title: Tracking "Back" button events in iOS Google Analytics
body: <p>I use <a href="https://developers.google.com/analytics/devguides/collection/ios/" rel="nofollow">Google's Analytics iOS framework</a> to track events within my iOS apps.  I am trying to determine if it is good practice to create a tracking event when a user clicks on the Back button of a particular view.  My thought is this will allow me to see "dropoff" points of particular users within my app's flow.  </p>
  
  <p><strong>Is it valuable to create a tracking event for when a user clicks on the "Back" button of a particular view?</strong></p>
