The “prefs” URL Scheme not working in iOS 10
<p>I can't get the "prefs" URL Scheme to work in iOS 10.<br>
It's set up correctly since the same App works fine on iOS 9.</p>

<p>Is this a bug or did it get renamed / removed?</p>

<p>Code:</p>

<pre><code>NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];
if (![[UIApplication sharedApplication]canOpenURL:url]) {
    [[UIApplication sharedApplication]openURL:url]; 
}
</code></pre>
