title: Share extension iOS, how to enable my app in Activity sheet view?
body: <p>I have created a share extension for my app,
  it works fine.
  But my app is disabled in <code>ActivityView</code> as default.
  How can I enable my app in <code>ActivityView</code> so that the user can see my app in the share sheet first time they install my app?</p>
  
  <p>I don't know if this is possible or not, but look at the app LINE, it's always enabled every time I install it.</p>
