title: How to set iOS WkWebview zoom scale
body: <p>My iOS app has a WKWebView component which shows an full-screen WebApp (1280x800) with different aspect ratio and size then a iPad (4:3, 1024x768)</p>
  
  <p>I want to set the WkWebView zoom factor to 0.8, to fit it in landscape mode.
  How can I control the zoom scale of the WkWebView?</p>
  
  <p>I tried to set the the zoom scale of the WkWebView scrollview, but it doesn't scale for values below 1, even when I set the minimumZoomScale accordingly.</p>
  
  <pre><code>[self.webView.scrollView setMinimumZoomScale:0.8];
  
  [self.webView.scrollView setZoomScale:0.8];
  </code></pre>
  
  <p>Does anyone have an idea why this doesn't work?</p>
