title: How may I check if my app has access to phone gallery
body: <p>I have an app in which I take a picture with the camera and store that image into the native gallery. But if the app doesn't have permission for that, I want the user to know that. So how do I check it?</p>
  
  <p>By the way: I store the image into the gallery with:</p>
  
  <pre><code>UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
  </code></pre>
