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;

Anybody looking for WKWebView answer, please try the below code:

extension YourViewController: WKNavigationDelegate {

    func webView(_ webView: WKWebView, didCommit navigation: WKNavigation!) {
        let jscript = "var meta = document.createElement('meta'); meta.setAttribute('name', 'viewport'); meta.setAttribute('content', 'width=device-width'); document.getElementsByTagName('head')[0].appendChild(meta);"
        webView.evaluateJavaScript(jscript)
    }
}

Remember to set the navigationDelegate of the Webview.

For Swift 3, using RunLoop's effective answer:

self.webView.stringByEvaluatingJavaScript(from: "document.body.style.zoom = 1.5;")
