title: How to catch all iOS Push Notifications with different user actions including tap on app icon
body: <p>As per the Apple guide:</p>
  
  <p>"As a result of the presented notification, the user taps the action button of the alert or taps (or clicks) the application icon.
  If the action button is tapped (on a device running iOS), the system launches the application and the application calls its delegate’s application:didFinishLaunchingWithOptions: method (if implemented); it passes in the notification payload (for remote notifications) or the local-notification object (for local notifications).</p>
  
  <p>If the application icon is tapped on a device running iOS, the application calls the same method, but furnishes no information about the notification . If the application icon is clicked on a computer running Mac OS X, the application calls the delegate’s applicationDidFinishLaunching: method in which the delegate can obtain the remote-notification payload."</p>
  
  <p>My question is 
  Suppose user got 3-4 Push notifications from provider and all are stored in apple's notification center. If user tapped on notification alert, he/she can easily get the notification data in the app. But if user tapped app icon  on iPhone, how to get all the data related of all previous notifications.</p>
  
  <p>Thanks in advance!</p>
