title: IOS Swift web view control, hiding the header and footer
body: <p>When using the web view control in IOS 10, how do you hide the header and footer ( the grey boxes)? I am using the UIWebView that I drag to the viewcontrol. The web view has the grey boxes at the time it is placed in the storyboard. I have used the web view with previous versions and didn't see these boxes. </p>
