setZoomScale:zoom animated:YES];
    }
}
