Remove UIWebView selection highlight?

Question

So in a UIWebView, whenever you press anything, a grey selection box appears. Like this:

I know you can remove it if you have access to the source code of the website, but obviously in this example I'm using YouTube, which I cannot access. Can I remove the grey highlight within Xcode?

Many thanks!

Why not use JavaScript-injection?

[webView stringByEvaluatingJavaScriptFromString:
    @"document.body.style.setProperty(\"-webkit-tap-highlight-color\", \"rgba(0,0,0,0)\");"
];
