For push notifications: how do I add action to ale

问题:

So I have push notifications sending to my application.

The code that triggers the alert is in my app delegate file (I think thats where it is supposed to go?)

How do I make an action for my alert button so that I can change to a different view?

// Set Below code in your App Delegate Class... 

   - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
        // Call method to handle received notification
        [self apnsPayloadHandling:userInfo];
    }

    -(void) apnsPayloadHandling:(NSDictionary *)userInfo{
        // Example Payload Structure for reference
        /*
         remote notification: {
         acme1 = 11114;
         aps   =    {
         alert = {
         "action-loc-key" = "ACTION_BUTTON_TITLE";
         "loc-args" = ("MSG_TEXT");
         "loc-key" = "NOTIFICATION_DETAIL_PAGE";
         };
         badge = 10;
         sound = "chime";
         };
         }
         */

To change the title of the button, use the action-loc-key key in the notification dictionary (see this section of the guide).

To do something when the notification is tapped, you can implement a few methods in your app delegate: Handling notifications.
