iOS Push Notification ( How to get notification data when i open app directly ?)

Hi,

I used Ti SDK.3.4.0.

I have one problem. Here is my scenario

Scenario 1 I got the notification message. I click the notification. App is open and "callback" function is working. So, i got notification message. this scenario is ok.

Scenario 2 I got the notification message. I don't click the notification. I open the app directly. In this case "callback" function is not working. How to know the notification message, when directly open the application?

Here is my code:

var app = [];
    // start new code
            // Check if the device is running iOS 8 or later
    if (Ti.Platform.name == "iPhone OS" && parseInt(Ti.Platform.version.split(".")[0]) >= 8) {
        function registerForPush() {
            Ti.Network.registerForPushNotifications({
                success: deviceTokenSuccess,
                error: deviceTokenError,
                callback: receivePush
            });
            // Remove event listener once registered for push notifications
            Ti.App.iOS.removeEventListener('usernotificationsettings', registerForPush); 
        };
 
            // Wait for user settings to be registered before registering for push notifications
        Ti.App.iOS.addEventListener('usernotificationsettings', registerForPush);
 
        // Register notification types to use
        Ti.App.iOS.registerUserNotificationSettings({
            types: [
                Ti.App.iOS.USER_NOTIFICATION_TYPE_ALERT,
                Ti.App.iOS.USER_NOTIFICATION_TYPE_SOUND,
                Ti.App.iOS.USER_NOTIFICATION_TYPE_BADGE
            ]
        });
 
    } else {
        // For iOS 7 and earlier
        Ti.Network.registerForPushNotifications({
            // Specifies which notifications to receive
            types: [
                Ti.Network.NOTIFICATION_TYPE_BADGE,
                Ti.Network.NOTIFICATION_TYPE_ALERT,
                Ti.Network.NOTIFICATION_TYPE_SOUND
            ],
            success:deviceTokenSuccess,
            error: deviceTokenError,
            callback: receivePush
        });
    }
 
    function deviceTokenError(e) {
        alert('Failed to register for push notifications! ' + e.error);
    };
 
    function deviceTokenSuccess(e){
        Ti.API.info("Receive: " + JSON.stringify(e));
                //store deviceToken in variable
        app.DEVICE_ID = e.deviceToken;
        Ti.API.info("Push notification device token is: " + app.DEVICE_ID );
 
    };
 
    function receivePush(e){
         //do something with the data from Pushwoosh
 
          Ti.API.info("Receive: " + JSON.stringify(e));
 
    };
