title: What to do deal with the alert when installing an enterprise app?
body: <p>When I touch the button to install it will show a alertView which says
  <code>XXXXX would like to install "My App Name"</code>. 
  One is <code>Cancel</code> and the other is <code>Install</code>. 
  Is it possible to know which action I have choose? Because I want to popAction when tap <code>Cancel</code> and back to the phone homeScreen (I don't know whether it is possible) when tap <code>Install</code>.</p>
