title: How to create custom loading spinner in Ionic 3
body: <p>I have an app which has been built with Ionic 1. I upgraded this app to Ionic 3. While doing this, I am having a trouble. It is that I can't create the same spinner as Ionic 1 in Ionic 3.
  Here is a video with the spinner in Ionic 1.</p>

  <p>Also, here is a <a href="https://www.dropbox.com/s/wyan1ye8c5at3xu/3-loading-spinner.mov?dl=0" rel="nofollow noreferrer">video</a>  which I created in Ionic 3.
  Look forward to receiving a good solution.</p>
