title: Can an iOS push notification be selected to show up only in the notification center?
body: <p>I am using iOS push notifications. Can you selectively set whether a push notification appears:
  a) only as an alert / dialog box
  b) only in the push notifications center
  c) both</p>
  
  <p>Or is there no way of controlling this?</p>
  
  <p>I recognize that on the client side users can opt out. Assume for the purpose of the excercise the user has left the device on the default settings.</p>
